Does it run hot while driving or in traffic?
if running hot at idle could be water pump not circulating enough try revving engine some and see if temp comes down. also check your fan clutch.
if running hot going down road probably radiator

Recently had a new water pump fitted to my jeep Cherokee but it's still overheating and the heater in the car doesn't work. Any idea what might be causing this


if no leaks in hoses, then flush out the radiator etc, there maybe a plug up in system. also change thermostat. God-Bless! and hope this helps you.

1993 Mercury Tracer running hot


"rule out" questions - is coolant level OK? Any leaks, especially around the water pump? Has the system ever been flushed. out? If this is the original radiator, it could be clogged. Is the thermostat installed correctly with spring end toward the engine?

Coolant bubbling bact through resovoir.Replaced thermostat and water pump and flushed system. Still idels at 215 degrees and runs at 221. Top hose is hot and bottom hose os hot on engine side and cool on...


I doubt the radiator is plugged up. The hose should be cooler coming out of the radiator than going in (top).
If the overflow tank is bubbling it could be from the hot coolant, or you could have a head gasket leak and allowing compression - exhaust into the cooling system.

Drained radiator added prestone Radiator flush refilled and started overheating, drained radiator replaced thermostat and now I get no heat from heater,Radiator water is hot


disconnect the heat hoses going into fire wall , put hose into one with pressure and flush as it sounds like it could be bloked in the heater core,the other thing that could be the problem be the hot ,cold switch as it restricts the flow to makes the heater hoter or colder , it might need tlc or replacing as it is manaul not elec

1990 toyota pickup is running hot and when i shut


Try with the small stuff first. Replace the thermostat. Before you do that, you should flush and refill your system with just water after the flush process. The bottle of solution that you put into your radiator to flush it and clean it has instructions, follow those. Then let the car cool down and drain the system and refill it with fresh water only. Run this water for a bit and then do it once more. Once cooled back down , replace thermostat and replace the 50/50 mix of antifreeze and water.
Check engine oil level as well, low oil will overheat engines quickly.

Why is my fan running all the time


COULD HAVE BAD COOLING FAN RELAY OR ENGINE RUNNING HOT.HAVE VECHICLE SCANNED TO CHECK ENGINE TEMPERATURE.MAKE SURE THERMOSTAT PARTIALLY STOP POSITION.OR RADIATOR AND ENGINE BLOCK NEED FLUSHING.BECAUSE ACCUMULATION OF RUST WILL RESTRICT COOLANT FLOW THROUGH RADIATOR AND ENGINE BLOCK CAUSING ENGINE RUN HOT.

Found rust like material in water system change radiator and water pump thermostat .flushed system numerious times car still runs hot and water is still a rusty mess.


You may have to flush the system again. Did you use a commercial flush such as Prestone Super Flush? Plain water won't remove the rust and sludge. The Dex-cool antifreeze that GM recommends for their cars is bad about forming a gummy sludge in the cooling system. It clogs radiators and heater cores. I would suggest another flush with the Prestone product. Follow the directions closely for best results. One thing that will help is. after you drain the radiator, refill with clear water and let the engine run until the coolant is circulating good, then drain it again. Do this three or four times. This will ensure that all the antifreeze has been removed from the engine block. When you refill the radiator, use a green antifreeze that is compatible with aluminum radiators and aluminum engine parts. Do not use Dex-cool. Dex-cool can also cause the intake gaskets to fail. Make sure the new thermostat is at least a 195degree unit and that it is installed correctly. you would be surprised how many thermostats get installed upside down. After refilling the radiator, leave the radiator cap off and let the engine run until the coolant is flowing. Keep adding antifreeze each time the coolant is pulled down into the radiator. Use full strength antifreeze because the water that is retained in the block will dilute it. A 50/50 mixture won't protect below freezing.
