Question about 2008 Kia Spectra5

1 Answer

Heater pumps out cold air until the RPMs are higher than 2000. (No the A/C is not on) On cold mornings I'll go out and start my '05 Spectra5 and crank the heat up. I come back to it 1/2 hour later and its still cold air. I'll jump in drive away and as soon as the RMPs are up around 2000 or higher, bingo I got heat. BUT as soon as I stop at a red light and the RPMs are down cold air agian.... Whats going on?

2008, take it in for warranty work.

The reason its not working is that it uses vacuum to open the heater vent. At low idle there is not enough vacuum to open the vent, soyou get just cold air. Sounds like therer is a leak in the hose which is covered under your warranty.

When. I start up in the morning when its cold there are exhaust fumes in the car

On cold start up the computer is not looking at the air fuel mixture, only when it gets info from the ECT it then adjust the mixture. You have an exhaust leak under the hood somewhere. You may have the heater blowing at the same time bringing outside air in. This air has traces of the rich burning exhaust from the cold start up. Try turning the heater off until it is warmed up.

I have just purchased a 2008 ford transit 330. It is a nice van except the heater only blows out cold air. I have checked the thermostat with a kettle of boiling water it opens and closes fine. So I'm

check the control module that opens the heater hoses tap. Check for air blockage in the cooling system that will not allow the coolant to circulate around the heater. Loose the highest hose and run until only coolant comes out . Refill the radiator.

Heater blows cold air when the truck is idling or in stop and go traffice

a question to an answer: is your truck has any heat when you rev it 2000 rpm, or above?
have you check your coolant level? if level is low you have a small coolant leak, a water pump may be at fault, and causing air pockets in your heater core, check for leaks your self, dealer wont tell you if vehicle still under warranty.
good luck

Heater blows hot air while car is moving but cold air while idling. The intake manifold was changed last spring, the thermostat has been changed 3 times and the temperature sending unit has been changed....

That sounds like the coolant level is low. If it is not the use of "stop leak" has probably caused a partial clog which restricts the flow of water unless the vehicle is turning higher RPMS. While sitting still raise the RPMS to about 2000 and see if the heater blows hot air to see if the above mentioned problems are fact.

Heater on 2003 Buick Century only works when the rpms are up

Your likely problem is low coolant level. Check to make certain that your coolant level is topped up in the radiator and that coolant is also in the reservoir at the appropraite level as shown when on container when the engine is hot or cold. When the coolant is low, you have to have higher RPMs to get the coolant to pump through the system and heater core.

Cabin Heater cold @ low rpms

you have air in the system. put it on ramps open radiator cap and let it burp while adding antifreeze to keep it full. when finished make sure the overflow tank is up to level too.its possible the radiator cap is leaking air also so if its old you might want to replace that.

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 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.
