Hi everyone,

I gotta say, this is an amazing website; I am thankful of the info that some of you share with the rest of us. To the problem, I noticed that the engine gauge on my 2000 S type V8 (none type R) was staying warm for much longer than expected.

I'd leave the car off for an hour or so and come back to it and the gauge would instantly jump up to 1/4 and to half way within a few minutes.

So with some quick investigation I could easily see that the engine fan was not working. I've kept a close eye on the gauge and it hasn't gone past half way so it doesnt seem like theres any immediate danger to the engine but I would like this taken care of.

Besides replacing the fan does anyone have any suggestion as to things I could look into (fuses etc.)

Thanks in advance

 

The fan does not operate after the engine is shut down- there's no need.

 

Hello sasgari, welcome to the forums! The temp arrow should be "at the half way point" when engine is hot. Could be a temperature sending unit going bad or possibly a corroded wire to the sending unit that is pointing the arrow 1/4 way when the engine is first started.

 

You can watch the value being reported to the car using this:

and the workshop manual ($8 ebay) gives things like thermostat opening ranges.

 

Is it an electric fan? The Lincoln LS from 2000-2002 had a hydraulic powered fan. They are known to slow down with age.
Look under the hood for two P/S reservoirs on either side of the engine.

Yes, it's electric. There's a PWM (pulse width modulated) signal from the PCM to the fan module telling how much the PCM wants the fan driven, and the fan module then drives it (via a hefty fuse, 80A as I recall).

Wow, is this not the same as the LS? Good grief.

 

Thanks JagV8 for the correct information. The LS guys have a TON of problems with the hydraulically driven engine fan. Expensive to fix and parts are hard to find. I had assumed the only reason Lincoln used it was Jaguar did too??

Er, the jag one might also be an expensive fix for all I know

 

Man you guys are a wealth of info, thanks to all. I took it to a local mechanic and he looked it over for free.

As he was explaining it, its normal for the temp to spyke half way pretty quickly and since the engine isnt getting hotter than that it isnt a concern.

We turned the AC on to check the variable speeds of the fan and it started spinning.

Thanks again

 

Sounds like it's working
Thanks for letting us know.
