I thought the 1st gen Alltrac had a dual core radiator? Went to a few CSK/Shitzones/Napa and even to Toyota and they all said it's a single core :(

I don't know man.

Usually if the dealer doesn't show it as being dual core, its not.

I was under the impression they were dual core as well, but wtf?

I know..that's why I'm confused :(

I'm gonna call a radiator shop and see about re-coring my radiator.

The one on my car was single core, but it was not OEM, had metal end tanks...have switched to the ASI rad now tho.

I dunno, according to mafix he said all 165's are dual core.. Ive never owned one so I dunno, I can tell you that my 185 was dual core from what I remember. Just buy a koyo you homo!

That's where I'm confused. He said that, but like half a dozen retailers & dealers said the opposite. I'm looking into aftermarket radiators now.

Maybey I can use my OEM one for target practice...

Would they hold up to the AZ heat though with turbo.... that's the question :)

I know a single core would be fine if I was in higher country here in Az (ex Flagstaff, Showlow, etc) where temps rarely reach 90. Central AZ can hit 120 (it has.. that sucks).

I would go for the koyo if you can get it for 150. You can't beat a aluminum radiator. Heat transfer is better then any stock one you can buy.

.. and you were still overheating!


I'm using a single core radiator that I got from Advance Auto Parts. If you order one for an Alltrac through there you will get the GT/GTS radiator. It's half the size of the OEM Alltrac one.

Me too. In 100* weather here in cali, the highest my temps got were 210* and that's with the crap TMIC.

I'll clear it up for you, no confusion here, I agree with Mafix - all OEM 165 rads are definitely, absolutely 100% dual core, not single core.

That dealer and all those aftermarket guys are wrong. Most of the time they send the wrong 162 radiator to unsuspecting 165 owners. The OEM dual cores have crappy plastic end tanks that rupture. They're junk. With the amount of heat the 165 generates, you certainly do not want a single core rad.

Here's what I researched:
I looked everywhere for an affordable, all-metal aftermarket 165 rad and they simply don't exist. CSF used to make a nice dual core rad for us but that has been discontinued for years now. I even contacted them and tried to get them to make another batch for us but they declined. You still see them on some 165s. Good rads, good price, brass and copper.

PWR made one for us years ago on a group buy on alltrac.net but you're looking at USD$600 plus $75 shipping. Quality, expensive, all aluminum.

There are some Nissen 165 rads in Europe but after you factor in shipping and duty, well, forget it. UK has some too but again, way too much $$$.

That's why I spec'd a dual core 42mm aluminum radiator custom built for us by ASI (China). They are about $210 shipped now. Your set up isn't stock, so I can't comment on how the Koyo one will fit for you. I agree, they are most excellent and better quality than ASI, but they do not make one for the stock 165. Hope that clears things up for you.

Which Koyo unit is everone talking about? I'm assuming one of the Celica units is cross compatible with other generations....???

Mafix

well then.
stock st162 single 5/8" core
stock st165 dual 5/8" core for 1.25"
asi 52mm (i thought it was dual core)
koyo 3" st205 rad (the one i have in mine) dual 1.25" core and a real PITA to get installed. hope you can weld.

from everything i have learned running a 162 or any single core is fine until you are not moving. then even fans don't help. so i would never recommend a single core rad for a turbo. also use either high market dual pusher fans or stock fans. no cheaping out on those either.

oh to add to ricks post
the asi rad is amazing and priced great. i wish they exsisted when i made my car. the only other options that fit are pwr (not made anymore) and the rad alwayzsidewayz is running. i've never seen either in the states.
the last option is 935motorsports. rob sells a stock 165 rad at a reasonable price. the wait isn't bad if he has it in stock either. robs rads are plastic end tank. the stock 165 rad is a fiberglass end tank.

The ASI rad for the 165 is 42mm dual core; the 185 rad is 52mm dual core. You can get them for USD$200 shipped; can't beat it.

Koyo does not make a rad for the 162/165. They make an aluminum one for the ST205 and Gen6 Celicas and it's certainly not a drop-in fit for the 162/165. Like Mafix said, you'll need to make modifications.

I can deal with moding a rad, but if it is more trouble than it is worth I'd rather not. Thanks Rick

To revive this:

Which of these radiators have oil cooler hookups? It'd be nice to chill my oil on one of these as I know the automatic versions have hookups for the transmission, so running a tapped line off the oil pan would be a breeze.

none. these are all made for std transmissions.

its sad that my beater has a 2 row rad and my truck stock has a 2 row and the 22rte rad stock is a 3 row but my 3rd gen has a single row, and im going to havta buy a 2 or 3 row core and then have tanks welded on to it, because i cant use the truck type radatiators
