Heater

[smales09]

Dealership says heater working fine, but does not blow hot air. Any suggestions?

[MT-2500]

A little more info would help.
Year make and model trans and engine and mileage?
Is it under warranty?
Have you checked water/coolant level?
Is the engine running at right tempture?
What temp does the gauge say?

Yes give us more details. I am going around with my dealer on my 2001 S-10 Crew. I have a gurgling sound in my heater core that they say is normal but I think the Dex-Cool is screwing up my core. There are some know problems with trany fluid sucking into the vacumm lines on the 4WD models and causing vent problems.

Acid Flush your cooling system then replace with green and change your rad cap..(even if you go back to dex, change your rad cap, that should cure the gurgling)

Sorry, its a 98, 4WD model. the running temp is fine, as well as the coollent level. The fan just blows cold air. Thanks
