The hot air from the vents begins to cool down when the vehicle is stopped or slows down.


sounds like a possible plugged heater core, restricting the flow of coolant. those require a special tool to remove, quick disconnect, just remove both hose from the heater core and back flush the heater core with a garden hose, NOTICE DO NOT DO THIS WHILE HOT IT WILL BURN YOU, this can make a mess, flush it both ways untill it flows clean and with even pressure, then refill the coolant and road test the vehicle to see if is changed.

On hot days...the engine sputters and eventually quits...won't start until it cools down.


My first guess would be a relay or the ignition module.
Do you have spark at the plugs when it won't start ?

Is there a heat shield on the starter


I don't think there is a heat shield on the starter but, I wouldn't think that would be you're problem. I would try changing the ignition module. It's on the engine block, drivers side, I think. Usually when they are going bad they will shut off engine when they get hot. It won't crank until it cools off. After it cools engine will crank and run good until it gets hot again. Good Luck.

Bravada won't start when it's hot


Had a similiar problem with mine. Ignition control module will overheat and the vehicle will not be able to restart until the vehicle and ignition module cool back down. Ignition control module probably bad.

Ford taurus 2001 car start but once the car is cut off it won't start up again until it cools off the car is not running hot.


After you kill it, when you try to start it back up, does the starter turn the motor? Or is it froze up (will not turn over)?

Car runs great until it get about 180 degrees andthen shuts off let it cool off a lil bit its starts back up until it shuts off again why


I am thinking that perhaps the temperature sensor is reading wrong and therefore sending a message to the computer that the car is running too hot. This can happen, my VW presently reads 20 hotter on the guage than a heat gun records at the temp sensor location on the head. If you have access to a heat gun it might be a good idea to check out the actual temperature, but it probably won't hurt to change the sensor.

The other problem that occurs to me is the oil sending sensor. While a temperature sensor won't shut an engine down, the oil sender can. If it is reading a large drop in oil pressure it will shut the engine off. Since oil gets thinner as it gets hot, perhaps a defective sending unit is reading it as too low. Once the oil cools off, it would restart until the temperature gets too high again. I would think that upgrading to a heavier oil might cure the problem. I don't know what you are currently usung but certainly you could go to 10W30 or 10W40 without too much trouble, at least for a test. Hope this helps.
