Title: Both cooling fans come on at same time
Post by: grifter on 15 August 2023, 18:25:21

Just changed the rad and condensor on my elite, changed the radiator fan switches as well, and now when I let i tickover to heat up both the front fans and the backside fans kick on at the same time - about 90 on the guage then cools down to about 80 - is it not the front fan first then the other 2 at the front when it gets really hot?

Before I done this work I noticed the front fan came on but the temp just sat at 90 with the front fan running for ages and never really turning off, the 2 front fans never came on it just sat about 90 degrees.

Granted it now cools down much quicker so it's not really a issue in itself just wondering why both fans come on at the same time.

Doesn't the front single fan come always on when the air con is on? The two rear fans have a low & high speed

As you've discovered the guides, there's one for testing the fans.

Front fans only run with Aircon on or if the radiator temp exceeds a certain point. The dash gauge is irrelevant and may as well not exist.

The radiator fans are self sufficient with an override for AC sent via the engine ECU.
