Well my moms 91 Honda Accord with a F22A1...needs a new radiator..

and basically I need a bit more cooling for that engine cause it has about 275,751 KM...

So I thought to myself why not use a H22 Radiator from a 92 Honda Prelude..but I have a couple of questions:

1)Is the H22 rad larger than the F-series one (My guess is yes)
2) How is the fit in this car..do I need to drill new holes or is it a straight bolt on?
3) Last question is compatability, since the car is automatic, did the H22 ever come in automatic or just straight 5-spd...if I use a 5-spd rad can I still use it despite the fact the car has an auto tranny....

Thanks everybody for you help

 

i think you need a manual ecu if you need to get your h22 run with auto.
you prolly will run into bullshit like that..
that's what i heard, im kteller8, i think he's been searching for a h22 auto ecu

 

you wont need a new ecu to run the radiator. Just go to the local parts counter and ask them for the radiator in an automatic format. I believe the newer H22 preludes had that auto-stick stuff. But now would be the best time to get an A/T cooler, an external one, which will drop AT temps down pretty low. That way, you can sticl with the M/T radiator, and when you switch over to an H22 or whatever, you can modify it to be used as an oil cooler instead. It's win/win.


but if you want better-cooling in a bolt in situation
you're better off getting a more efficient radiator. Right now, I'm running a single core radiator, but if i wanted more cooling, I'd get the double-core heavy-duty radiator.

 

radiators for autos have a core integrated with the radiator to cool transmission fluid, while radiators for 5spd do not. using a manual radiator and using an external tranny fluid cooler will NOT provide sufficient cooling of the transmission fluid because tranny fluid coolers are designed to work in conjunction with the radiator w/integrated trannyfluid core.
you will most likely roast your torque converter along with the autoclutches from excessive heat. anyway, this is my $0.02.

 

Thanks for all the quick replies...


anybody else with any answers to my questions

 

Why does it need more cooling? Just stick with stock.

 

why would you do that just get a new stock radiator or see if they have one with more orws then stock has it will help cooling ... no need for a radiator swap to a h22

oh obd1 auto ecu's can be had all day long
its the obd2 ones that are a pain

you can use acutally a 5 speed ecu and keep your auto tranny controller.. big james did this.. he acutally took a GSR ecu and had it chipped and ran his accord TCU and ran like a 14.5 without being tuned and before alot of parts

dependin on where the post are on the radiator, you may need to fabricate some new mounts for it.

If it is an Auto rad going into a manual no biggie just plug the holes for the cooler with some bolts. If it is a manual into an auto, it is a no go due to a lack oil to water cooler. Now there are some companies that actually sell the same rad for borth cars and you just leave the plugs in for the oil to water cooler.

I would be careful about adding a large air cooler as most moder automatics operate the lock up torque coverter based upon temp of the tranny fluid.
