Hi,

What temp is your coolant reaching? I would suspect that the thermostat is stuck open if the temp gauge does not read 90 and then fall back to around 80??

Is worth changing coolant etc if not been done recently too, flush out the heater matrix, thermostat housing/ engine block and the rad and you shoud be good to go Smile

If at first you don't succeed, destroy all evidence that you tried.

I only ever had to flush an old Ford matrix and it was well and truly blocked, presumably Radweld was the culprit. I took the pipes off and Jubilee clipped a hose to it and gave it full mains pressure and it fired some really dirty orange gunge everywhere so make sure the exit is pointing somewhere you don't mind getting dirty.
So where does this bit go then ?

thanks lads ill be having a go at it soon. the engine is getting warm enouth and the heater is warm but i think it could be a lot better. the son in law has just put a new heater rad in his van (ldv ) it never use to put out any heat now he said it burns his legs when its on high.i could do with some of that lol.

Consider bleeding the cooling system prior to doing other works, may save you some grief and expense.

Oh and be careful about using full mains water pressure as you may damage your heat exchanger, mains water is normally above engine coolant pressure.
