Thread: TD5 heating up, blowing white smoke

Doesnt sound good.
Check to see if the eletric booster fan is running all the time when the motor is running with the climate control off.If it is the ECU has detected an overheat and will run the fan automatically till the fault is cleared.
The power drop also indicates the ECU protecting the motor.
At running temp CAREFULLY squeeze the top radiator hoses,do they feel like there under alot of pressure???? Indicates exhaust gas pressurizing the system.
Put a small plastic drink bottle over the drain tube on the header bottle,monitor it for spitting coolant out.It could be air pockets forming in the cooling system are masking the loss of coolant.
Other possible causes,stuck thermostat or faulty radiator cap.
Unfortunately head gasket failures are common on the TD5,mine has been done.
Goodluck

Thanks mate,

Turned out to be a stuffed viscous fan. Replacement supplied and fitted by AMV for a very reasonable price.

Fingers crossed that's the worst of it for a while!

Sorry didnt mean to hijack the thread.

Mine done this. Still weeping coolant eventhough I put two clamps on the top hose to engine. What does it mean when you said "Indicates exhaust gas pressurizing the system" ?? Do you think there is still air pocket in the system? Thanks

I could see how a stuffed viscous fan could cause high temps on heavy load such as when you are towing - that makes sense. But that's not going to be the cause of your heater issues! Are your brakes working correctly? I wonder if the D2 has vacuum operated heater flaps - perhaps you might have a vacuum leak there.

Hmmm ... not sure. In any event the heater now works - maybe the ECU was shutting something down with the higher temps? Before the repair I had noticed that the booster fans would stay on for a minute or two after I shut off the ignition ... I assume these were disspitaing the extra heat but perhaps the system had gone out of whack as a result?
