I know this is not giving the forum a whole lot of info but here goes.....I picked up an OBD2 scanner recently to reset my CEL on my Lexus LS430. I needed to pick up an air cleaner for my LS430 so I took my 2010 Jag XK with the original water pump and almost 11,000 miles for a run. It's stupid hot here in Florida with crazy humidity. When I got back and pulled into the driveway, I decided to to hook up my OBD2 to look at the temp reading for the hell of it with the car standing still. I shut the car off for about 10 minutes and then after starting it and letting it idle for another 5 minutes or so I was reading 208F. I assume driving it on the highway might bring it down somewhat. Am I in the ball park? PS.....I looked for any wobble and didn't notice any.

 

Temp is in the normal window. 195*F to 215*F Anywhere in there is considered normal.

 

Thanks.....that engine throws off alot of heat!

 

No different then my 5.3 L chevy V8
