I was also with a guy with a 1.9 in hos Suzuki. He has a Quantum radiator in it. Boy are those things tiny!! My current rad is much bigger, and I still had problems, but we are both close to 3500 lbs. I heard a tip to use a Ford Taurus fan from a 3.8 V6 engine as it pulls a lot of air, 4000 CFM. It is a 2 speed fan, and even on low, it seems to have greatly helped my temp. So if any of you have a taller than stock rad and overheating problems, go visit a junk yard. One word of caution however. On high, it draws 100 amps for a few seconds at startup, so it needs 10 Ga wire and either 2 smaller relays, or one probably 70 amp or so relay. It draws 12 amps on low, and 30 amps on high, but it sure puts out the air!!
what setup were you running before? what is your rad from? the rover???
i'd still say that all you need is something that draws air over all parts of the rad... such as the dual fan setup on mk3's
Aftermarket aluminum. I don't remember the size, but I think it's something like 18 x 24, and twice as thick as the Quantum one. I have had a shroud the entire time, so air has always been drawn over the whole thing.
I just stuck a 'thinner' Quantum TD rad in a gasser Quantum and it cools much better. If I could get one for an a/c TD Quantum then it would cool even more.
Looking at 'modern' cars their rads are paper thin; and I guess even more efficient.

that makes sense. less restriction = more airflow = better cooling
That's probably another reason the Taurus fan helped me. I have 2 oil coolers behind the rad, so more restriction to air flow, plus the IC in front of it, although it is spaced several inches away unlike the oil coolers. Plus it has it's own small fan.
