Hey guys I have and 84 t-type with a few mods on it. Runs good and all but one thing i fear is the cars seems to get too hot to me. Has always done it since i had the car. Ive already plugged the coolant lines to the TB, have 160 thermostat in it, Griffin aluminum 2 core(large cores) radiator, 16" electric fan. Nothing special with the fan just a cheapy. Think its about 1500 cfm. The car at operating temp usually hits about 190 degrees still and sometimes even goes higher past 210. The air doesnt work so i dont know how much higher the temp would get. Just dont want the car to over heat anytime. That cant be normal. Is it? Do i need to change the radiator to a 3 core again and possibly dual electric fans? I also have a Spearco front mount intercooler on it. This is my only serious prob i have always had and thought going with an electric fan and aluminum radiator would solve my prob. Also would a 4 core radialtor for a 81 firebird trans am turbo work? Its a bit larger and not sure if it would fit. Havent done measurements yet. Would that possibly solve my prob. Any advice would be great and if i let anything out let me know. Sorry bout the long message. Thanks
I think 1500 CFM is too small. Ramchargers has a great dual fan setup for arround $90 and is 2400 CFM. Also make sure all of the "air directing" stuff is in place in front of the radiator. When you put that dual fan kit on. put some weather stripping around the edge, to make sure the air that it is scucking, is coming through the rad.
How is the fan switched on? The computer contols the low speed in the 86/87's. High speed is controlled by a temp switch on the block at 210 to 220 deg.

Well i know my fan setup doesnt have any weatherstriping around it to direct the air more through the rad. Ill have to do that. Yeah i figured that 1500 cfm would be too small. Wasnt sure. Someone told me that an aluminum rad wouldnt be as good as a a 3 core like what they came with. That true? My fan switches on with an adjustable thermostat. Works quite well. I also have a backup switch in case something happens to the adjustable thermostat. I can switch on the fan anytime. So would more air help with cooling? Or would i need to change the rad also?
Thanks
A common mistake is made by only looking at the number of cores on a radiator to estimate it's efficency. The correct way is to look at the amount of surface area, over the entire radiator and the material used (copper and brass are actually slightly better). You said it has "wide cores" so your radiator should be just fine. You never actually said, but I assumed that your problems were when you were at a stop. If that is the case, the car is simply getting enough air while moving, and not at a stop. So yes more air while you are stopped (via fans, and propper "directing" of it) will do the trick.
