Heater matrix leak - Page 2

welshphil7805 · Jul 12th, 2019, 17:51

Well after buying two Orings from my local friendly Volvo garage I hurried back to the workshop to fit them. My god what a pigs ear of a job! You have to remove the two quick release connectors in the engine bay. Volvo decided to bury them deep into the firewall. Eventually I removed them. This gives you some movement on the metal pipes under the dashboard. My main problem was that you have to slightly bend the aluminum pipes to get the new Orings on. This causes slight miss alignment of the pipes when it comes to refitting them. No room to move and needing three hands meant I was there for nearly three hours fitting them! Aligning the pipes, pushing them together and trying to fit the clamp all at the same time. Nightmare. If it leaks again I am going to do the Ford thing and putting a rubber pipe sleeve on them.

Well it gets worse. After busting a gut fitting the new Orings
I have now found the heater matrix is leaking!
So the sage continues...........

Oh sh*t.

That one isn't nice - You need to remove a lot of dash to get to the heater core

OP - Did you ever get this sorted?

Still got a minor weep coming from mine, it's getting progressively worse as the weeks go by so I'm going to have to bite the bullet and sort it soon.

I have to keep the AC on pointing at the windscreen all the time since it fogs up with evaporating coolant if it's off.

Annoying really, because it's not even dripping, just a tiny amount weeping around the O ring.

I had this when I bought my V50.... One container of K Seal later and the leak stopped never to leak again in the three years I owned it.

I tried the K-seal, did nothing for me, which is odd because I have a tiny tiny leak and people rave about the stuff.

Hi guys
Yes I did finally fit a new matrix and it wasn't without its problems. I just couldn't get the new orings to seal even with new clamps. In desperation I cut the ends of both pipes and fitted a small length of heater hose and jubilee clips. It's a more secure fitting as far as I am concerned so not a job I would want to do again.
