PostSubject: Leak in Rear heater (hose) : Water pooling in vent   Wed Jul 13, 2016 7:09 am


  • Hey everyone. Well i got my 1st Supercustom and are loving it. One problem. Noticed a bit of coolant puddled near my back wheel (drivers side) and then the coolant light come on.

    After topping it up with water (just to locate leak) and looking around the radiator, i slheard a drip(s) and the lake of coolant/water pooling in the rear bottom heating vent.

    So im assuming a hose is gone. And itz leaking to the outside of the van.The fan still blows.

    So my question is...what is the best way to get in. And it should be just a hose replacement right..?

    Also...what is the black round thing above the vent. (Bottom photo on side)

    Thanks.

I don't have this rear heating so I'm not sure where everything is. But can't you remove th panel and see what is leaking with a flashlight?

Yeah im guessing thatz the go. Just have to figure out the best way to go about it. Maybe im just being too precious with my new toy...hahaha.

The side seems to be made up of 3 panels...so im guessing top 1st.

I'm sure (memory may be playing tricks and mixing up Toyotas), that the rear heater matix is behind the driver seat in the sort of hump.
Hope this helps.

I did open that hatch behind the drivers seat up. But there were no leaks visible there. Will take another look though. Just identifying what im actually looking at.

So somewhat got the panel off. So ive identified the fan blower (working) what is beneath it..? Reseviour tank..? This seems to ne directly above the leak. Again..just got to sort out how to get it off...im assuming the whole blower has to come with it.

Im not sure. But the part number could give a description.

But I guess there is no other way then to disassemble it.

Found the source of the leak...not hoses. Heater core. Wonder if a recore can happen...?

Again..guessing that i take the outside hoses (of the van) out so the whole unit slips off....

Fun times..!!

Re-core should work.

Sounds like you can get it recored, or replace it with a 10mm or 15mm copper pipe if you don't think you'll need heat there, as I'm sure the heat would travel from the front, especially with the roof blowers on.

I suspect quite a bit of piping in the SC is redundant for the UK TBH.
