Fit 2007 dodge nitro 3.7 perfectly
Fit perfectly and so far no leaks or anything like that. I've had it installed for 6 months and no issue. I was losing coolant very slowly, like an ounce a month or something small like that. Never saw a leak or spots but after installing this, coolant level has stayed good. Also my temperature has remained what it was before replacement so its as good as Mopar brand.

Buy from a different company. Junk
The housing is ok. Fairly easy to install. The thermostat is junk. The thermostat opens around 140 degrees creating check engine light. Had to get another thermostat and do the job a second time.

Outlasted the vehicle
Very well made. Included a thermostat. It was an easy swap out that fit perfectly, hoses and all, on a 2005 Jeep. No complaints.

Do Not Buy! You will have to do the job twice!
Negative reviews are correct. Adding mine. Thermostat stays open way too low, engine runs cold, now I have a check engine light. 2008 Grand Cherokee 4.7L. Now I have to do the job...again. This is not ok. Amazon/Dorman fix this, NOT compatible!

Temperature is not right for my truck.
My 2002 ram with the 4.7 now runs too cool and throws a code saying it doesn't warm up fast enough. Now I have to replace this one after only a couple weeks. Waste of time and money. There is nothing indicating what temperature this unit is set at it just says "fits my vehicle". My motor needs to be at 195 degrees and this is nowhere near that.
