Question about Mitsubishi Montero Sport

1 Answer

The heater only works if you go above 2 rpms. It seems the faster you drive the more it heats. Also...it blows heat if your going up hill and when you go downhill it starts to blow cool air. It takes a long time before it even heats up. It only blows heat if your on the freeway going at a faster speed. I have tried everything. It is the most bizarre thing. Please Help!! Pamela

03 civic heat doesn't work unless driving


no that is a water pump or a stuck thermostat. see when you are driving the coolant is going through the system which means the faster you go the faster the water pump goes and more pressure on the thermostat. you have a stuck thermostat

97 subaru outback 2.5 over heats going up hill at about 3000 rpms


Check the oil again. If the level is higher than it was after you changed it and/or is pasty again (kind of like milkshake) then you have coolant getting into it--most likely through a leaking or blown head gasket.

Sounds like you should be replaceing your drive belt to the water pump or the water pump needs to be replaced,idleing seems to not have the capacity to keep you heater core full due to either of the above.

Heater only blows hot air when engine rpms are up


Since the fan is electrically operated it is not the problem.it seems like more of a waterflow problem:the faster the engine turns-the more the water pump turns.i am only guessing but it seems like it could be low on antifreeze or your water pump is failing..good luck

No Heat in 99 Taurus


Just finished fixing my daughters 1999 taurus heat. It would blow warm only when running down the road. At idle it blew cold. I started with replacing thermostat, and water pump because they are the easier fix. Still did not help. Then I replaced the heater core. A daunting job but not that hard to move the dash slighly out of the way to replace. There is a good write up at tarusclub.com. After that, heat was better but at idle, it would still blow cool sometimes. Researched and found answer. Park car on the steepest hill you can find with front of car up. Start car and take off reservoir cap. Let car warm up and keep rpms about 1500. After a while the fluid will come running out of the car and all over the place but it will bring air bubbles with it. Reduce rpm, add more fluid and repeat about 3 times. It will make a mess but after that, the heater works perfectly. We get heat long before the temp gage indicates any and it never blows cold unless you lower the temp.

Heater


You did not say what engine you have. I will assume it is the 3.5 liter 24-valve engine.  This is most likely due to air in your cooling system. The only way to eliminate the air lock is to vent it out at the thermostat housing.  If there is air in the system, the engine will overheat and also fail to send heat to the heater.  When the engine is running at high RPMs the problem is mitigated, but it is trapped air that is probably the culprit.
