I put in an aluminum radiator from Wizard Cooling a couple years ago.
Duplicate of the original TR3, but much more efficient. No problems anymore
with water temps and I don't run any kind of fan. Now I just have to get the
oil temps a little cooler on those hot summer days. Put in a wider oil cooler
this winter and it stills runs a little hotter than we would like!

I had the same trouble in year 2005 when I used copper head gaskets.
At full throttle I had blow by at the gasket at cylinder #2 and #3.
I have run the engine hundreds of miles on the autobahn at cruising speed
with no evidence of blow by but on the track the radiator was emptied
within
5 laps.
I passed on to steel head gaskets and since then all trouble disappeared
and
I never had any overheating.
I use a simple copper core radiator of the size the TR4a had and that works
very fine.
Cheers
Chris

Betreff: [Fot] cooling down a tr3
fot, just returned from a frustrating week end at sebring raceway. the
racing was on a 1.7 mile course with a lot of time in 2nd/3rd gear and not
many
long straights to cool down. the car would run 7/8 laps with the temp going
up
on every lap. air temp was 90f+. when the gage was full scale (230f+) i'd
come in. with a 7# cap the water was immediately boiling when i turned the
car
off, with a 16# cap when i turned the engine off the hoses blew off. i've
got
the original size rad with a modern 5 row core. it's fairly well sealed so
the
air has to go thru the rad. the oil cooler is mounted in the grill opening
with a shroud between it and the rad. in three years of trying this,
overheating remains my top problem. is there any ultimate solution? thanks
for any
comments or advice. ken m tr3 vintage racer
