I found a aluminium radiator for a manual 73 radiator but my car is a 77 auto will it fit?


thanks

It will fit but usually radiators for manual trannies do not have the built in tranny cooler so you would have to run an external cooler.

Edit: I need to add a disclaimer... I don't know for sure it will fit. The cooler thing I know though...

 

Pretty sure they are both 27 1/2" wide cores, but I agree with Zwede that you won't get a cooler for the trans with a stick radiator.

 

Call Tom Dewitt.

 

Corvettes were not equipped with aluminum radiators in 73...they all used the same unit which could be interchanged with auto or manual transmission. The GM# 3030199 got the call to serve both big block and small block from 1973-76 for LS4, L48 and L82 applications.

PS...these were brass copper units. The unit you found should have a metal tag on the passenger side with broadcast code, date code and part number...is it still present?

 

The answer is NO. The 73 original, as pointed out was C/B, and it has a 27.5" core. The upper neck is 1.5" and curved 45 degree. The lower neck is 1.75"

The 77-82 radiator uses a 26.25" core, so it won't fit the core support. The upper neck is a 1.5" or 1.25" (depending on HP option) straight connection. The lower is a 1.5" connection.

Two totally different models, not to mention the missing trans cooler.

 

Get one of his aluminum rads. You won't be disappointed.

 

I got one and I wasn't...
