Hi i'm after some info for adding thermo fans to a eb falcon 4 litre. i have been told by 2 mechanics not to bother but i can't remember why. i'm sure people have added thermo fans to their 4 litre donks, so has anyone had any adverse effects with them, or has anyone got any advise for me. i can only see the good in them, less drag on the motor. I'd appreciate the advise.

Here's some advice; go to a different mechanic.

Thermos are one of the best mods you can do. So many benefits and they don't cost much to set up.

Waste of money. Unless you can get a proper way for the fans two kick in it's a waste. On the other hand, If you wan't a set for cheap, let me know :) . I've got an EA and I bought a set of EF twin thermos for about a year. I used a Davies Craig thermo switch. When the fans turned on, the current drain on the battery is that bad that the car nearly stalled sometimes. As far as performance gains, what performance gains. The temp guage was always going up, down, up, down as the fans turned on and off. The standard fan keeps the car cooler and regulate the temp better. In EF's, the fans are computer controlled, and are multi-speed, so you don't get current drains and the temp is regulated almost perfectly. It's up to you though, If you want let me know.

I havent had any probs with them at all...

Both of mine turn on at the same time, and also cycle with the air-con.

The car is always running cool.

Rollin has 2 temp switches, one comes on and if it gets a little hotter the other turns on. I will be getting his switches soon.

You may need to put in a cooler thermostat, as you dont want the fans to turn on to cool, and the thermostat to be closed still.

Performance gains, well at least you dont get the aeroplane sound effects anymore!!!

I got 0.6sec of a qtr time, but i put an XR cam in and thermos... I think the fact that it doesnt have to spin the fan may have helped!!!

Maybe I had troubles caus' I have an EA, apparently they are prone to overheating. I stopped having cooling problems with mine when I put in an aftermarket thermostat and a new radiator (went though two thermostats from ford and they both let the temp hover obove half way). I had 2 relays and heavy wire running to and from the fans. When I first wired them up, I had thinner wiring and I blew the fuses I installed. Not reallising (just came off a freeway) I got stuck traffic. Before I knew it, the temp was up to red : . That and the current drain problems is why I pissed em' off. You can always rely on you standard fan 99.9% of the time (the .1% is for the fanbelt but the same cant be said about the thermos, well, with mt bodgy wiring anyway.
