Before I fitted the new thermostat the temp was regularly 70 degrees on normal flat roads at 60mph.
The old thermostat was defective as the rubber seal on the moving valve was deformed. it did not have a jiggle pin and bleed hole.
The new stat was fitted and the system bleed.
After some time at idle, I took it for A 12 mile test drive on the same roads at 60mph.
The temp now sits at 80 degrees looking straight on to the gauge and the engine sounds happier. the wife will be pleased as its now warmer in the car, and hopefully warmer in winter.
Whilst the system was apart I flushed the expansion tank of its much ( brown rust stains inside and black sediment, at some point the head gasket must have gone as the upper surface of the expansion tank inside, has a black oily deposit, but I have never seen oil in the coolant ) internal muck, and saw that the low coolant light ( the largish one above the temp gauge ) does work. I have never seen it work before.
Is it supposed to light when the ign is turned on as a test function??
it does not light until the coolant level has dropped well below the lower internal wall coolant level indicator.
next job flexi brake hoses.
ps had no feedback from gates at all!!! they have just lost a customer. the thermostat in the gates box weas not made by gates, just re boxed so sod them!!!!!!
