2.8 v6 to LT` radiator what to do?

Hi, I see I am supposed to use a v8 rad, but that lt1 is reverse cooled... so does that mean the radiator in/out are o different sides?Can i just get a rad out of a thirdgen v8? and use custom hoses?

what about my rad? its pretty puny...

what about a 4th gen camaro rad/fans... will it bolt up?


thanks so much

You can use a V-8 3rd gen radiator, the hoses are 95 camaro z28 upper and a 87-93 mustand 5.0 upper for the lower.

The 4th gen radiator will bolt up but you will need some brackets it leans forward a little.The fans will work with a 3rd gen radiator.

Re: 2.8 v6 to LT` radiator what to do?

Use whatever radiator is in there unless you just want to swap it. Reverse cooling means the cyl heads get cooled first instead of last with the standard SBC. It has no bearing on radiator usage

The main difference is the water outlets are funny on older V6's. Using a V8 or 90-92 V6 (same as a V8 rad) puts the outlets in the standard SBC locations and you can use the normal hoses associated with LTx swaps

The 3.1 V6 version, yes. But, not the 2.8 V6. It's smaller, and has the inlet/outlet on the opposite sides.
