I've finished my turbo install and to help cooling I want to have my radiator fans to always on. How can I do this?

 

Need to instal a switch inside the car that allows you to turn them on when you want. There may be other ways, but this is my suggestion...

Just so you know if you do turn your fan on full time you will most likely mess up your rings. Yea fact is that if you car's engin is too cold then it can cause to much wear on your pistion rings. And that is a bad thing. Unless you dont mind alot of oil blow bye... Oh yea just so you no too. Most of the time your electric fan will not even come on if you are driving faster then 25 mph... The air outside cools it enough. Oh i almost for got if you keep the coolent in your car too cold and the your thermistat open and releasen too cold of coolent to your engin it can cause engin shock that is also bad for your car and can also cause you to blow a head gasket... Just somthing to think about.

 

I responded to this thinking it would be more of a cooling aid between runs at the drag strip...

Maybe but if you are running at the draggs then your car is up to running temp. And that is where you want it. Not below running temp. And if you go above running temp then your fan will come on anyways. What is the point of cooling your car down more then it needs to be. Turbo or N/A...

 

Thanks for the info, I always thought the cooler you kept your motor the better. I live in Las Vegas and it gets 110 in the summers, That's what I'm worried about.

 

Dont worry about it... Your tempature sensor will tell your fan when you are getting too hot. And it will turn it on. I would not worry about it too much...

 

Sha_dow1: I think you are far overestimating the effeciency of a radiator.

Unless you can show me a technical article, or some sort of proof of what you are claiming, I will absolutely disagree.

The cooler your car runs (within reason), the better.

But to answer the original question, unfortunately, I don't know what the best way to turn your fan on would be.. I would just use a multimeter and some splicing to figure it out..but I've never had the need to figure it out on my Honda, so I dunno.

 

Keeping the fans on won't change the coolant temperature in the engine if your thermostat is functioning properly. You could cut a hole in the hood and install a radiator fan there blowing hot air out of the engine compartment.

 

Leaving your fan on all the time doesn't kill your rings that bad, does it?

 

A. The cooling fan on all the time DOES NOT kill the rings.
B. The cooling fan switch is on the back of the block.
C. If you can't say anything productive, then be QUIET!!

 

As Gasoline Fumes said earlier, leaving your fans on all the time won't cause your coolant to run undertemperature.

Start car, coolant temperature begins to rise. When coolant temperature hits something like 180F, the thermostat will begin to open, mechanically attempting to maintain 180F-ish. Coolant flows through radiator. If your car isn't going fast enough to maintain airflow through the radiator, the radiator fan(s) will come on, maintaining the 180F. You can run 10 fans in your engine compartment, but as long as the thermostat is working, the coolant temperature won't go back under 180F.
