Thread: Leaking heater box

Rusted matrix? If your 'duckbill' is blocked it can collect water in the heater housing and rust out.

Given the green colour, pretty sure it's the matrix. I'll order another one this week.

Hi you don't say what 130 you have . Once the core has gone , It's not serviceable . The good news is there not very dear to buy $ 70 I'm talking pre Puma . The bad news is you have to take the heater box out , and if you have A/C you have to disconnect that , to get to the heater box fixings . The bolts are up under the footwell . don't be surprised if there rusty . I replaced mine a few months back . I thought It would be an easy little job , It turned out to be a bit more than I expected . I was pleased when It was done . Just a tip fill it up before you re connect the heater hoses !!.. Jim

Hi Ranga

Mine started doing the same about a month ago - two days before going away on holidays.

I just went to Enzed on Nudgee Road and picked up 3/4 inch (20mm) brass fittings to bypass the heater - two x elbows with hose tails and 1 x union to join the two hose tails. Don't forget to use thread tape/sealant when joining fittings. Cost me $40.

Heater was never that great anyway. Just carry some fire wood and get a fire going on the passenger floor

Cheers
Andrew

Hi Andrew , like you when mine went I bypassed It . My fix was I had a bit of dowl about 18mm dia . so I cut two bits about 50mm long plugged the hoses , put two hose clamps on . Tha fixed It till I got a new core !!.. Jim

I wouldn't recommend a standard heater matrix to anyone, the new one I fitted only a couple of years ago has just started to leak again, an Allisport full alloy matrix is the only option in my opinion, not at all cheap but reliable.

Holy **** - ~$500 delivered! Think I might just chance a steel one.

Yes definitely getting up there, you would probably get six or seven standard ones for that price but for the hassle of the job it might be worth it, I had a ***** of a time getting the heater box out last time! Maybe there is a trick to it that I haven't learnt?!
Its the plastic end tanks on the standard ones that are the weak point I think, my first one cracked at the top and the current one appears to be leaking from the bottom plastic bit (which I can see through the vent I have cut in the LH side guard), yet to pull it out yet though...
