99 P38a Thor 4.0 V8
Hi, having issues with my P38a cooling system, prior to carrying out a flush and coolant change today it would get up to about a third of the way across the temp gauge and move no further, heaters all functioned as they should but always got that water flushing sound come from heater matrix area when accelerating and a consistent leak from what I thought was the thermostat.
Investigated further this morning and the leak appears to have been coming from the metal elbow pipe that the top hose connects to which then enters the inlet manifold, took off and cleaned mating surfaces, added a touch of sealant and that all seems good now.
Flushed the cooling system while I had everything off including the heater matrix and all came out clean, cleaned the radiator to expansion bleed pipe, refilled slowly with new coolant with the expansion tank in its highest position, let it run up to temperature and now it gets steadily up to half way on the temp gauge but will only blow luke warm air out the vents although the water flushing sound from the heater matrix has gone, I should point out that the radiator bleed pipe is blowing an almost constant stream of bubbles and coolant into the expansion tank(It did this before the coolant change), also after running up to temperature the expansion tank pressure is normal.....Any ideas where I'm going wrong?
Cheers
