Jack,
An entire second radiator seems like overkill for the 1275. I've used a KIA
aluminum core radiator mounted with the top tilted toward the firewall to
give enough clearance for the bonnet. The hose connections are reasonably
close to correct, and with the oil cooler, there is no serious heat problem
with my rather 'hot' 1275 in the Davis CA summer weather (the last two weeks
have been 100 or more, aaarrrgghh!). If I push hard on the freeway when it
is over 100, the temp does start to creep up toward 210, but backing off
slightly to a reasonable 70mph and laying off the turbo brings it back to a
steady cruising temp of about 195. If you want a pic of the installation, I
can e-mail one to you. Sorry I forgot which KIA radiator, but I just walked
the line at the Pick-and-Pull with a tape measure and took the first one
that was the right height and connection location. About $20 as I recall.
