2009 Jeep Patriot Question: Where are the two thermostats located on this car



lowellqc, 2.4L 4 Cylinder, Forest Lake, MN, January 02, 2011, 02:15

No codes.... but it usually won't get past 1/8 on the gage [ that is ok ] after 20 minutes idle time ...usually runs at 3/8 on the gage after an hour of driving...never gets to 1/2 on the gage. Had the local dealer replace them at about 15000 but it didn't change anything...now they say the car in within specs as designed...

    It would be good to know what the temperatures really are. The dash gauges are not considered scientifically accurate instruments so I'd get a Jeep specialist to check the temps with an accurate instrument and see if there's really a problem. You don't want to run an engine cold, it's bad for emissions, will shorten oil and engine life and reduce fuel economy.
