Hi Everyone. Long time reader, first time poster!. Thanks in advance.
So I have a 2007 GMC Yukon XL Denali with a 6.2. I noticed my water pump was leaking a bit of water, not much so I decided to change it out. I also took the opportunity to change the t-stat. While I was changing these out, I noticed the radiator had rust and corrosion on it, so I changed it out as well. To complete the whole project, I changed the overflow expansion tank.
So I am in AZ and it is 50 to 80 degrees out, but it will start to get a lot warmer here shortly. The car will run at 217 and up to 228 at idle, and if I am not moving and rev it up, the temp will drop right away to 208. I am using my digital scan tool, to get these temps. I have also changed out the coolant temp sensor. I pulled the thermostat out, and it will run at a max temp of 190. I put a different, brand new thermostat in, and it is doing the exact same thing of running at 217 to 228. High speed fans kick on when the AC is turned on.
I am stumped as to why after changing all these components, it is running hot? Before changing everything, it always ran at 210 unless I was pulling my utility trailer up a hill or mountain road. Any help would be greatly appreciated.
