You new to invest in a coolant pressure test tool. To use it all you have to do is remove either the radiator cap or coolant tank cap and pump the coolant system up. One the cap of the radiator it will tell you how many psi you can pump the system up to. Normally around 14-16 psi. By using this tool you don't have to crank the engine to build pressure in the coolant system. Plus this tool can and will keep you from burning yourself on a hot surface. After you pump the system up. Just get a light and see where the coolant is coming from. I hope this helps.

SOURCE: OVER HEATING

In the fan circuit...You have a temp switch screwed on the radiator, a fuze and a relay in the fuze box plus a fan.  Swap the relay with another relay, replace the fuze.  The other fan should come on when the a/c is turned on.  If you fix the fans and it still overheats, you may have a BLOWN HEAD GASKET.  ALSO ARE YOU BLEEDING THE AIR FROM THE SYSTEM?  DO YOU SMELL EXHAUST IN THE COOLANT?

Check to see if you have flow through the entire radiator.If part of the radiator core is cool to the touch when the engine is at operating temp, this indicates restricted radiator flow. If the entire radiator core is not allowing water to flow through, cooling will not be at all efficient. Also a good idea would be to purchase a block tester. available at napa and other reputable parts houses for around thirty dollars. You remove a small amount of coolant, and put the tool in the radiator, or pressure tank opening. If there are any combustable gasses present, i'e' exhaust, this would indicate a head gasket breech, (or maybe worse) and would indicate that it's time to stop looking for a simple problems, and get proffessional help. Good luck to you!

Does anybody have a video link on how to flush the cooling system on a GM 3.1L SFI OHV 6cyl motor? I need a vid for this particular motor cause mine is still overheating & i have looked everywhere.


flushing a cooling system is the same method as any other motor

do it without the thermostat fitted
or water pump opening

sacrifice an old radiator hose to adapt a garden hose fitting
for radiator flush

air in system fix
your thermostat housing has no air bleed valve
no top radiator cap

old school way
heater on full
run motor till thermostats fully open
burp radiator hoses
wait till water is running up into over flow bottle without bubble
replace cap
turn off heater
correct level in over flow bottle

why still over heating
you fitted everything i would have ... yet still overheat
possibles
leaking inlet manifold gaskets
hose clamps loose
cooling fans spinning too slow
thermostatic fan switch faulty
aluminum radiator is a big one
air ..fins bent or some water channels blocked

or possible head gasket leak

Remove water pump


Inspect/Test/Replace
  • When replacing a water pump, it is necessary to drain the cooling system.
  • Any components--belts, fan, fan shroud, shaft spacers, or viscous drive clutch--should be removed to make the pump accessible. Some pumps are attached to the cylinder block as shown below.
f11-60.jpg Installing a water pump. Courtesy of Dana Corporation.
  • Loosen and remove the bolts in a crisscross pattern from the center outward.
  • Insert a rag into the block opening and scrape off any remains of the old gasket.
WARNING When working on the coolant system (for example, replacing the water pump or thermostat), a certain amount of coolant will spill on the floor. The antifreeze in the coolant causes it to be very slippery. Always immediately wipe up any coolant that spills to reduce or eliminate the chance of injury.
  • When replacing a water pump, always follow the procedures recommended by the manufacturer.
  • Most often a coating of good waterproof sealer should be applied to a new gasket before it is placed into position on the water pump.
  • Coat the other side of the gasket with sealer, and position the pump against the engine block until it is properly seated.
  • Install the mounting bolts and tighten them evenly in a staggered sequence to the torque specifications with a torque wrench. Careless tightening could cause the pump housing to crack. Check the pump to make sure it rotates freely.
  • The water pumps on many late-model OHC engines are driven by the engine's timing belt. When replacing the water pump on these engines, always replace the timing Test/Replace

    CAUTION
    If the radiator is filled to the top with coolant and the engine is run without the radiator cap in place, the coolant will expand and spill over as the engine warms up.

    • Drain some coolant into a clean container until the coolant level is below the thermostat housing.
    • Remove the upper radiator hose connection from the thermostat housing.
    • Loosen the housing bolts and remove the housing.
    • Remove the gasket and scrape it carefully from the surface of the housing and the mounting surface on the engine. If the gasket remains on either of the surfaces, there will probably bea coolant leak after reassembly. Some engines use a rubber O-ring to seal a thermostat housing.
    • Compare the size of the thermostat to the old one. They are of different sizes, types, and temperature ratings.
    • The temperature rating is stamped on the sensing bulb on the bottom of the thermostat. The temperature bulb faces the block.
    • When replacing a thermostat, be sure that the thermostat fits into the groove in the block or outlet housing. If the thermostat is installed upside down, the engine will overheat.
    • Install the gasket.
    • Reinstall the thermostat housing. Refill the system and run the engine or pressure test to check for leaks.
    • When the engine has reached operating temperature make sure the thermostat opens.
    • You should be able to see coolant circulating within the radiator.
    • Another way of checking thermostat operation is to feel the top of the radiator hose or use a thermometer or multimeter with a temperature probe to confirm that the coolant is warming up.
    • If the engine is overheating, but the top hose is still cool to the touch, the thermostat is stuck closed and must be replaced.
    NOTE When a paper gasket is used and the recess is in the thermostat housing, it is a good practice to position the thermostat into the recess and glue the gasket to hold it in place. If it falls out of its groove during installation, the outlet housing can be cracked or a coolant leak will result. Before tightening the water outlet housing, try to rock it back and forth to be sure it is flush. Housings are often cracked during this step. belt.
  • Make sure all pulleys and gears are aligned according to specifications when installing the belt.

I filled the cooling system and my 97 ram still wants to run hot over 200


when was the last time you changed out your thermostat and what temperature thermostat did you put in if it was 195 degree your not running to hot at 200 did you flush out your system clean it real good.
check your drive belt (fan) not worn out or to loose for water pump, radiator core blocked or grille dirty, buy or have radiator cap tested it must maintain radiator pressure also check ignition timing.

I just got a new thermo housing water pump thermostat and gasket antifreeze had the engine flushed had the engine detailed a new serp belt and an oil change less than a month ago for the same problem....


Sadly as vehicles age things like gaskets, seals, hoses and such items become brittle and weak - They are prone to failure and are listed as "check or replace " in the manufacturers service tables at mileage and-or time. The leak may be any item associated with the cooling system, a pressure test should find it. I recomend you have the cooling systems hoses replaced to prevent problems when the leak is repaired.

Just need to know were the water pump on montero sport 1998 3.0 Ls engine????


It's under the timing cover on the front of the engine. I have pasted autozone.com instructions to replace the water pump below.


3.0L & 3.5L Engines

  1. Before servicing the vehicle, refer to the Precautions section.
  2. If necessary, properly release the fuel pressure.
  3. Drain the cooling system.
  4. Remove or disconnect the following:

    Negative battery cable
CAUTION Wait at least 90 seconds after the negative battery cable is disconnected to prevent possible deployment of the air bag.

Upper radiator shroud Accessory belts Air conditioning compressor tensioner pulley, if equipped Cooling fan and clutch assembly and the water pump pulley Thermostat and housing on 3.0L, 3.5L engines Water outlet, gasket and houses Radiator hoses from the water pump Crankshaft pulley(s) Timing belt covers. If the same timing belt will be reused, mark the direction of the timing belt's rotation, for installation in the same direction. Be sure the engine is positioned so the No. 1 cylinder is at the TDC of its compression stroke and the sprockets timing marks are aligned with the engine's timing mark indicators. Timing belt Water pump bolts are different lengths, note their positions before removing. Water pump from the block Water pipe connection and O-ring

To install:
  1. Clean and dry the mating surfaces of the block and water pump
  2. Install or connect the following:

    New O-ring on the water pipe connection, wet the new O-ring with water to aid in installation Water pump, with a new gasket, Torque the bolts to 17 ft. lbs. (23 Nm) on 3.0L and 3.5L engines Alternator bracket bolt to 17 ft. lbs. (23 Nm) Timing belt(s) and covers Crankshaft pulley(s) Thermostat and housing on 3.0L, 3.5L engines. Torque the bolts to 12-14 ft. lbs. (17-20 Nm). Radiator hose to the water pump Water outlet, new gasket and houses. Torque the bolts to 12-14 ft. lbs. (17-20 Nm). Water pump pulley Cooling fan and clutch assembly Air conditioning compressor tensioner pulley, if equipped Accessory belts Upper radiator shroud Thermostat and housing on 3.0L, 3.5L engines Negative battery cable
  3. Refill the radiator with coolant. This cooling system has a self-bleeding thermostat, so system bleeding is not required.
  4. Run the vehicle until the thermostat opens and fill the overflow tank. Check for leaks.
  5. Once the vehicle has cooled, recheck the coolant level.

2001 vw beetle service manual ? need to change water pump, how hard is it? dont look to bad.


Check this procedure to how to replace a water pump (DIY Complexity: Moderate / Time: 3.5 hours):

Parts:
1. Water Pump

Tools:
1. Screwdriver
2. Scraper
3. 3/8 in. Drive Ratchet
4. Cooling System Pressure Tester
5. Needle Nose Pliers
6. Socket Set
7. Radiator Hook Tool

Supplies:
1. Coolant
2. Silicone Sealant

Steps:
Step 1 With the engine off and cold, open the hood and locate the vehicle’s water pump.
o Tip: Safety Tip:Always wear safety glasses when working on your vehicle. Wear other personal protective equipment (PPE) when necessary, for example latex gloves or safety shoes.
o Tip: Before removing the radiator cap, squeeze the upper radiator hose to verify that the cooling system is not pressurized.

Step 2 Remove the radiator cap.

Step 3 Install cooling system pressure tester. Apply the pressure indicated on the radiator cap or in the owner’s manual.

Step 4 Inspect cooling system components for leaks.

Step 5 Place a drain pan under the radiator. Open drain valve or remove the lower radiator hose to drain cooling system.
o Tip: Depending on the vehicle, lifting the vehicle may be required to gain access to the lower radiator hose.

Step 6 Remove the drive belts or serpentine belt.

Step 7 Remove any hoses connected to water pump.

Step 8 Unbolt water pump from engine. Remove the water pump.

Step 9 Using a gasket scraper, clean the mating surface on the engine block.

Step 10 Install new water pump and new gasket. Tighten bolts to manufacturer’s specifications.
o Tip: You may want to use a light bead of silicone designed for water pumps.

Step 11 Re-install any hoses and belts that were removed.

Step 12 Re-install drain plug or lower radiator hose.
o Tip: Squeeze the radiator hose. If it feels soft you may want to replace the hose at this time. Always use new hose clamps.

Step 13 Refill radiator with a 50/50 mix of coolant and distilled water, then pressure test the cooling system and check for leaks.

Step 14 Fill overflow reservoir with same mixture.

Step 15 Leave the radiator cap off, start engine and let it idle. You should see the system“burping” bubbles of air. Refill the radiator to the top.
o Tip: Most air is expelled after a couple minutes of idling. Be cautious of potentially hot fluid overflowing.

Step 16 Install radiator cap.

Step 17 Road test vehicle, keep an eye on the engine temp gauge if vehicle runs hot, there still might be an air pocket in the cooling system. The cooling system should be topped off after vehicle has fully cooled down.

Good luck.

I have a 04 VW Beetle with a 2.0. Just replaced the thermostat. Now it is leaking coolant badly. I have checked and seems to be comming from the middle of the engine. I have checked both the thermostat and...


If it is not coming out of any hose connection, and it is in the middle front area...it is most likely the water pump. You may be able to get a look at the pump, which is run by the timing belt. The pump mounts behind its rear cover unfortunately. Some water pumps have a small hole that you can check for water leaking out to indicate it is bad. If not, you will have to remove the timing belt rear cover to check the water pump gasket area for water leaks.
A head gasket is not likely unless you find water in your oil.
Good Luck!

You may want to do a inspection of your cooling system, here's a list that might help,
  • Check the thermostat, if it's defective replace it.
  • Check the coolant in the reservoir tank, it should be at the proper full level.
  • Sometimes when you change a thermostat there's a possibility you could get air in your coolant lines from having the coolant system opened up, this could keep your coolant from circulating through your system, if so you will need to bleed the air out of the coolant system.
  • The water pump should be inspected for leaking coolant out of the weep hole's, when a water pump go'es bad it may leak coolant, which would mean the seals on the pump are bad, also listen for squealing noise's coming from the pump when the car is started, if it squeals the bearings are bad, there is also a possibility the water pump fins are wore down from corrosion, there is no way to inspect this without removing the pump.
  • check the drive-belt for wear and tension, a bad tensioner or a bad drive-belt could have an effect on the operation of the water pump.
  • check the pressure cap on the coolant reservoir tank for good pressure, when you remove the cap you should hear a hissing sound this means you have good pressure in your cooling system, check for corrosion or build up on the cap, clean the cap if necessary, also check the coolant in the reservoir tank, it should be clean, if not you might need to have the cooling system flushed, during the flush you can observe if the coolant has a good flow through the system.
  • check the large upper and lower radiator hose's for crack's, swelling, and proper coolant flow.
  • Check the operation of the cooling Fan, and circuit, cooling fans use relays and fuses, some vehicles use more than one cooling fan, if your vehicle has two cooling fans there should be two relays and two fuses one for each fan, first visually inspect the fuses if one or both are bad replace them, you can test the relay or relays for continuity by removing them and doing a proper continuity test according to your relays circuit diagram.
  • Check the coolant temperature sensor, most coolant temperature sensors are located directly in the thermostat housing, this sends information to your pcm which determines when to turn your cooling fan on and off, if it's defective replace it.
  • Inspect the radiator grill for damage or debris build up.

Overheating problem


water pump. water pump. water pump. i am a vw dealer tech and on 2.0 and 1.8t beetles the water pump impeller is plastic, and what happens is usually another component, fans, fan control module (under battery tray), thermostat, fails and because the impeller is plastic with just one overheat the plastic becomes brittle and shatters, pull the water pump out and you will see the impeller in 3 or 4 pieces. replace water pump and make sure t stat opens, fans come on (a/c off) and proper water pump flow.
