heater help on mg

[richi]

Right I have a mg zr whilst my nova is being fixed up and the heaters have packed up, traced it back to the heater matrix inside the car, I feel the warm pipe going in but the pipe coming back out is cold,

Should I take the heater out on see if its blocked up with **** or is there another way without pulling the dash apart thanks

Can you get to the 2 pipes behind the engine block of you can pull them both off, attach a hose pipe to one of the sides and turn it on full chat, job done lol

Check that the valve on the engine side is open, also they have a fault with the heater cable bending so the blending flap is not shutting the cold air out (I have this problem on my rover 200/25 bubble run around)

Mave a look on here

Thanks both Royston and chris, read the article and the head gasket had gone so sounds like the matrix is blocked up with all the mayo, so I just disconnect the 2 pipes and flush water thruough it hopefully this will work thanks

lol read the first sentence & thought headgasket.

If the head gasket is done properly, they are great cars!, must use good quality gasket set (paynes, with additional shim gasket) and last

I've done 2 now, not experienced a matrix issue myself

Its worth a shot and also alot easier than removing the heater matrix if it cures the problem.
