TSRM section for heater core?

The dash really isn't THAT hard to take out. It's getting everything else out of the way that's hard :rofl: For instance, the driver's seat...
Oh, targa helps too just so you have more room.

Only kind of. I can verify that the leak is under the dash, but there are at least three pieces under there, and it could be any of them... in theory. In reality, if the extension hoses never seem to fail, it's very likely the heater core.OfnaRcR4;1844223 said:
Ya, it's only a few hundred $$$, and it's a lot of trouble saved, so that's the route I'll take. Why try to shortcut a car that I'm already so deep into? And worse, this is one of the biggest pain in the ass parts, so I'd rather change it and be done with it for another 25 years.Supracentral;1844237 said:
Agreed... although the Recaro seats sure do simplify it a lot, and the targa helps a bunch more...Poodles;1844239 said:
By the way, anyone have any experience with aftermarket heater cores? They are nearly $300 from Toyota USA, Rock Auto carries them for $50 - $110, depending on brand.
I bought mine from Napa and it is noticeably lower quality when compared to oem, I have it sitting on my desk I can snap some pics if you want. The section of the tube where the extension pipe slides in appears to be oblong, I highly doubt it would seal properly with the stock O rings. I will have the tubes soldered on to be 100% sure I have no leaks there. The fin count and row counts are lower that oem, and overall size is slightly smaller than oem. If you live in a place where heat is a necessity I recommend an OEM core. If you live somewhere like where I do where the lowest temp of the year is in the 30s at night time it shouldn't be a big deal.
Oh ya, and the aftermarket is copper whereas the OEM is brass.

The core on my 5.0 from a decade and half ago leaked. Dash removal was a part of the job, at 9.5 hours R&R. Same thing, coolant in the cabin. Only worse. Some came out the defrost vents. Blah.

Back in the late 80's, I had a core in a heavily modified 5.0 fox body Mustang burst during a full throttle run while I was in the passenger seat...
2nd degree burns from the knees down. The passenger gets the worst of it in those cars.

I bought one from Rock Auto about a year and a half ago. It was of Mexican origin and looked just fine to me. My original core was wrapping in sticky-backed foam, which was missing on the new one.
It took me some effort to find foam to stuff around it that would take the temperature of hot coolant (found some polyethylene foam at H.Depot). I bought new extension pipes, o-rings, and clips from Toyota, however. The ends of the pipes where they poke into the engine bay get some abuse over the years, so are worth replacing. I also wrapped the o-ring joints with self-sealing tape as cheap insurance against leaks.
Ugh... I remember when driving to AZ, I discovered that the hose into the engine bay from the driver side hasn't been pushed on far enough. Car slowly leaked hot coolant into the cabin drip by awful drip. This was in late April, where temps are already getting into the 90's in that part of the country. The cabin temperatures were reading above 50° C, which works out to around "holy shit it's hot in here" when converted to Fahrenheit...Nick M;1844301 said:
Random question.. would a blocked heater core cause low airflow out of the vents like on other cars? I'm getting an infant exhale amount out the vents.
No, that is more than likely the blower resistor. Lucky for you, it's cheap and easy to replace.OfnaRcR4;1844406 said:

Toyota does have instructions for taking out the dash in the TSRM, but not specifically for the heater core.

I wish it was that. I under exaggerated the amount of air it puts out, it's just so little compared to my 91. I think i can now blame it on the noisy auto zone blower motor i replaced the worn out stocker with. I'll have to swap them out and see i suppose.

Resistor, blower, or very common if the dash has been messed with, missing sealing foam for the ducting.

It took me 5 blower motors from schucks/orielys to finally get one that doesn't sound like small jet engine! Good luck !
