just a thought, if the head gasket is to blame, would there be bubbles and expansion even when cold ? with a permanently opened thermostat i mean

As I said before I have had the head gasket done or rather head gaskets a few months ago and it’s been running fine but it is bubbling with the Off and pushing water out or was until I forced water through the matrix going for a drive now see if makes a difference

Wondered if its worth getting a cylinder pressure tester to see if any air comes back through water system? I have a compression tester

ok got you, I have replaced that hose at the plastic T snapped. I will force feed the matrix system with water today as well, see what happens. I also ordered a brand new head gasket test kit, should come today

Which one do you call the bypass, the one feeding down from the top hose, or the one feeding the thermostat from the heater matrix ? One thing that is happening, is the heater sometimes goes cold

HUmmmm a possibility, but the two smaller top hoses of the thermostat are slightly different sizes, but I will check today Thanks

Thanks for that, I have an old thermostat and I have managed to stick it open, and the temp gets up to normal (about half way on the gauge and stays there, not ideal, but its proving a point to me at least

Brand new rad fitted todat

I have replaced the expansion cap, not sure what is meant by "NOT POSSIBLE ON THE THORE ENGINE" Confused as to why the water should be cold on the bottom of the rad ? was not warm at all just like cold water, surly, if the thermostat is working it should be a little warm I will back flush the...

The bottom of the radiator is cold, the top is very hot, top hose to the thermostat was hot, bottom hose is cold, when i took the top hose off the pump side of the thermostat (top of Thermostst housing) it was very hot, when I took the bottom hose off the thermostat it was cold ??

OK update I have changed the viscous unit, the water pump, thermostat, and now a new radiator, and the things still boils I did a test on the thermostat and it opens and it says on the unit at 82 deg I have had a cylinder head test done with the blue but no indications, just stayed blue The...

yes that next is the next job Monday, pump water into the top, see what flow at the bottom, I presume that is the way, might just order another one anyway.

My V8 p38 petrol 51 plate started overheating for no apparent reason, I had the block tested with the blue solution, no leak into cooling system detected, so I changed the pump, old one was ok changed the thermostat, changed the expansion cap, changed the Viscous unit, all to no effect, still...

People keep saying it wont run right unless I do, Also What lambdas do I fit to an LPG system, all the ones I find say NOT for LPG ? Thanks M

I am about to fit 2 new lambda sensors to my 2002 4.0 P38 (LPG) How to I reset the adaptive ECU/ Fuel I have the Nanocom Evolution Thanks

I have 2 of these p38’s. And thenother one works fine with the book symbol. But the pots do show an erratic movement. So I have a load of these pots. So will change them all. Thanks. Will Post the outcome thanks mAdbRiT

I have a problem with my blend motors, they don't work, So I have taken my blend motors and distribution motor off the vehicle and connected a 9v battery to them and all 3 work fine in both directions. BUT they wont work via the control panel, I have tried 3 different control panels and I cant...

update, its a week since i have paired the two motors, and its all working great, thanks to all that helped, really appreciated MadBriT

there is no voltage to the motor in any way, with this control panel or the new control panel, plug is ok wires were ok, SO I have cheated ...... I have connected the left motor power wires (brown and black to the right motor brown and black wires (Brown to black and black to brown as the...

ok thank you, so i need one with a pre amp and a conversion plug set
