 Subject: Anyone put a 180 therm in a 4.7 Dakota?
IP: Logged
Message:
Has anyone changed their thermostat out from a 195 to a 180 in a 4.7 dakota or durango? Did it have any affect on the running/performance/mileage other than the obvious cooling affect? Im fixing to change out the one in my dakota, and wanted to go a little cooler being in the south where the humidity is so damn bad, and wasnt sure if i should do it or not...
THANKS
TONY

I put one in my truck. I didn't notice any performance gains. It was before I did my s/c though. I am sure with the s/c I would have notice something. I occationally get an engine light because my engine is cooler for too long at times. Normally just in the winter though.

I've done it too. Even tried the 160 t-stat 9no error codes in Arizona) but saw nothing from it. Running the 180 for about a year straight and no clutch fan unless I tow something HUGE.
Temp stays a little lower on the gauge unless towing up a hill.
No power increase I could tell. But our intakes are PLASTIC without coolant flowingin them so cooler temp water may not do jack for us.

Where did you guys or gals get your thermostat from? I have called the local Napa and others, and no one lists a 180 for a 4.7.

Nope they don't list them. But the ones from the older engines DO fit if you cut a notch in them for the gasket.
Also, they don't have as long of an extension on the sensor into the water jacket. But, they DO work.
I bet I have pics still on my web site...
Wow. Looking at the date I've had this done a while! Taken form my old cam corder before i got the new digital cam corder.
Side by side comparison.
I've had the 180 back in there for a long time. It stays about a smidge off of the C line unless I tow up a hill. Then half way is usually max as long as I throw the clutch fan on.
A future mod will be a custom shroud housing TWO electric fans. I will stage them with one of my home brew electronic controllers so they only operate as single or dual depending on temp and if the A/C is on.

I bought a Robert Shaw (I think it was a T-180) from Autozone for something like $7 and installed it without having to notch anything at all. It has been in there for something like 70k miles now and I have had no problems. The only time I had a problem with heat was when I pulled my clutch fan and only when sitting at a stop for a period of time.
