This must be the 3rd time changing this fan I my Evo7 in the past 6 years. The first time was with a used Evo9 fan (the looked the same) and the last time was a 3rd party OEM fitment from Amazon. Someone suggested that my AMS intercooler might be pressing against the fan motor causing it to fail prematurely.

The stock fan has 2 speeds. I have no idea of the CFM at each speed or if both inputs are 12 volts.

If both inputs are 12V I could probably hook both inputs up to some relays and join their outputs to power a single speed fan with a slimmer profile and higher CMF rating.

Thoughts, opinions, suggestions?

 

long idle times or stop and go traffic work electric fans prettty hard. if your doing alot of highway driving they should last awhile.

 

It's a mix but the car does about 74Km/day during the work week. There is no 2 ways about it. The Evo needs the second fan. I did end up buying a Spal 30100384 and a couple of relays but when I took the bumper down, the AMS inter-cooler was pressed so hard against the fan, that both +ve appeared to be shorted and the negative terminal was burnt out. Added a slight spacer to give an extra 1.5mm of clearance from the inter-cooler, taped up the +ve wires, and hardwired the ground. Everything is hunkee doree now. The Spal is a much slimmer profile so if this happens again, I'll drop it in.
