Unusual overheating

[ST1G]

My car has been over heating in an unusual way. It will sometimes overheat when driving on the freeway in 70 degree weather. It rarely over heats at stop lights, and never overheats with its over 100*out. Its bizarre. I have checked for coolant leaks, and there are none, Its staying full over the last few months. I have bead the air out of the coolant system.... I put a new thermostat in about 2 years ago. But maybe it's bad?

Doubtful. I have a eurocluster. But possibly.

It is time for a new Timing Belt soon. As well as water pump. I just have been entrenched in my brothers Golf project.

I checked both tail pipes, the glove box, and cold air intake, and Tarbo for spuds. Low and behold, you were right. Look what I found in the WG
