This morning I changed my oil and installed my new JTSVP oil lines. After I was done I took the truck for a drive to make sure all was good. (Excellent oil lines and 15W-50 rock :rock Anyway, I have had the fluctuating coolant temps since I bought the truck about a month and a half ago so I let it sit and run in my drive way to see how hot it would get. It got up to about 210 and stayed there. The high speed fan never came on so I am wondering what the temp is where the high speed fan comes on. I am planning to change out the thermostat just incase it is sticky. My truck is 2005 with 20k miles so it didn't get driven much. that's why I think it my be sticky. Any ideas? :dontknow:
