Hi All,
I have a 97 Ram 1500 Sport with a 318 (5.3). I had the motor rebuilt a while back and ever since the coolant temp runs about 220. I took a 2600 CFM fan and put on it and when I turn it on the temp starts to drop then the ECM adjusts and takes it right back to 220. I'd like to find a programmer for it but haven't been able to locate one that will let me change the temp setting (has a 180 thermostat). I know I can buy a new ECM but are there any other options?
Thanks to all for looking at this.

 

SORRY! I've put this in the wrong place!

 

Thermostat prolly stuck closed or coolant passages blocked.

 

Thanks, I've changed the thermostat twice, once a new 190 and the last time a new 180. No joy so far. Will look deeper.

Thanks for your service.
