Title: Ford V6 heat exchanger for Holden V6?
Post by: yjet on March 18, 2020, 20:12:56 PM
Guess this has been done? Will an old 3 litre Ford V6 heat exchanger cool a standard Commodore V6 (Ecotech)??

I've got one on a 220HP Chev 4.3L without any issues - only fed from a single unit takeoff too.

If you decide to go the Holden V6 route get a 3.8 Ecotec L36 from a VT

Depends which savage heat exchanger the 80mm 600mm long one is to small ok for normal boating but when you do a long high speed run it will over heat
The 80mm x 800mm one is the one I changed to due to overheating

Naah, that's not right.
The one I believe was on the Ford V6, is 80mm dia, 400mm long core, 470mm long overall.  This is the same one I've had on my 220HP Chev 4.3L for the last decade without any issues - including towing other boats.  If yours is overheating, I'd suggest looking at size of the pipes and fittings between the jet and where it dumps overboard - as long as you have good raw-water flow it will be fine.
