A few days ago while checking a dash message to "check rear lights" I saw steam exiting the hood on the driver's side. The car was running at idle maybe 15 minutes. It was the vertical hose to the bottom of the surge tank. It was wet where the hose meets the tank. Today I slid down the spring clamp and installed a new screw type clamp. I'll keep an eye on it for the next few days. I have a replacement hose and surge tank to swap out if necc. Are the temp gauges somewhat accurate? My previous XK8 was said to be very inaccurate. The gauge never moves it stays at half ( A/C on) and it's 103 here this week.

 

No the temp gauges are very inefficient, by the time they read a problematic temp it is usually too late. Our very own forum member has upgraded the gauge with this kit.

Edit :

My statement is in regards to the X308 I see your sig however says you have the 05.

 

No KC, you read to fast, current car is 2000XJ8. There are also inexpensive smart phone adapters that allow you to read data with an app like Torque through the OBD II plug.
