make sure you bleed the air out of the system on the top left hand side of the radiator or the car will overheat due to air lock

SOURCE: 1990 Subaru Liberty Overheats

Hi,

I had the same problem with my 1993 Liberty LX. Remove the thermostat (located inside bottom radiator hose engine connection - take the connection off and thermostat is inside). Reassemble (minus thermostat), reconnect bottom hose. Slowly (very, very slowly) refill the radiator and remove the bleed plug ( located beside the top hose connection to the radiator - a black square plug with a phillips head cross in the middle). When the radiator is full and clear water (no air bubbles) is coming out of the bleed point, replace the bleed plug and then the radiator cap.

Run the engine for five minutes (approx) or until normal engine temperature is reached. Allow the engine to cool down and recheck the water level - fill if necessary ensuring that the bleed plug is open and clear water is coming out of that point. Replace Bleed plug and then radiator cap. Run engine for five minutes (approx) and then test dive. If the engine overheats keep filling the radiator until there are no air bubbles coming from out of the bleed point.

This fixed my overheating problem. Good luck and safe motoring.

Have you checked to see if the radiator fan works? And have you checked to see if the water pump works? Two very important items key to overheating.

OVERHEATING, REPLACED WATER PUMP,FAN CLUTCH, THERMOSTAT & BELT , STILL NO WATER CIRCULATING IN RADIATOR,WHAT TO DO


The only other thing you need to do is get the radiatior flushed. If your certain you have a good water pump and the thermostat was not put in upside down, then that would be the only thing left that would hinder water flow. If you have a follow up question on thei get back to me and if this was helpful a vote on the thumbs up would be greatly appreciated.
Thanks

My 2000 dodge caravan is overheating and my overflow tank is literally overflowing. I have no leaks in radiator or hoses. Could it be my waterpump or thermostat or just a clogged hose.


Yes, it could be a few issues, I always believe to go the cheapest route first, so you are not just replacing parts to be replacing, Based on your description, Normally it would not be overflowing if your pump is not working, It could be a clogged hose, you would have to flush system to see if that was the case, but based on my feeling, i believe it is a stuck thermostat, If your tank is overflowing, it would have to be a main hose block, but i don't believe that is the case, i would have thermostat replaced, to confirm that, for a around 50 bucks (if you stay away from dealer) you can have the radiator flushed, which is a good idea anyway, then you will know for sure it is the thermostat, and they can put that in after they flush it, or you can put thermostat in, pick there brain, when they flush it, and they can point where it is, it is just a couple of bolts to take off, clean gasket area, replace with new gasket, after of course taking old thermostat out and replacing with new one.

I hope this helps you, (again, i think it is thermostat that is stuck) thanks Mike from fixya

I have a 1994 ford F-150 , 5- speed, 6 cylinder, Engine size 300. I have to pull over to the side of the road and turn the engine off because its overheating in stop and go traffic


If it only is overheating when going slow, then one of three problems exist; One, there is not enough coolant in the engine. Check the level of anti-freeze in the truck, and top off as neccessary.
Two,
the coolant is not circulating through the radiator and engine properly. Check the Thermostat, and replace as neccessary. The Thermostat should be changed every couple of years or so, anyway.
Three,
the air flow over the radiator is impeded somehow. Does this truck have a elcrtic Radiator fan? Or is it mechanical, being ran off the motor with a belt? If it is electric, then check the fans RELAY to see that it is working properly, and check the fan motor too. Check that there is no debris in the radiator fins.

Hope this helps.

I am having the same problem with my 94 sunfire. changed thermostat. flushed and cleaned radiator replaced coolant. no cigar. any ideas. mechanic says could be water pump but he cannot be sure and it is...


To see if it is your water pump - remove the radiator cap and start your vehicle while it is cold. the water should not circulate due to the thermostat being closed. When it is warm, the coolant should be seen to ciculate as viewed through the rad cap opening. (be sure there is lots of coolant - of course) Also if there is no thermostat - the water will circulate after the engine is started wheather hot or cold if the water pump is working. You say it is a new thermostat so I assume it is not stuck closed.

Coolant is not ciculating and not leaking it is blowing back in can i had new hose and thermostat housing put on is it air locked?


When engine is cold, take out the thermostat. Put back everything add water as needed to the radiator, leave the radiator cap out. Start the engine be careful stand in front of the radiator and where the radiator cap goes watch if the water is circulating rev it slowly and the water should circulate faster. If it is not circulating the radiator maybe clogged, inside the cylinder head where coolant circulates might be clogged or the water pump is not working.
