SOURCE: Overheating

Who did the replacement of the parts? Was it done at a shop or at home? Do you know if the cooling system was "burped" after the parts were installed and the coolant was refilled? If you're not sure, burp the radiator. This is easy to do. Jack up the vehicle so that the thermostat is angled upward. Start the car and let it idle until it's 3/4 of the way to overheating, then shut it off and allow it to cool down somewhat. Then pop the cap, let the coolant drain down, and refill it. Restart the vehicle and repeat the process, until the coolant level doesn't drop anymore.

What you're doing is this - anytime the cooling system is opened up, especially when the fluid is drained and parts are replaced, air gets into the system. When you reassemble and refill with coolant, you trap air bubbles in the system. Since the system is sealed, it operates under pressure. As the car runs, the coolant and the air bubbles are circulated. The bubbles get caught behind the thermostat (if you have it angled upward) and keep it from opening. This causes the engine to heat up to the point of overheating. You want to allow it to get about 3/4 of the way to an overheat so that you know the air bubbles are blocking the thermostat. Shutting down the car stops it from heating up to the point of damage, and allows the system time to cool off so that when you pop the cap, you don't get an explosion of coolant in your face. Once it's cool enough to open the system, you open it and release the pressure. This allows the thermostat to open and bleed the bubbles upward to the open cap, where they "burp" into the air. The space they took up fills with coolant, which is why your coolant level drains down. You top it off and repeat to make sure that all the bubbles are out. You'll know you're in good shape when you let it run and it gets to operating temperature and doesn't overheat anymore. Let it cool that final time, open the cap, and since you have no air pockets left in the system, nothing will burp out and your coolant level won't decrease. Then you should be good to go - put the cap back on and drive away happy.

SOURCE: fan keeps running for 15 minutes after engine is shut on my Hond

It's normal for cars with electric rad fans. The 15 minutes is excessive but your engine must be running very hot. Try changing the thermostat and remember to turn the AC off a minute or so before shutting the engine off. Some engines don't circulate coolant very well at low RPM's and it's better to downshift to a gear that will keep the engine at 2K to 3K RPM when the engine is running hot { even with an automatic transmission shift into 3rd or D instead of overdrive [D] }.

Heat problem. Heater only works sometimes. Blows out almost AC temperature majority of the time. No engine overheating problems. May or may not be related to actuator issue (vent always open)


Check to see if your heating system is properly filled. Air in system can often prevent the proper flow of hot coolant into the radiator core resulting in your issue.

Why does it take a long time for heater to come on?


The heater works with the hot water of the car radiator, on colder days it takes the water sometime up to 15 minutes to get hot. The heater in the car does not use electric heating etc, the safest form of heating inside the car is done through a fan running over a water heated core.

My Venture overheated and I get cold air in passenger compartment when it is supposed to be heating


Normally, if an engine is running hot and the heater is blowing cold air that means that the coolant level is low. Make sure the radiator and overflow bottle are full. Leave the cap loose for a day or two and keep topping up the coolant level. This should bleed out any air and give you back your heat. If it is still running hot then you will probably have to change the thermostat. It should be changed every couple years irregardless if it is still working. Hope this helps.

2001 FORD WINDSTAR stopped heating


Check top rad hose for heat. When enging has been running for 10-15 minutes, shut off engine and feel top rad hose. It should be very warm if not hot to the touch. If it is not hot, Change thermostat. It is located under housing that top rad hose mounts to on engine. You can get a eplacement at any auto parts store. Get a failsafe one. If it fails it does so in the off position only and will not cause overheating problems if it fails.
If rad hose is hot it is a problem with your heater, possibly plugged

99 Firebird still overheating after repairs and antifreeze


overheating is most likely a bad thermostat, but the coolant loss is a second big concern. Does the exhaust look like steam? You could have a cracked block and the coolant is leaking into the engine. Also check the oil for contamination.
