It could be a blown head gasket, crack in head or engine block, a freeze plug or water pump gone bad. You need to have it pressure tested. A pressure tester connects to radiator and is like a bicycle air pump. It puts air pressure inside the cooling system and wherever the leak is..it will leak much faster and heavier under pressure making it easier to detect where the leak is coming from.
You can borrow a pressure tester from AutoZone. They have a loan a tool program..You leave a deposit they loan you the tool, when you return tool the deposit is returned..no fee charged involved..

My 1997 isuzu rodeo overheats and has no heat what's wrong


Could be that the heater core is clogged... for the car to operate at optimal temperature (not to cold, not too hot) all cooking system had to be working properly, I had a '97 camaro, it had 2 previous owners and I had heater core issues and also the hose that goes to the expansion tank was clogged, causing the water to build enough pressure to escape trough radiator cap... anyways they're two totally different cars but seems to me you need a cooling system flush.

They sell a kit which includes a T fitting that goes in the hose flowing towards the heating core, and allows you to connect a garden hose to push water through the system with radiator cap off so all can circulate and clean up. Being careful (water pressure in houses is more than the system is designed to withstand, for instance a radiator cap can be 15 - 20 psi, depending on area, some homes have above 40 psi) is a great diy little project. Alternatively you can pay a mechanic shop to do it. After a flush, drain the radiator from bottom plug and refill with coolant always. Don't run your system with water and don't drive an overheating car, it will blow a gasket and that's when you kiss your car goodbye, repair is not only expensive but blown gasket might leave sequels on engine.

Over heat after replace themsta 2 months


If the t/stat fails in the closed position an overheat will result. I have had a brand new one fail a week after I put it it. Rare but does happen. Have you checked the rad hose, is it warm, hot, or cold during the overheat condition? Is the coolant actually flowing through the system? When its cold (after sitting overnight) remove the rad cap, look at the fluid level...normal? If so start the car and let it run with the cap off..feel the rad hose soon as it starts to get hot look in the rad (be careful if your system has a vapor lock it may spit the air out, best to have a face shield on just in case!)..is the coolant flowing? It should start flowing at some point. If not the t/stat is stuck closed or the water pump is broken/seized.

I have a 1999 oldsmobile that keeps overheating i had the radiator the thermostat the water pump and top hose replaced not used but brand new a broken head gasket has been ruled out i need help asap


Check hand brake is fully released. Why head gasket had been ruled out ? Run engine till warm, carefully open rad cap, let engine idle, look for BUBBLES IN COOLANT. IF YOU SEE ANY NO MATTER HOW SMALL, CHANGE HEAD GASKET.

Fill the rad or overflow bottle right to the top and run the engine with no cap on,if you see a constant flow of bubbles your head gasket is leaking or you have a crack somewhere in the cooling system.

Changed head gaskets @400,000 km. Now overheats. New rad, thermostat, water pump, removed thermostat, still continues to overheat.


unclip topmost hot hose when engine is running to vent any airlock.
have you checked fan rotation......?

1995 Chrysler Cirrus overheating


Probably not water pump. Engine is notourious for vapour lock.
Cooling system must be blead of air before thermostat will work. Cool bottom rad hose is a dead give away. If you are still watching this forum reply , and I will walk you through the only way I know how to make it work properly. It's actually easy if you do it my way. I have worked on lots of cars , and this engine was the hardest to bleed out. Did one Yesterday , and works perfect.

My 1992 Lexus ES300 overheats after driving it a short distance (4 miles). Checked radiator, hoses, all looks good and no leaks. Please tell me what else could cause the engine to overheat.


If you see no leaks and the fluid level is also good in the rad overflow bottle. It could be the water pump. When the car is running do you feel the hoses are hot and pressurized. Do you feel heat with your heater cranked up. The coolant may not be circulating. This would mean you need a new water pump, most likely the impeller is worn/broken inside. It can be fixed by yourself but will require some skill and time.

95 Dakota overheats


the black chunks could possibly be from someone putting a stop leak solution into the radiator first drain the coolant system fill up with clean water put in some Prestone 10 minute flush and then drain and put in a flush tee in the heater hose not the one going to the water pump but the one going to the engine block open up the drain hose and run water through until clear and refill with new antifreeze and make sure car runs until all air bubbles are out and then replace the cap

2002 V.W. Jetta 2.0 liter overheat


turn your heater on to max heat and high fan. then see if you can feel the hoses on the firewall for heat they should be hot. make sure that the fan unit on the radiatoris working if the upper radiator hose is hot the fans should be running if they are not that means that either the relay is bad the thermo sensor is bad or the fan unit is shot... please rate the solution..........thanks

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.
