Help Support Nissan Navara Forum:
Seems I have a leaking heater core (coolant on passenger floor). I removed the glovebox but not sure what to do next. Has anyone replaced one? Any help (photos etc) would be much appreciated
what are your symptoms mate? i have a dribble of coolant coming from the floor air ducts, and the underside of the heaterbox has a sweat of coolant on it. the left footwell has a slight damp feel also, so i think its been leaking for a little while (only bought it last week).
i got stuck in there this afternoon trying to find a way into the box itself, but its just about as far into the dash as you can get.
keen to hear some feedback on this one!

Hi Tim,
I bought a small piece of heater hose and bypassed the heater at the top rear of engine for now, helped to stop the coolant stench in the cab and risk of it getting worse. I would like to know if the core can be replaced without pulling all the dash out????

Pretty sure its a dash out job. If you have a look through the service manual it should show an exploded diagram of it
pull the out the dash

Cheers for the info bjs, but Im not looking forward to doing this job, sorta tossing up whether I should bother with it hear in Cairns, but I like everything on my car to work. Any chance of posting some picks of your removal process? Or some idea of where to start???? Any help would be appreciated!

Have a look through here http://www.navara.asia/showthread.php?t=3232
That is the download for the factory service manual. That will help a bit at least...

It's a dash out job. Shit of a job but not to bad if you know what you're doing.
dont get me wrong, i WANT to fix it properly - its just finding the time to dismantle the whole dash
my plan for now will be to do something similar to my fancy-arsed mspaint edit, attached. red hose from heater out to heater in, and plug up the ones going into the cab. i will also drain out as much coolant as i can from the heater box (so it stops dripping into my carpet!)
will let you guys know how i go

job done.
went to SCA yesterday and found something that was close to the right shape. Turns out an old Falcon hose was pretty well spot on.
Cut it down to the right length, and put a couple of fresh worm drive clamps on. Works like a charm!
Now to flush the coolant from the heater box and drain it.

Hey guys
Was wandering how every one went with their heater core problems.
I currently have had mine by-passed for the last 6 months and am keen to sort it out before going away at the end of the year.
I was wandering where everyone had sourced their parts, I priced one from Nissan and it was over 400. Also has the unit changed over the model changes was thinking of getting one from a wreckers, a look through a pdf workshop manual does not mention any changes as far as I can see.
Any thoughts on how other people have dealt with this will be great.
Thanks
