Hi,
Dare I say it but my P38 has started to overheat!! I know a complete surprise, but I was wondering if anyone could help me as to where to start.
Firstly it does not lose any water and there is no obvious signs of head gasket failure. I have also changed the thermostat.
On a normal run to work including 25 miles of motorway she will sit happily with the needle just about the 12 o clock mark maybe a mm past. If the ambient air temp is lower than 15 degrees there is no overheat problem at all.
If ambient temp is higher than this, she will still sit at normal temp until there is a steady incline, and then the temp will rise above the normal 12 o clock to the third white mark and once slightly beyond, but hasn't entered the red.
Once at the top of the hill the needle will return to normal temp, over the next mile or so.
Whilst she is not overheating there is an overheat problem, as already mentioned I have changed the thermostat but this has not changed anything.
I have recently changed the coolant after changing the matrix o seals.
I have checked the water pump in as much as there is flow into the expansion tank, only a small trickle at idle but if I rev the engine 2000 rpm + there is a stream a water.
The question is where would be the next place to check, or is there something obvious I am missing. Any help is appreciated and I know overheating is a thread take is discussed time and time again.
Many Thanks
Paul
