Leaking umm heater core (?) I think, Dash out jobby for that.

same thing here and it was heater core leaking

enjoy that job i found it to be a real pain in the **** but thats just me i guess:rant:

Thats the heater core gone.

Have not seen how the Magna's have theirs built, but generally a manufacturer will skimp on the heater core connections and use plastic on the heater core, over time, heat destroys this, they crack and leak.....

This requires the removal of the whole dash - enjoy :)

Oh great can this affect anything to do with the aircon? how much this job at a mechanic?

my mechanic offered to bypass it.
so now i have no leak, but no heater.

air con still works fine.

wtf nice in winter
Just take the dash out....its just a few screws and bolts nothing magical

Its a common quick fix to bypass the heater core......

You have to worry about things like airbags, air con controls, etc etc

Its not that hard, just labour intensive.

What do u mean by u have to worry about those things?

Worry,

As in take care when removing the dash, aircon controls have linkages, airbags im scared of, even with the battery disconnected :P

As I said, its nothing hard, just labour intensive.

Speak to madmagna about this, although i doubt he'll want to do it again after doing mine lol!

Took from about 9am till 5pm to do, the 2nd hand heater core i bought was in need of new seals so picked them up from mitsu for $2 bucks each (you need two), the 2nd hand core was $75 bucks (just make sure it only leaks at the seals and not anywhere).

We hunted around the wreckers for a bit finding a decent heater core but ALL magnas we looked at had the same problem, it's common. So i bought a 2nd hand one. I think they are about $200 for new ones.

Then it's just a process of finding every bolt in the dash and taking it out, disassembling the whole dash to get to the heater core, disconnecting wiring, taking the seats out for more room, pulling out the piping from the other side of firewall and finally replacing the heater core. It's labour intensive and that's why you'll get quoted big money for mechanics to do it. Best if you get a friend, get the manual and slowly do it over a day or two (if you're mechanically inclined).

The airbags won't blow up in your face or anything, but what happened to me is that the SRS light comes on now (which basically means it might not work in a crash :) ) and needs to get looked at. Not sure how much it costs but i think mal (madmagna) said about 30 bucks.

Hope that helps a bit mate!

lol i know, sucks in winter.

Do a search for the post I did on this a couple of months ago. The summary is:
- it will be the $4 each o rings which press fit into the bolt-out inlet and outlet pipes which mount to the heater core that have dried out and are causing the leak. The heater core will be fine, they rarely leak
- you DO NOT need to pull the whole dash out. That is one way to do it. But it is time consuming and therefore very expensive if you get a mechanic to do it
- I did it (on advice of knowledgeable AMC member) by degassing the air con, pulling the lower LHS of the dash apart (glove box, blower), and unbolting the cooler box inlet and outlet lines. This gives access to the heater core which is removed through removing a single clip and then it slides out to the left. With the core out, unbolt the inlet and outlet pipes, fit new seals and inlet outlet pipes (also about 4 bucks each), slide the whole unit back in, bolt the cooling lines, blower and glove back in. Get the aircon regassed and it's done. A degas and regas costs $180 all up and is something youshould have done every few years anyway. Having the dash pulled and reinstalled is hundreds, plus all the wonderful squeaks and rattles that that brings, and they you'll still need to cugh up for a AC regas at some point to keep it efficient anyway.

Bottom line? Leave the dash where it is...

Great tip, Schnell! I have a musty smell in my KJ - hoping its just pongy air-con ducting, but think I'll pull the carpet back and check for coolant from heater-core - just in case.

Sounds like a crappy job either way, but if I need to do it, I'll be trying Schnell's option!!

That's where you get people like mal to do all the hard work for you (lol sorry mal)
he charged me $150 for it, but i doubt he'd want to do it again anytime soon!

Is the connection in the same place in the AWD as a FWD? Cant make out where it is. Is it in the passengers footwell?

To de gas the aircon and then regas will cost more than just popping out the dash.

We did take the day but to be honest it was not like we were working flat out or anything.

It is the seals that are leaking, just pop out the dash and do them properly, Stuff reaching up under a dash, removing the aircon box, then booking in to re gas etc etc

If you are in Vic pm me and I will be more than happy to do this for you

Well what happens if u leave this problem.? Just get wet floor or somthing

ok guys, im not gona make a new thread coz i have a similar problem.
Every time i wash my car the floor on the passenger side become very wet, took it to mitsu n they suggest 2 change the black plastic cover underneath the wipers n i did change them but still leakin then they suggest 2 change the windscreen, n i did but still leakin... Any1 wld be able 2 think of sumfin? Dunno where 2 look...
Anyone??
Thx in advance

HRD2GET,

Seems like a different problem, but can't deny that it could be called a "Weird Leak".

We prob need a bit more info -where is floor wet? Can you see water trickle anywhere?

One thing that comes to mind - is the weathershield rubber around doors properly seated in its channel - a couple of the TJ's in our family have door rubbers falling out / maybe shrinking back a bit - in our case its wind noise and dust entry is the worst symptom. Has happened on a drivers door and a rear passenger door. If that affects your front pass door, it might let water in to footwell.

Otherwise, try to track where water comes in. Perhaps remove lower dash trims and footwell trims to see better - if water seems to come that way. Perhaps remove A-pillar trim and see if its coming from higher up? Try squeezing yourself in while someone "waters" the car for you...

If you've had both the windscreen and those black trim-panels nr wiper arms replaced, you'd hope they got a good seal on windscreen opening. There are a few openings in firewall, for heater pipes, air-con etc - your not pressure-washing that part of engine bay by any chance?

Has the car had any bingles which might have popped a panel weld, or opened up a seam?

Is it definitely only when car is washed? What do you use to wash car - eg: garden hose or pressure washer?

Sounds like you've invested some time and money so far - think I've run out of ideas unless you can do a bit more CSI-type detective work!! Good luck.

Mate, I seriously hope that in future when you type a question you can please use regular English. Reading your post seriously did my head in.

Now to the problem, under the front guard there are a couple of grommets, these can fall out. Also check your fire wall to make sure where your wiring etc is that all the grommets are sealed and also check that someone has not run something through the fire wall and left a gap.

Also if you search, there is a previous post about these grommets as others have had this issue before

Mits are tugging them selves as if your screen was leaking you would not only get water on the carpet but it would be easy to tell as you only have to remove the "A" pillar trim to get to it and see. They do not know so only make dumb guesses

thx heaps mate that will explain things coz i only noticed that after my audio gear was installed he run few wires to install the amps underneath of each seat
i will get it checked tomorrow n see how it goes...
and i was at work and using my phone when i typed the question :rant:

I did mine myself, pulled it apart on a Saturday arvo, put it back together Sunday morning, but that was just me being slack, I found the longer I left it the more coolent smell I got in the car, the glycol was gassing me and making me feel sick when I was driving. So don't leave it to long.

Yeah it becomes overwhelming, and a sort of mist comes out of your vents, or at least thats what happened with mine. Not sure if it's very safe to be breathing it in either! You'll also be having to top up your coolant more often than normal due to the leak. And if you leave it very long maybe you'll flood your electronics. We found dry coolant all over the place, including the ECU (i think? Area under the headunit), thank god it's got a protective sleeve though.

Yeah, that's the biggie if you leave it too long - possible damage to electrics. Not nice
