Temp keeps rising to red when going up hills. Don't want to blow head gasket. It's just had new thermostat and water pump and auxiliary belt so unsure on issue. It's a 300tdi discovery

check that rad int blocked and that it also has cooling fins both will cause it to overheat also bleed rad with engine warm and running to get any air out of system.

few fins missing on right of rad and bit on mud on lower part of intercooler and rad. would yet wash be ok to clear mud

Has it been bled properly and was it overheating before you changed those parts?

 

[shreksta]

It was overheating so changed parts. Mate bled it and no sign of leaks just rise in temp at hills etc. I've washed mud off with hose pipe so will see how it is over next few days.

:nothingtoadd:Still had overheating under load and up hills so replaced radiator today and serviced it so fingers crossed. Took a few bleeding attempts .

how so 300 is easy to fill just undo bungs and fill

Airlock in system think around heater matrix

True, but that causes a cold heater, not over heating. My money is on the radiator being blocked internally

I had this issue and after a pressure bleed it eventually took and stopped being an arsehole.... well for the time being!

Replaced radiator at cost of £132 for britpart and has resolved issue
