I need a new radiator, so I was wondering if there is anything I could upgrade to that would bolt in? Would a second or third gen radiator fit? My car's been running kinda hot (Half way up on the temp gauge, not during spirited driving), and the bottom 1/4 of the radiator is kinda messed up, so I'm guessing it has to do with that. Thanks.

I THINK that some first gen rads came wide enough from the factory to have a rad shop fit an extra row in, making it a 3 row cored rad. Someone else will need to comfirm years and such but I do believe it is possible.

Nothing that will directly bolt in unless you wanna spend way too much money (~$600) for an aluminum radiator, or have one custom made. Also, the second gen radiators wont fit (probably 3rd gens also) without modifications to your car (like custom brackets and junk).

just get a NEW replacement if you're running stock..wasn't there a thread couple months back for radiators.com... I think it was ~$120. I got mine at a local auto place.. got new hoses.. thermostat.. and flush the old junk out and you're set for a few years!! btw my temp guage NEVER covers the lil thermometer icon on the guage. (like a 6:30 position)

I bought a radiator from Radiators.com. It was for my wifes car, but it works as advertised, installed easy enough, and the price was very competative. I'd buy from them again.

****...here for the equivalent of about US$300-400 you can get a fully custom alloy radiator 65mm thick whatever, with polished tanks.

Ill second that. I got one for my 83 GSL and it fit perfect, and as you said, it was priced right also.

Another vote for radiators.com. The first one i bought came from 911radiators.com. DONT BUY FROM THEM. the packaging was terrible. When i called to complain the kid on the phone told me that i could send it back but ide have to pay for shipping there. so i said screw it and just kept it. Then that raditor got destroyed in a accident. Anyway, i bought another one from radiators.com. the packaging was MUCH better, and it cost less. The car runs super cool now. so yeah... just buy a stock 3-row (79-82) one from them.

I just bought one last month. The best price I could find was at www.radiatorexpress.com . $119 shipped and I had it in three days.

so no company makes an aluminum one for the 79 or does any other year car fit?

When you get your new radiator, run a 50/50 mix with distiled water and antifreeze. the distiled water will not cause build up of mineral deposites on your rad or engine, and is suposed to run a few degrees cooler the tap water due to the lack of minerals. The build up is nothing compared to before, and I have used it for 3 years now. And radiator.com seam as goos as anyone else, I bought mine from gate way for 125.00 and have a life time warrenty.

I have the 2nd gen rad in my car and except for 2 very simple brackets it fits perfect. looks cool, and works awsome.

The stock rad should be fine, but you may want to contact RacingBeat.com . Years ago they stocked a 4 core radiator that bolted into an FB. If I remeber correctly, RB had mentioned that a run of Corvette rad's fitted into first gen's as well (all 4 core and the new replacements are alluminum). However, this rad was only really necessary for a heavily modified rotary motors for racing.

I have a 3 core from MazdaTrix in my AutoX car. Cost $200 if I remember correctly.

1 more vote for radiators.com if you end up going stock.

they were fast on shiping and quite a bit cheaper than
anyone else.

Mr. ImportGuy

The stock radiator works great for these cars. There are 3 and 4 core ones out there and they work great too. Make sure you have a good oil cooler I see your car is an 83', little heatsink type oil cooler right? If you havn't gone to an air/oil cooler yet. That is a more important thing than a big radiator. Most the SCCA guys run a stock rad. with the air/oil cooler and it works great.
