me needing some help
Recently got a cav gsi but it has a few niggles, one of which is its overheating randomly. Its most odd...
Sometimes it runs bang on 90, sometimes a little lower, but more often or not its running at what would be the 100 mark. I have sussed out that the fan isnt cutting in which is something i need to sort but thats isnt the cause. Have just been swansea > bristol > swansea and it was bumping around the 100 all the way even at 80ish on the motorway (proving the fan isnt the cause), even raised halfway from the 100 to 110 at one point.
There is plenty of coolant in there, its recently been changed and flushed (and is clean, no contamination of any sort in there), oil is clean and pretty much on the full mark.
Gonna change the thermostat tommorow but i aint sure this is the cause as surely it would run cold if it had failed (thermostats fail in the 'open' position no?)
Any suggestions/help/advice gratefully recieved
