We had an overheating problem with the janspeed which we thought we had solved when we fitted a new thermostat but alas not. We didn't get a chance to road test it as after only 2 miles down the road the exhaust fell off. Got the exhaust fixed but didn't get a chance to test the car till last night. It now appears that the rediatormay be to blame. Starte to flush it out tonight but rain stopped play
So won't be in the sierra tomorrow

i'll be popping over in my MG ZT
