they made my radiator) was to use a puller fan as it blocks less flow, so if=
you can I would move the fan to the back if there is room. The NASCAR guys=
build their oil coolers into the radiator and that is what I did, it is in t=

it warms the oil much quicker.

Is it going out under the car or are there cutouts in the hood, possible s=
ide vents? This is something to consider, as the speed you can make likely m=
eans a ton of air going into the engine bay, it has to exit somewhere. You c=
ould have a situation where there is no air flow through the radiator at hig=
h speed.

alum radiator (50x50cm x 8cm) developed a very small leak but it would only=
happen when the thing got up to temp. It was very hard to find. You might=
also try changing caps. If it is not in the cooling system I would look at=
the ducting and airflow out from engine compartment. It could be a simple s=

didn't help either. The difference between radiator in and outlet is 10=C2=B0=
C (50F). Not enough I would say. Maybe making the pump more slower? It was r=
unning on a ratio of 0.8 slower than crank, currently 1:1 speed. Any ideas? 1=
0 Liters are circulating.

es with no change. Changing pump speed didn't help either. The difference be=
tween radiator in and outlet is 10=C2=B0C (50F). Not enough I would say. May=
be making the pump more slower? It was running on a ratio of 0.8 slower than=
crank, currently 1:1 speed. </span><span style=3D"font-size:10.0pt;font-fam=
