I haven't been having good heat in my cab lately. It'll get alittle warmer than outside but that's about it. We disconnected the two lines and sprayed water through them and they seemed fine..

Do I need a complete radiator flush? I have a 180* Hypertech Tstat in there but I wouldn't think that would cause my truck not to put out a lot of heat.

Any ideas?

Well, we just unclamped the two heater hoses and forced water through them. Not sure if that's considered flushing the heater core or not..

Your running a 180 degree Tstat and that is your problem. I had crappy heat to until I switched back to the 195 and its nice and toasty again. Pull the SCT and 180 for the winter and go back to stock. Not nice to run an engine at 180 in this weather anyways.

Seeing what John ^up there experienced, I'd say the same. Swap back to the 195. Shoot if you can, leave the SCT, might make it even toastier. :D

I pulled mine because mine are set for 91 and 93 octane. I wont use ethanol laced fuel so the lower octanes arent an option for me. What tunes ya got Phil? If you have the 87 you could try that and see what the pinging is like if it is there.

Ok thanks guys. I don't even know where my 195* tstat is though...

And just the 87/91/93 tunes Sean put on for me. I never noticed pinging when I used this. I had the 93 tune on before with 91octane and still never heard anything.

Lol go buy a stant super, cost me $15 locally up here, should be $5 locally for you :p Easy to change out to man, if I can do it you can hahah. Just gotta pull the air breather, that first bracket, alternator and a/c compressor.

Yes because you have a 180* stat in right now. The pinging comes from the heat, its pre-detonation IIRC. I used the 91 octane tune with a 195* stat and good grief did it ever ping. Maybe try the 87 tune but dont count on no pinging. Sean wrote me up a 91 regular, 91 tow and 93 performance which I normally use :D

Got the 180 switched back to a 195 and my heat is back. :)

Had to put my programmer back to stock though. Not taking a chance for the pinging issue.

What kind of outside temps did you have when this was going on?

Since you have the 180* stat out try testing it in a pan of water and thermometer. I am wondering if the t-stat was sticking.

I have been running a 180* for 2 years now with great heat. Tested with 15* weather last week. Worked perfect. I was worried about it not heating properly when I first installed it.

Just thinking. I know, I know. STOP. :emotions133:

Just around 20-30* it has been. It wouldn't be cold air blowing, but it wasn't too warm either.

But I have good heat now so I guess that was it. Heater core wasn't clogged at all. He said that 180* tstat worked perfectly fine too.
