Mk1 1600 thermostat housing leak

Postby georgefromdevon » Mon Oct 01, 2018 4:17 pm

Noticed that my little na6 had no coolant in so filled it back up but also noticed that it's leaking at an alarming rate at the t junction, looks very badly corroded.
Anyway I looked online and the housing is about 70-80 and it's a nightmare to change apparently so I was thinking about pulling the steel tubing from the aluminium housing drilling and taping an m8 hole and screwing a double banjo bolt in instead
Anyone else tried this fix for a very common problem

Cheers George

"I looked online and the housing is about 70-80", yes that is about right and you have to change the "O" ring and if you use a cheap one that is too fat you can crack the fitting so get a new one.

It's a nightmare to change apparently, explain why it is "nightmair".

No I bit the bullet and bought a new component. I will have a look tommorow and see if that seems a runner.
