Yeah I'll try get onto it this weekend. Luckily it Wont be moving from the garage and has only been getting started up a little every now and then. Just drained and refilled the coolant system a few month ago. Frost or something must have caused the issue.

i've always found that if the matrix leaks the windscreen will fog up when the fan is turned on, else it would be the hose.

Have not noticed it fogging up yet but i will try that out and see what happens thanks :)

The way the pipes are run inside the car is very poor design. If one of those pipes were to fail when the car was going along the hot coolant would scald the passenger's feet and the windows would immediately steam up.
On my 'S' i use steel braided hoses inside the car.

Where do you get them Peter?

[Cooperman]

Demon Tweeks should keep it in stock.

Thanks Peter, helpful as always

For competition the regs state that any pipes carrying hot fluids through the passenger area must be either solid metal-walled tubes or steel braided flexible material and must also be marked in red. Makes sense really.
Imagine driving on a special stage at over 80 mph between the trees and a heater hose splits. One scalded navigator and a crashed car because of steamed up screen.

Or anywhere really.

 

The burns would be horrific

Yeah actually now you mention it definitely will be changing to braided as i wouldn't like that to happen to me or anyone. Especially if there is a wee one in the car or my dog etc. Will demon tweeks know the required size by the car or do i ask for a specific.

Hoping to get up and have a look tomorrow see if i can source the problem. Was thinking usually for finding leaks i use a small amount of fairy liquid, will these be okay considering it can get into the cooling system? or would i be safer just doing it the normal way

You will need to know the inside diameter of the hoses. There were 2 different sizes used over the years.
All you should need to do is top up the coolant and run the engine until it is up to normal working temp. Then check the pipes and inspect around the heater box for wetness.
It's a good idea to change the hoses for braided ones anyway.
Good luck with the job

Id just get a box of tissues to locate any dampness.. wipe and dab keep examining the tissue for signs

Ahh yeah never thought of that. Will try that method out.

[Helter_skelter]

Had a good look today, hoses seem fine and can't find any leaks. I'm thinking maybe it's condensation? With the garage being a little wet?
Lifted all the carpet and dried it all and left the carpet off to keep an eye on it.

Another method to use is talcum powder. Dry everything off thoroughly then sprinkle underneath the pipes and heater.
