Technical Heater matrix

[Ryanedgeworth89]

New hose has arrived and has a oring seal inside. Will fit to van when i can and hopfully have a postive update when done. New head gasket was fitted this time last year along with water pump & belt, 2 new injectors, set of glow plugs, new exhuast inlet and new valves. It only went to them as 2 injectors had failed and was seized and they are the garags everyone eles uses for seized injectors. Garage that done all that work are the ones that checked everything over saying it looks like heater matric and everthing eles was working as should be pipe come off on the way home from there!!!

Put some lube on the hose before pushing it on to save the new O ring.

Plus check de-gassing tubes clear
, refill coolant following correct proceedure, check heater works when engine warm then get sniff test carried out.

What lube you recommend?

Hi Mike,
Did your heater matrix problem cause so much pressure in cooling system a pipe burst off radiator? Like the ops van.

No, it didn't. No pipe burst. It was just clogged and coolant wouldn't pass through.

What lube you recommend?

Just some grease. Vaseline is fine.

Id disconnect the heater matrix hoses in the engine bay and stick a garden hose in one side at a time to see if water comes out of the other one.
Id also disconnect the smaller coolant hoses and check they are not blocked as already suggested. If its a 2.3 you have one that goes to the top of the radiator by the left headlamp, then one near the back of the engine on by the cam cover/ PAS reservoir side.
The one heater hose has a bleed valve in it you should open to allow the air out the system when filling it back up with coolant.

Yes got the 2.3 as you look at heater matrix hose from engine left hose(drivers side) is hot other side with bleed screw is cold. Had tried bleeding and nothing worked. This is all before hose come off from top rad

With engine not running and cold-The coolant level in the expansion tank has to be higher than the bleed screw to get any flow out of bleed screw.

Check both small tubes to expansion tank completely unobstructed-can be blown through.

Be very very careful the bleed screw when hot will seal even when loosened ,until a point where an burst of scalding coolant erupts under great force. Do not loosen bleed screw when engine hot.
The header tank cap is similar do not loosen when hot.

Both small tubes are clear. New hose has been re connected. No coolant leak when topped up. Got to a constant flow from the bleed screw. Will leave over night now and check again tomorrow before starting van and get it up to working temp. Fingers crossed!

Great , no need to wait until tomorrow unless you wish too. Start up , warm up fully then leave over night and check when cold tomorrow morning.
