This isn't a job I ever want to do again. I just know I will have parts left over. Looks like a bomb went off in my interior!
The new core I bought is twice as thick as the original, but it still fits just fine.
While I was blowing out the inside of the box after washing I found a spring laying on the ground. I surmised that it might have come from one of the blend door shaft wells in the bottom, but if so that means I lost one of them.
Anyone know if there are springs on the blend door shafts?
Sorry, can't help with the spring. It's been too long since I did mine. However, lucky guy that I am, I get to do it again! The aftermarket heater core failed. I kept the original so I had that checked out and resealed. The shop said that the tank wasn't fully seated on one end which is why it leaked. I won't put an aftermarket one in again, hopefully they have gotten better. Years ago when I replaced mine, I had the old and new together and remarked what a beautiful little radiator the original was and what a pile of excrement the new one was!
Replacing a heater core is one of the worst jobs ever. I'm so looking forward to doing it again! My 01 Bleep Cherokee was actually worse than the truck.
Hope I never have to do that again! I have heat now, but the heater control valve isn't closing. All the blend doors are working though. Must be a vacuum leak in the controls somewhere.
Was able to throw some weld on the top of my clutch bracket gusset while the dash was apart, it's a lot more solid now.
Difficult/aggravation score for this job, 8.5.
When I swap this chassis you my 1941 WC I will use the divorced heater box that came with the '41 and hide the A/C ducting up under the dash.
Well, that looks like a nasty job. I have an idea for you guys to never have to change a heater core again and I think that you know what it is. Yup, stop putting water in the antifreeze. Surprised? Honestly, I have not had a failure of any of my cooling or in this case, heating, systems in years. I mean like thirty years.It's not like the water in Phoenix is not problematic, because it is heavily mineralized and will cause galvanized plumbing to plug up like a coronary artery in just a few years. ok, I'll crawl back into my hole now ...Mark
I want to run the magic waterless coolant but it is expensive.
Maybe, but a 14 dollar gallon of cheap ethylene glycol is about 13 or 14 dollars, times 2.5 IIRC the capacity, is a heck of a lot cheaper than the torment of that job you just did. Not to mention the cost of the heater core, probably not too much. I haven't changed my coolant since 2013 when I did this thread:
It wasn't even necessary then and I reused a gallon of the old, IIRC. It was years prior to that when I had changed it before. I think that it is a conspiracy of the antifreeze companies (I'm looking at you Prestone) to keep things failing on American's cars. In collusion with the auto parts industry of course...They're all around us ...Mark
