I have a 88 GTU that has a crack in the plastic radiator cap assembly (it connects to the radiator with two bolts). I found a good deal on a new all metal radiator but it's supposed to be for an automatic. Will it work OK?

Thanks

 

yeah that will be just fine.

 

Yea either model will function the sale. The automatics have a cooling coil that resides in the lower endtank, it will just sit dormant in the manual car, no worries.

Yes, it will work fine. The difference is that aftermarket radiators, unless they are 'racing' versions are usually made to fit both manual and automatics. the main difference is that there is a cooling loop added to cool the automatic transmission. This is simply not hooked up and used if you have a manual transmission.

I have one of these 'automatic' all metal radiators in my 90 Vert. It works fine in Dallas heat with or with out A/C, in stop and go traffic or at highway speeds. I have the engine driven fan and shroud, the underbelly pan on the car and I have a Mazda oem thermostat.

BTW, on some cars, the radiator is oversized to handle the transmission heat, so when the aftermarket company sizes the unit, you actually get an upgrade on the radiator. It was this way on my wife's 92 Celica Vert. The oem plastic tank rad split. The all metal automatic version was a half inch thicker core and was a two row setup compared to the single row core on the manual. I researched this and found that Toyota used the thicker radiator to handle the tranny heat. Aftermarket just made the auto unit. It may be the same thing on the rx7 radiator.

Good luck!

 

my 89 gxl manual has an auto radiator and it runs fine
