SOURCE: Coolant filling up overflow bottle

You may need to ask AAA to put a radiator pressure tester on the resevoir bottle and pump it up to operating pressure(Pressure cap rating) and see if it over pressurises while it is running at operating temp,rev engine up and down and watch what the testers pressure readings do,it should move up and down in sync with the water pump.If the pressure keeps building i would have to believe that combustion chamber gases are over pressurising your cooling system.Also test the pressure cap is functioning within factory specs.

SOURCE: coolant pouring out surge tank

if one radiator hose gets hot and the other doesnt, the the thermostat is shot, but you said you replaced it, it is possible the thermostat has been put in backwards

SOURCE: Radiator is empty

Always fill you radiator & resevoir with a 50/50 mix of coolant / water. Your vehicle should have dexcool which is a red/orange colored coolant. You can buy a universal equivalent which is premixed and is yellow (not green). It is safe to add universal coolant but not green antifreeze. Premixed (it will say on jug) would be your safe bet. Fill the radiator, add to overflow tank to full cold line, run vehicle until fully warmed up. Let cool back down & then recheck.
Don't forget to check for leaks....it is not normal to have your coolant get that low. You likely are leaking coolant.

If this helps please rate me!
You can do it.

SOURCE: My coolant tank is empty.

No, Land Rover radiators do not have an access for checking the radiator itself. It is implied that if the reservoir is empty then the level of fluid is too low. It is best option to do a pressure test on the cooling system and see where the leak is, and repair it.

Where do I start to look at when engine overheats when air conditioner is on


The A/C causes the engine to work harder (that's why fuel economy suffers when it is run).

If your car has an electric fan - make sure it runs when the engine is hot. If it does not - you may have trouble w/o the A/C running if is gets warmer outside. Look for fail fuses, disconnected plugs, etc.

You may also have flaky thermostat that is not opening fully when needed to exchange hot water in the engine block with cooler water in the radiator.

First, check the coolant level. You should find a semi-transparent reservoir / tank located under the hood that has a cap marked "Coolant". The side of the tank should have two indicator lines - one for HOT and one for COLD. If the engine has been run up to normal temperature (so that it can provide heat in the car), you should see the coolant level at or slightly above the HOT line. If the engine is cold - first thing in the morning or after sitting for several hours - the coolant should be at or slightly above the COLD line. View these levels while the engine is off and the car is parked on a flat, level surface. If there is not enough coolant - you will need to add the CORRECT type for your car.

Hot Engine
(1) With the engine hot, add enough coolant to the tank to bring the level to the HOT line. You may have to check the tank several times after driving if the coolant level in the radiator is down a great deal. NEVER open the radiator cap when the engine is warm or hot!

or:
Cold Engine
(2) With the engine cold, add enough coolant to the tank to bring the level to reach COLD line. Additionally - with the engine cold - you can add coolant directly to the radiator by removing the cap. Start the engine, set heat in car to HOT and add coolant mixture to radiator until level comes up to the bottom of the filler neck. Once the engine is HOT (getting heat in the car) check and top off radiator as needed and put cap back on radiator.

Check the levels in the TANK several times over the next few days when cold. If the tank ever empties -you'll need to have this looked at by a mechanic.

2004 Kia low heat at idle hiway speeds ok


1) Coolant tank may show full but radiator is low in coolant...Cold engine...remove cap...inspect coolant level in radiator...fill if necessary,,,
2) If #1 is OK, the coolant system has an air blockage...With cold engine remove cap...Start engine...Heat control on high... when thermostat opens coolant AND air will escape from radiator...there will be coolant loss...Wait until all air escapes then carefully replace cap...When engine cools remove cap and top off coolant if required.....saailer

Water running out radiator when running with the cap off on a 3.4 motor


That's what the overflow tank is for. The fluid will spill out with least resistance. Hence, cap off. Put cap back on and forget about it. The overflow tank will fill and empty when the radiator needs more or less coolant. Just make sure the level on the o/f tank filled to the line marker. It's normal dont worry

I let my car heat up to get frost of window for about fifteen minutes. When I went out the frost was still on window and no heat coming from dash and car was overheating. I shut it off, let it cool down...


Start with engine cool, remove rad cap, start engine and turn heater on. Top up rad level and Let engine run until it get's up to normal operating temperature with cap off and add coolant as you see it go down. Watch in rad for coolant to start moving quicker, once gauge gets close to normal temperature, indicating that thermostat has opened. Wait until you see that 2 or 3 times, then top up and install rad cap. Top up coolant return bottle to proper level . You'll want to keep a close eye on coolant return bottle level for next little while. If coolant got that low in the first place, you have a leak somewhere that will have to be found.

No heat at idle


radiator coolant level and overflow tank low fill overflow tank to max remove radiator cap top off coolant level, start car and let it warm up for 5 or 10 minutes, if fluid level drops top off radiator with coolant again check for heat output if OK replace cap DONE else have someone increase engine RPMs (around 3500rpm) top off coolant level (there was air in system) replace radiator cap

Does the coolant reservoir to overflow tank need to be full for 1996 jeep grand cherokee 6cyl 4.0l gas vin s laredo if it is empty will it cause radiator to over heat.


It should have the level maintained in it as marked on it. If it is empty it will not cause over heating (it just holds the extra fluid) but a leak causing a low coolant level, stuck thermostat, clogged radiator, bad cap or improper pressure will.

I own a 1985 300zx Turbo?.I like to know why my


Your overflow tank works on suction to return coolant to the radiator. Check the line and nipple ends for any cracking (cracking on the plastic radiator nippl is very commom). The radiator nipple is not under high prrssure like the fluid under the cap (inside the coolant system). It's on the otherside of the cap and will never "stream or gush" coolant (uless you are over heating badly). As the coolant in the radiator cools it creates a vacuum and draws coolant back from the overflow throgh a small hose. You might not see any leaks as coolant heats up and travels to the overflow. It might be a very small leak and you are usaully driving around and drying up before you see it. Even with a very small crack it will only draw in air and not liquid (as liquid is way heavier than air). Also, I've seen where people have taken out (or fallen out) the tube attached to the overflow cap that goes down deep into the overflow tank. That tube should be long enough to almost reach the bottom of the tank. It's hard to know if something is missing if you do not know it was suppose to be there in th first place but it needs to be there.

Where is the drain plug for the radiator


Should be a drain **** at the bottom of the radiator that unscrews out. It looks like a wing nut has been welded to a bolt on the end of it. Another way to do this is just pull off the bottom hose.

I have a 1992 cadillac deville.i have a problem with the water going from radiator to the water reservior after it driven for awhile.what could the problem be?


This is normall oppertion, as the coolant heats up it expands just like water in a pot on the stove will boil over, hence the reson for the tank to catch it and return it to the radiator as it cools down. Now, if your coolant is not being returned to the radiator when it cools down you will most likely need a new rad cap.
