hi all new to this forum.
I have a Sprinter van 312D 1999 Turbo diesel 2.9ltr in Australia.
Recently this van had cooling system symptoms.The temp.gauge would operate normal (heater would work),then gauge would rise (100-115 deg celcius) , although heater would not get hot with heat setting to full heat.
I thought for sure the THERMOSTAT was the problem(sticky).
I proceeded to get a new thermostat and thought while at it , get a new water pump also.
Installation of both these new items has not fixed the problem!!The water appears not to be circulating up via the header tank.The lower hose(thermostat hose)is getting hot , and I would assume that the thermostat is opening up.
But still no circulation to the header tank. The header tank stays cold , whilst the temp.gauge is showing 90-100 deg.celcius.
Where do I look now? - heater core , heater tap , is it the heater controls not working?? Do these vans have any electrical input which could affect the cooling system. (relays,elec.valves etc etc). Any advice appreciated. The radiator is only 8 months old and was brand new from my last cooling issue.
On installation of the new items , I filled the engine via the top entry point(top hose)to ensure coolant within the engine , currently the systems has about 7 ltrs of coolant added,header is at max.level.I ran the engine until 90 deg was achieved on the gauge , with the rad.cap off , to prevent air lock.Header stayed cold.HELP!?
Any help please mail me.
