No heat Sign In

Hi, Guys
Need some help, got a 2006 chev. impala 3.5 L eng. No heat coming out of the vents,just cool air. Everything is wide open,inst./fan. Checked the water/coolant level (ok) still cool air.Temp. gauge stays in the center so it is not over heating.

Re: No heat Sign In

Feel the heater hoses in the engine bay when the engine is at normal operating temperature. That both should be hot. If they are hot, you may have a blend air door issue.

Re: No heat Sign In

If the coolant level is good, probably wouldn't be a bad idea to flush the coolant system out. This also means back flushing the heater core with a garden hose.

Re: No heat Sign In

Glad to see you have your heater back. Good idea to flush a Dex-cool system under the 5 year mark even though they claim the coolant is supposed to last in the system that long. Thanks for the follow up Smile

Closed as solved

Re: No heat Sign In

Dex-Cool did have widespread problems hit or miss. Pic used in CoolProfit$ magazine that discussed it in great detail.




So far so good with vehicles I deal with (not too many anymore) and will consider another EG than OE. AYOR if you change the trademark name.

DS - I didn't unlock this thread but do lock it if you wish??

Re: No heat Sign In

You probably need to thoroughly flush out the rest of the system now so it doesn't land in the heater core again.

Also pressure test for any coolant leaks be cause low coolant is the main trigger for Dexcool to sludge up.
