Hey guys...

Thanks for all the help so far in my previous posts.

It seems that my heater doesnt work too well...

The needle on the temperature gauge hovers slightyly above the BLUE on the far left of the gauge... Even when running for a very long time...

Any Advice would be great, as driving in -39 F isn't too fun with a LUKEWARM vehicle.

Cheers,
Steve

Check the thermostat, as it seems odd that your temp. gauge stays just past the blue region. If your engine is not getting to operating temperature, then you have bigger problems than a cold cockpit. The heater core temp. sensor and the interior temp sensor are also part of the heater control system, as is a small fan that draws cabin air past the climate control temperature sensor. Any of these components failing could result in sub-par heater performance.

-39 F??? damn thats cold.. it got down to -5 F here last night and my car started over heating after 15 minutes of driving this morning. MY thermostat actually froze closed so it wouldn't open. Eventually it thawed and all is good. My coolant must be crap (haven't changed since i bought the car used). In your case possibly the thermostat is stuck open? constantly feeding the block coolant so it never makes it to operating temp..Anywho def sounds thermostat related

Complete mod list and pics:

yup, wonky heating here too...overheating engine with no heat, mad, recently had new water pump & new fan , overheating sorted, but I only seem to get good heat coming through @ 40Mph + , damn annoying when -C's stuck in 20mph traffic..trying to find something warm to put on top of my work shirt.
