well first off let me thank evryone for awnsering all of my q's.

But i have the 383 in and running dyno numbers the third of January. But now i have no heat??? Car runs great around 175-180 constent but no heat just cold air! this sucks it is cold here!

Thanks

 

?????

 

what in the hell does that have to do with an electric water pump?!

 

i dont know but it isn't working now since i installed it

 

are you sure everything is connected properly?

 

my friend put a cheap thermo in his dodge its a 180 and it never heats up.. i think its stuck.. its a 5.2 dakota runs 13's

 

kinked heater hose? clogged/failed heater core? heater hoses hooked up incorrectly/not hooked up at all? Not to insult your engine install skills, but I know its always simple stuff like that with me. I dunno (maybe my skills suck, lol), but those are the first things that come to mind and that I would check out first.

You are letting it reach operating temperature before you turn on the heater right? W/ a 180 deg. 'stat in mine, it takes a good 20 min to warm up enough to have a working heater.

 

everything is there and connected and there is coolant running to it and the floor is not wet in the passenger floor.

i have tried it after it is running awhile 30-40 minutes or so .....

 

if you have 175-180 degree, prob more if you scan it, it has to be your heater core. If you were not even moving the temp guage I would then question sensors or possibly the thermo or the waterpump
