Hi all, sorry to start another temperature thread. I did have a search through first to see if any of the other questions were the same as mine.
Basically over 3 years ago my head gasket was done on my 200tdi engine (original Defender engine).
One of the things which was replaced was the thermostat. Ever since then the running temperature has seemed somewhat high (see piccy). The engine will reach this temperature after about 2 miles and stays at this temperature.
I would also mention that I was not that impressed overall with the work on the engine; the glowplugs were left loose, the rocker cover bolts finger tight, so I can only hope the workmanship done on the interals was better, though it burnt more oil after and the performance doesnt seem to match some of the things written on here.
Anyway, the problem was that the engine overheated on the motorway following fitting a full width intercooler back last year. So the temperature issue became something to look at again. For the last year I have been running with a standard width intercooler instead. When the engine has reached that temperature is does not drop regardless until the engine is turned off.
The following has been done in the last week or two with no effect on the running temperature...
Replaced the thermostat with one supplied by an automotive wholesaler
Removed and thoroughly washed + flushed the radiator (it was rather packed with mud) and renewed lost coolant
Replaced the temperature sender today (with Britpart item corresponding to the correct item PRC8593)
The cooling system is working fine, the radiator is working, viscous fan working fine, the heater is hot etc etc. Waterpump was changed when timing belt was done couple of years ago. I believe the dash gauge is fine, it is the original and goes up smoothly and likewise goes down if the engine had been left to cool a bit.
Could this simply a case of having had the wrong thermostat both after the head gasket was done (I was told afterwards that this is the correct operating temperature) and the one I bought from the wholesaler (who asked me specifically what car it was for)?
Any suggestions would be welcomed. Thanks.
