Heavy duty cooling fans
Does anyone know of any heavy duty cooling fans for a 91 xj? I live in a hot desert and I want to keep my baby cooler. She runs a little hot after an hour on freeway and also I can see the gauge creeping up when I'm idling. I already replaced my thermostat and the t stat housing. Anyway let me know if you guys know of any sweet cooling systems!

Spal is a company that specialise in fans. They do a range of very long life motors. A pair of 7.5" fans in front of the rad should help you out.
Don't know where you'd get them over there though.

Three months or so running their triple fan kit and I haven't been able to overheat it.

you have two fans the one on the passenger side runs on the drive belt it has a clutch it mount to then to pully if the clutch is bad the fan does not spin correctly when xj is up to operating temp the fan should be stiff to turn if its not the clutch is going/gone bad it pulls air thru radiator when idleing to keep cool, run to normal temp shut motor off and spin the fan see howtight it is

The little thermostatic switch they send you has simple instructions with it. It's adjustable, uses a sufficient relay, and is color coded. I went a different route and wired each fan independently so they come on at increment temps, but don't tell ffdynamics because it'll void my warranty (shhh).
