Why does the heater blow hot air when I drive after its been idling for 15min and not during the idle when it reaches the 100 Temp?...(it blows cold air in idle)


Firstly, a thermostat that opens quicker will not give you better heat. Your heater core may be partially plugged causing a low flow issue. Another area to check would be the water pump impeller for corrosion or slipping on the shaft. Does the vehicle's cooling system operate well otherwise?

Heater has loss of heat when Idles


Check for a clogged or defective radiator. The inner parts you can't see could be the source of the problem.

Cab heater will not run cool when idling, but is OK when at speed.


Some cars have a vacume check valve on the vacume line that
activates the air duct to open and close . If the vacume is not right
it will not work properly . If the vacume check valve is ok then check
and make sure the heater core is not clogged up

Possible, with rad cap off, let vehicle idle until coolant fan comes on then shut vehicle off for 30 minute cool down. Top up rad, install cap and drive and recheck heater operation and any overheating.

Dded anti freeze, seemed ok for a day,started over heating again when moving but pull over at idle temp drops


Welcome to Fixya

Sounds like you have a problem with the cooling system. First thing you need to check first if the auxillary fans are working from the time you are the engine is overheating. If the auxillary fans is not working then the problem would be the aux fan itself or relays. if Fan is working then you might have a poblem with the water pump.

Thank you for using Fixya!

Heater blow cool air at idle


try flushing the cooling system. sounds like the heater core may be all gumed up inside. could also be the water pump starting to fail.
