And the saga continues;

The engine miss was easy, I had bent a wire loom down allowing a ignition wire to hit the headers, burned up a wire. New set of wires, everything is good.

Except, just when I thought it was safe to drive in hot weather, FAN SHARKS!

I know this is getting old, and for me too. Turns out my first instincts about the new radiator fans were correct, resetting the controller’s temperatures only postponed the inevitable, in under 70* weather the fans cool the motor (yes, I said fans, meaning both), however in warmer weather it just ain’t happening. At moderate 75° + weather they do not cool, come to a stop or slow speeds the motor climbs to as high as 230° before I shut it down. In an attempt to make these fans more efficient, I fashioned rings to fit around the fans by cutting the bottoms out of 13” deep dish pizza pans hoping to increase their static pressure. While it did help a little, it is still not enough to cool the motor at a stop and low speeds even in moderate temperatures (I can only envision what hot weather will bring).

Back to tech support, they can not understand why their fans are not cooling my motor.

Just to confirm my suspicions; I remove the latest fans and re-install the original fans, the ones before the high outputs (previous to the last). Just to give you a little background, the original fans are rated at 1700cfm each, the previous high output fans are rated at 2200cfm each and these latest and greatest fans are rated at 3300cfm each. The original fans (1700cfm) cool the motor, and, they cool the motor running on just one fan most of the time. This confirms my suspicions that the latest fans are not up to their claims.

Giving up with the manufacture and their support.

I contact the supplier I purchased the fans from, their customer support representative tells me they can not take the fans back once they have been installed. I explain that the fans are not living up to their claims and ask to talk to a supervisor. I explain to the supervisor all events and he puts me through to their tech support, tech support reviews everything and agrees with me the fans are not doing what they claim. Tech support sends me back to customer support and they agree to take the fans back. Perfect, and the reason I buy through this supplier!

About now, some of you are thinking why did I change the fans in the first place? And, that’s a good question; while they did cool the motor most of the time, they did not cool it very well with the A/C on, and occasionally in hot weather the motor would run warmer than I liked in traffic, even with the A/C off.

Lesson learned, cfm ratings must align with current draw. And I knew this, just got caught up in the claims of a more efficient motor. So, I boxed up the latest and greatest fans and sent them back. Ordered the pervious high output fans that actually live up to their claims. However, the fans are out of stock on backorder, and not expected for 30 days or more.

I guess I’ll be using the original fans for awhile, along with old style A/C, windows down and fast. LOL.
