Hi,
I have an issue with my Partner 2hdi, the engine temp gauge reads approx 82c most of the time but will drop back to 70c for 10mins or so & then back to 82c.
Occasionally it will suddendly jump into the red & the stop light on the dash comes on, then within 30 seconds it'll fall back to 82c. Once when this happened I stopped ( engine off ) quickly to check, the top hose was warm & the rad fan was running, then the top hose got hot & on re-starting the temp was 82c.
The water pump was replaced 4 weeks ago along with the timing belt when I first bought the van, so don't know if this was happening before that.
I've replaced the thermostat but that hasn't made any difference.
I wondered if it may be an air lock, but I can't find any advice on bleeding the cooling system, opening the bleed valve on the thermostat housing releases coolant but no air.
The heater works OK.
Any ideas ?
Many Thanks.
