Looks like I may have a hole in the heater core on my NH Pajero water comming into the cabin on the passenger side. Does anyone have any info on how difficult is to change the heater on this 4wd and are they expensive. Any advice would be greatly appreciated. Thanks..

Maybe not your heater core! 2nd GEN Pajeros are notorious for vents and drain pipes being clogged up with gunk and then leaking on to the passenger side floor. Give them a good clean out then see how you go.

Dave, Don't think that blocked vents are the problem wish it was that, have not had any rain when the problem appeared. Hazza

Harry, You HAVE been running the A/C though, haven't you....

Most common problem in all makes is that dirt blocks the A/C condensate tray outlet or the rubber hose is displaced by big feet, leading to the release of the water inside the cabin, usually at foot level.

It is not related to the air vents coming into or going out from the HVAC system. Usually there is a small rubber hose (1/2" dia or so) that will discharge through the floor coming from the HVAC area.

Have a look under the vehicle at the firewall/floor area for a "dangly bit" of hose, or inside for a bit of hose that seems to go nowhere. Reposition it and make sure it is clean with a cable tie passed up the insides to dislodge the dirt.

Changing a heater core in most vehicles is one job you really do not want to do. It is usually the first system instlled in the dash area and that means the last to come out. Bank on a couple of days to do the job, +/- 3-4 nervous breakdowns, 2 mariages and 3 divorces, a career path destroyed, and half a dozen admissions to a psychiactric hosspital....that's after the police have arrested you for running down the street screaming obscenities...

Thanks for the info Gary what you explained seems to make sense I have been running the A/C, as somebady else said about the coolant if was that it would have its own distinct smell which this does not and you rigt about nervous breakdowns and mariages problems, I check out what you suggested.

I am making the assumption that you have coolant (red/pink or green) in your cooling system.

If it is the heater core, it will pee out red/pink or green 'evil' smelling coolant, and should be hot to warm.

Now if the fluid you are detecting is clear, cool/cold then it is the aircon or a leaking windscreen or something similar.

Once you have determined/figured out what the problem is, we may then be able to assist you.

Otherwise just wild guesing
