Hey everyone

starting Wednesday I noticed that my truck was starting to run a little hotter than normal anywhere from 4-10 degrees, nothing has changed in a long time so it's got my attention for sure.

I have changed the oil recently, and the water in the cooler reservoir is still sitting at the full line so I'm not losing water.

I'm thinking that maybe the cats are starting to go south & plug up on me since my mileage is starting to dip a bit as well could this be the cause?

I'm not terribly worried yet since I only hit 190 today with temps in the mid to high 60's driving through small hills on a 4 hour trip.

 

Rob- Do you run an Edge or what? I thought these trucks came with about a 192 or 195 thermostat from the factory.

 

I have a gryphon installed, as for the thermostat I have never changed iŽ, maybe the previous owner did, but I know I have no problems running high 190's in the summer
