Clogged radiator and leaking radiator are two different problems.
Either one, warm the car up first. Just turn it on and let idle until it comes to normal operating temperature. Once there, turn the car off and pop the hood. Carefully, touch across the radiator from one side to the other. If the radiator is clogged, one side will be cool to the touch. If one side is just cooler than the other, that is normal.
For leaks, just look around the radiator and its hoses for coolant leaks. Then look around the engine. Specifically the head(s), hoses, and freeze plugs. If no coolant is seen in those areas and your still losing coolant, you may have a blown headgasket and leaking coolant internal to the engine.

SOURCE: 2005 Impala Leaking Coolant and no heat

Hi lfortunato,

Try the radiator cap, if that doesn't work check your interior heater controls.... as you've already pressure tested, it sounds unlikely to be the pump..... If it was defective it would have leaked with that pressure. The thermostat may also cause the problem, if it's stuck open....

I was just having the exact same problem with mine!! (my 1999 Chevrolet Cavalier)
It turned out that replacing all of the parts you mentioned, I just had an air bubble in my system and needed to run it with the cap off and fill it up with water as the engine ran and the air escaped.
Hope that helps you!

Have the DIS module checked and the coil pack for cyl 3. If either/both of those need replaced, have it done and have the codes cleared. Then see if it clears the others.

You may need a TPS (throttle position sensor) as well.

My 2005 lumina replaced the water pump still over heating after driving for 3 hours continuously? replaced all parts with new spare parts added orininal collent as well.


At first I was going to say the cooling system may have air in it, but when you said it dried up, I'm thinking it is leaking or being burned thru the engine as you drive.
You can burn alot of coolant before you see any smoke from the exhaust pipe.
If you drive it around town for 3 or 4 days, do you have to add coolant ??

My 98 buick regal looses coolant I have recently flushed system out, replaced water pump & thermostat but my I keep loosing coolant dont see any leaks i will fill it up & in a couple of days its...


Take look down by the belt tensioner. There are two by-pass tubes that run from the tensioner to the engine. The by-pass elbows have rubber seals on them and after the coolant flush may have damaged or ruined the seals.
The only other option is the coolant is going into the engine oil or transmission oil. Check both oils and see if they look "milky"
Good luck.

I changed my water pump on my 97 camaro RS after i discovered a bad leak while flushing my radiator. i changed the thermostat as well. the leak is not coming from the pump. It seems to beabove the water...


May be coming from the intake gaskets. Coolant does pass through the heads into the intake manifold.
There should also be coolant passages in the bottom of the Throttle Body. You would see a couple of 3/4 and/or 5/8 hoses and maybe a tube goiung into the Throttle Body. This is so warm water passes through the TB so it does not freeze up.

Is there special directions to put coolant in?


Welcome to FIxYa.com



How to Fill Coolant

If the coolant system has been flushed, first add 100 percent ethylene glycol in

the amount listed for the appropriate engine application. Then slowly add clean

water to the system until the level of the coolant mixture has reached the base-of

the radiator neck. Wait for two minutes and recheck the level of the coolant

mixture. add clean water if necessary to restore the coolant mixture level to the

base of the radiator neck

When refilling the engine cooling system, add three engine coolant supplement

sealant pellets, GM RN 3634621 or equivalent, and GM approved new Ethylene

Glycol Coolant DEX-COOL GM RN 9985809.

If the cooling system is being refilled ONLY (no flush), a 50 percent ethylene

glycol and 50 percent clean water mixture should be used to fill the system. Fill

the system until the level of the 50150 mixture has reached the base of the radiator

neck. Wait two minutes and recheck the level of the coolant mixture. add a 50/50

ethylene glycol water mixture as necessary to restore the coolant mixture level to

the base of the radiator neck.

Install the radiator cap making certain the arrows line up with the overflow tube.

Close all air bleeds. DO NOT over torque the air bleed valve. The air bleed valve is

made out of brass.

Fill the coolant reservoir with a 50 percent ethylene glycol and a 50 percent clean

water coolant mixture. The proper amount of this mixture to be installed into the

coolant reservoir is listed below:

Add 0.65 liters (0.68 quarts) of a 5010 mixture of ethylene glycol and clean water

to the coolant recovery reservoir.

CAUTION: The low coolant indicator lamp may come on after this procedure. After

operating the vehicle so that the engine heats up and cools down three times. if at

any time the "TEMP' warning indicator comes on. Immediate action is required.

Air bleed vent is at the thermostat house

Coolant not circulating / fans working, water pump working and thermostat is new. Sound of water slushing in the firewall area. 1999 oldsmobile aurora 160000 miles


I assume you know that the only circulation happening unti lthe thermostat opens at its nominal temperature is through the heater core if in use. If peering into the radiator opening, you will not see more than the most minimal movement until the thermostat opens.

You may have an airlock in the system and it could be in the heater lines so if you have done a coolant change or had the system open, you need to purge the system of air.
If you have no radiator cap like many newer vehicles, this isn't as easy to accomplish. You will have to pass through several cycles of warmup and cool-down and each time refill the reservoir to the marked level with coolant mix. During this, you will have to have the heater control set to warm the interior so that the coolant is forced to circulate throughout the whole system.

Need to replace thermostat 2000 taurus


If it's the 3.0L Vulcan Engine (OHV), the thermostat is on the driver's side of the vehicle. Follow the upper radiator hose back to a metal area with three 10mm bolts. This is the thermostat housing. Undo the bolts, and there's the thermostat. Mark the back of it with the old thermostat in it (if you get one with a jiggle valve, it'll make it easier to put the new one in because the jiggle valve needs to be on top). The thermostat and housing aren't perfectly round, so you'll have to play with it a little to get it to line up. Make sure to change the gasket. The spring side of the thermostat goes into the engine.

The water pump is in the serpentine assembly. It's the larger pulley located toward the firewall. It'll be easiest to remove the water pump if you also remove the coolant recovery tank. The water pump pulley has four 1/2" bolts that you need to take out WITH THE BELT STILL ATTACHED. I can't stress this enough. The belt will keep the pulley in place so that you can remove the bolts. Take the pulley off, then the belt. Remove the heater hose at the top and the radiator hose at the bottom. There are 12 bolts of two diameters (1/2" and 10mm if I'm not mistaken). Tap the heater hose lightly with a soft-faced mallet to break the seal with the gasket. Trash the old gasket. Replace gasket (you can also line the mating surface of the water pump with RTV Sealant, put the new gasket on the new pump, and line the other side of gasket with a second coat of RTV sealant if you want a really good seal). Install the water pump and torque to manufacturer's specs. Attach the pulley to the water pump hand tight and put the belt back on. Tighten the pulley bolts. Put the coolant recovery tank back in place. Fill with coolant, start engine, bleed and check for leaks.

To bleed cooling system: Idle the engine until the thermostat opens (you'll be able to tell bacause the upper radiator hose will be uber hot and you'll feel coolant running through this hose). Squeeze all hoses in the system that you can reach, but don't burn yourself. Stop the engine and let it cool. Open the radiator cap and squeeze the COLD upper radiator hose. You'll see some bubbles in your recovery tank. You might have to monitor your coolant level for a couple of days while the final bits of air are purged through your radiator cap (that's why it's pressurized).

Hope this helps. It's not hard, but it took me quite awhile.
