·Finally installed the electric fan today. It was a Bosch from a Volvo 740 (I think). What a fan! This thing moves some air & seems to free up some noticable hp too. It is an easy, very clean install. The original radiator was also cracked so got a new radiator at the same time. Used a fan switch from a '86 Celica GT (on at 194deg off at 185deg) & is a normally closed switch (which I didn't know until testing the switch in hot water.) This is actually a great design because if the switch fails or if the switch wire breaks, the fan stays on & you know there is a problem.
To do this you must hook the 12V to the fan up to the 87a connector on the Bosch type relay. I put the switch in where the charcoal canister switch "used" to be.
Makes for a really quiet motor also when the fan isn't on, all you hear is the burbling 3" exhaust without the constant loud roaring of the motor fan.
Fan was $30 + $15 shipping (ebay), switch was $32 at AZ, had the relay, wire & connectors.
Ya'll need to do this upgrade.
