Hi All,
A quick Sunday night puzzler for you all ..
My Discovery 2 TD5 auto is really overheating if I go over 3000 RPM for an extended period i.e. up a steep hill. Now I have only just bought the vehicle and have had to do some work on it which Ill list but this problem has really got me stumped!
I replaced door locks, wiper assembly, auto gearbox oil, both oil filters, fuel filter, air filter and top branch hose (the one with the air bleed valve) and the dreaded WATER PUMP.
Ive been bleeding the coolant hose and holding the expansion tank above the height of the bleed tap until only fluid comes out. Next morning (or on the road when it over heats) I can still get more air out of it!
Im pretty sure that the head gasket has not failed as the expansion tank doesnt bubble and there is no oil in the coolant or oil itself. Overall the engine runs like a dream and doesnt hunt however it seems to need to rev high -2000rpm for 15-25 MPH- but perhaps thats just the way the TD5 is set up
So, do I have a leak somewhere? I havent seen any water on my drive.
Is the radiator shot? My 300TDi died this way
Have I done something wrong with the AUTO fluid change?
Could the heater matrix be at fault? The heating is intermittent?
Or finally does it just take ages to get all the air out of a system that's been drained?
Any thoughts before I bite the bullet and take it to a dealer would be greatly appreciated
