Think the headgasket has gone on my 850R auto, the weather was very hot here today & i noticed that the engine cooling fan has been running constantly once upto operating temp. It stayed on for the whole journey,about an hour & the temp was just above the halfway mark. Near the end of the journey i had to put the heater on to bring the temp down as it was heading to the red. On the way back (another hour/40 miles) it was even worse, the temp gauge was constantly up at 3/4 & i was driving quite slow about 40 or 50 & not kicking down, everytime i went up a hill or kicked down the temp gauge started heading for the red again & i had to crank the heater on full blast to bring it down to just over halfway. Had to keep the heater on all the way home, also noticed that the car didn't feel as quick as it normally does, felt a bit gutless when temp was right up. It never went into the red but went right up to the edge before i put the heater on & this drew it back to just over half. Hasn't used any coolant, the expansion tank is still at the max. I'm sure its the H/gasket, any thoughts ? Are T5's prone to H/gasket failure, its done 133k with FVSH.
Thanks Simon.
