Evaporator Core found for AC but not DC. Are they not compatible?

    While looking for parts and prices to renew the A/C system, I noticed the denso evaporator is only for the AC. Screenshot_20250709_124515_Chrome.jpg Screenshot_20250709_124443_Chrome.jpgIs there a evaporator for a DC other than buying the $1,200+ Evap Core and Case Assembly?

    DC has a bigger radiator than AC. I would guess same for Evap Coils. Unless punctured or fins damaged this is not usually a replaced item. Normally hoses, o-rings and compressors are what need replacing.

    Using a random 06 DC VIN I found and plugged into the epc, your genuine OEM part number is 88501-0C060. I have found that it is discontinued by Toyota, but can be had in the aftermarket.

    Condensor or evap core? The one at the radiator support, or the core that's in your dash?

    You and I have the same trucks, different cab. Same year, drivetrain, trim, engine, etc. but different cab. So our parts are essentially the same, minus the radiator.

    I always tell everyone to look up your parts using the parts finder at www.densoauroparts.com and when I do, this is what comes up - and when I run the part thru RA's site, the evap core is only $119

    But their parts reference is not perfect, as you'll see with the two different TXV (thermal expansion valve) with same part number and different cab type.

    I plan on changing the condenser as well but I was referring to the evaporator. I wanted to keep everything denso. Looks like the desno evap is only for the AC going off the OEM equivalent P/Ns.

    I don't get any cool air whatsoever, even while driving but I have pressure in the system. I want to change the compressor (clutch engages but has a unnatural sound to it like its internally failing), condenser (easy enough), the expansion valve and the evap (need to clean it or replace it might just clean it :notsure:.) I want it do be a one and done fix.

    I am having trouble finding o-rings though. The compressor comes with them and so does the expansion valve. Idk if ill need them for the condenser or evap.

    Any one used these off RA?Screenshot_20250709_160517_Chrome.jpg

    Honestly, if I were you, I'd stop what you're doing, and take it to a specialist.

    There are two times I'll advise people on this forum, strongly, to see a specialist:
    1. When you're having A/C problems, go to a shop that specializes in/only does A/C stuff
    2. When you're having driveline problems, go to a driveshaft shop
    The main reasons being:
    • They'll almost always be able to immediately pinpoint the problem, way faster than any other shop, saving you labor hours
    • They'll usually fix the exact problem, rather than changing out the whole system, saving you parts problems
    • They'll know exactly which parts/suppliers/brands will last longest, so you're not at the whim/mercy of a generalist or chain shop, which'll buy whatever is cheapest and upcharge you
    • They'll have all the proper equipment needed to vacuum/purge the system, refill, and do all the work required, properly, to ensure this repair lasts
    We have a family friend, someone who helped take care of our kids in their earlier years. She had this pop up in her Yaris. A/C kept going out while in the middle of summer, and temps would climb in the car, which wasn't cool for her, and wasn't cool for our kids when they were in the car. I urged her to go to a specialty shop, but their hours conflicted with her, and they were abotu 20 minutes away. Instead, she went to the local chain shop.

    They did exactly what I said, exactly what I warn people about: They flushed her coolant. They replaced her themostat and radiator. They replaced her A/C compressor and clutch, evap core, condensor, drier valve, seals, etc. etc. She had to take the car in twice after that, because it was still having issues, and when it boiled down to it, I looked under her hood, and it was a f'n relay they replaced that finally solved the A/C cutting out on her. CLASSIC.

    Look, you don't need to take my advice, but I assure you, you probably don't want to replace the evap core in the dash, especially if it's not the problem. Doing so involves removing the entire dashboard to be able to open up the housing, IIRC.

    I'd go online and look for "nearby automotive A/C specialist" and find a shop that's got a 4.5-4.6 rating or higher, with at least 2 dozen reviews, and take it in. See if they do diagnostics.
