Is it leaking at the joint with the metal pipes?

[Jeff Turbo]

They don't normally leak except at the joint

[Jamie Hutchings]

Hmmm not sure will have to have a proper look

[Jamie Hutchings]

Seems to be slight weep from where the pipe goes into the matrix

You only need a gasket for that. You'll need to remove the pipes from under the dash, pipes connect in the bulkhead and run through to the matrix. You'll need an Allen key to separate and get the metal pipes out. It's the same gasket as a rover sd1 or make your own. Later models used 2 O rings but they perish and rust the pipe where it meets the matrix. Not a big job, just awkward

Thank you could I also pick your brains on why the car might be running a bit warm too it's a 1.6 auto, We've flushed the coolant system changed the thermostat doesn't appear to have any signs that it's a head gasket and doesn't appear to be any water leaking from water pump

[Jamie Hutchings]

Also that can be done without removing the dash or gloves box?

Is the fan kicking in when it's getting warm?
You do not need to remove the dash to remove the heater pipes from the passenger footwell. If you look there you'll see how to remove, and as per my instructions on your earlier thread

[Jamie Hutchings]

Yeah fan kicks in
