hi, ive just installed a new head gasket on my defender 300 tdi after not paying attention to the temp gauge while towing. i went on a 100 mile round trip yesterday , temp was fine all the way there . the needle was dead in the centre of the gauge. however the last 20 miles the gauge was heading to wards the red. i thing i still have the same problem . i was watching the gauge like a hawk this time as we all know the expense . any one with the same exprience or trouble shooting ideas.
cheers
