If the motor runs to cool it could throw a CEL, and IMO thats on the cusp. Sadly there isn't a way to check your T stat outside the truck but if your collant temp is a steady 175 ish thats not where a 185 stat should keep your coolant.

A 185 stat, especially a "quality" one should open at least within 5 degrees of 185 degrees. With that temp, your coolant should stay in the 185 to 190 range.

Yes, but it isent. So hes good as of RIGHT NOW.

 

How about another 2nd Generation 1500

 

I GOT HEAT AGAIN!! I went ahead and flushed the heater core and put a 195 t-stat in, and the heat is blowing hot again! Thanks for your help guys!

 

how did you flush the heater core? with a hose?

i just noticed this morning that when i hit the gas i have a slight gurgle comming from the heater core...dont know if it needs to be burped or something, but it blows hot air...

 

Check your reserve tank and make sure there is coolant in there, and I would just drive it for a little while if there is some in there. If the gurgle doesnt go away flush the heater core with a regular garden hose. It took me about 15 minutes to do.

 

I would like to join this club.

gtup----thats odd about your heat situation. i have the 180 stat and i have no heating problems with it. do you think maybe it could have been sticking in the open position?

i do believe i have a blend door problem though, as the passenger side heat is awesome but the driver side heat is not-so-much, any one have any ideas?

 

I do think it was my t-stat, but I went ahead a put the OEM spec on back in because I didnt want to go through that mess twice lol.

Nim, it does sound like you have the bent door, I think there is a write up somewhere on how to fix the problem... Let me see if I can find it for you.
