Heater maxrix

Recommended Posts

I think the heater matrix on my Lipo TDI is on the verge of getting go, unexplained condensation and a small of glycol. How big a job is this, has anyone done it as a job, help appreciated

No puddles of blue anti freeze on the floor so far from certain that it is a problem, my grandson cleaned the interior too so the smell might be the crap he spayed on the dash? Is there any kind of test that would confirm it?

Does the coolant level drop over time? Should be pink or purple antifreeze too- the blue stuff will actually corrode the engine and make things worse.

I've never changed one on a Lupo, but heard horror stories about how much work it is. Apparently, when building a new Lupo in the factory, the first thing to go down the line after paint is the heater matrix. Then all the other bits are assembled around it. It's like trying to get to the earth's core.

Maybe @Rich has some good ideas if it does need to come out.

If it has to come out then it has to come out.

It is dash out but what you could try is a bypass and are if that is actually the cause of the water loss.

If its any help - a golf is about a day to take out and a day to go back in - so kiss goodbye to a weekend!

It should be a little quicker with a bit less stuff to worry about in a Lupo.

As Rich suggested you can by-pass, but that's not ideal going into winter.

having space to put all the stuff as you take it off is a must

Pressure test - pressurise the system, it should maintain pressure, if it drops you have a leak

No sign of a leak in the cooling system at all which is a good thing and thinking more about it, it would be red fluid in the footwell not blue or green, so far neither so it may be just the wet weather we have had. Its also got a sun roof so the drains need checking too
