Looking for suggestions on where to connect to power for my new engine oil cooler fan. Manufacturer spec suggests a 25 amp fuse on the line from fan to power source.

Thanks,
Mac

An engine oil cooler fan? Holy smokes, what do you need that for? An oil cooler thermostat I can understand.

Because it gets a bit hotter in the upper Rio Grande Valley in the dead of summer than it does in BC in your worst greenhouse effect summer, especially in stop and go rush hour traffic.

Now thats a good answer. Did you know the real early shelby cobras (AC copies) had a rear differential cooler? Is the fan a pusher or puller? Ideally you want a puller so the cooler itself is a unrestricted as possible to the rushing outside air. If front grill space is hard to find you can go to the JY and get a couple of the plastic pieces that are used to duct some air from the front to the air cleaner. Ford makes some for the F150 and others that is about 4" long but only about 1.5" high that spreads out to about a 3" round ountlet for the hose. One or two of those will direct some cool air at a cooler placed in the engine compartmenbt somewhere. Gives some protection to the cooler, and maybe lets you place it and your fan in a lot more places. Fan wont pull anything through a duct hose though. How big a regular rad do you have to run down there? Tried anything other than stock for your regular cooling?

I see you got a picture of JB on your posts. I was sitting at a counter on a high stool in a bar / mexican restraunt sort of place in a spot on Young (?) Street in Toronto Canada (where the girl I was dating worked as a bartender, her brother was manager) one afternoon getting free drinks cause I was a poor but attractive drummer. This chick dressed all in white with a big panama type hat comes wildly running from the back end of the bar and ends up running right into me, wiping us both out and leaving us lying on the tile on the floor. She scrambles to her feet saying "sorry, sorry, sorry...." and runs out of the bar. My girlfriend at the time looks at me and asks "do you know who that was? ...Thats was Cathy Smith, the chick charged with killing John Bullushi" This was not too long after JB died. Just thought I'd share that. Sort of my brush with death.

The fan can be set up to push or pull but I want a puller cause that is more efficient, and I have plenty of room.

The cooler is mounted in front of the radiator in a secure location.

I am just looking for a good place to route the power wires so that I can keep everything squared away.

Radiator is standard radiator

Cool story about Cathy Smith!

I would do it as explained here. http://www.madelectrical.com/catalog/rly-1.shtml
(scroll down a bit)
Basically, come off of the battery with a fusable link, to a relay(s).

I've never done any wiring work, I guess it is time to learn.

I will read the link. Thanks.

I would run the power back to the starter relay or maybe install a junction block on the core support. Is it thermostat controlled or are you using a toggle switch to operate it manually? Either way you may want to think about using a relay to take the strain off your switches.

No thermostat, just a toggle is the plan.

I would go with Mr Thaxton's suggestion then. Use a relay. There is a how to on headlight relays in the how to section (which is always a good place to put a how to). It hooks up the same way.

Thanks for the advice everyone.

Howdy,
Will the kit instructions walk me through setting up the relay and fan with a toggle switch instead of a temp sensor?

I don't want to burn anything up with my ignorance of wiring problems so the kit sounds like the way to go for a beginner like me at least the first time around.

for those wanting to do the same on the cheap, some of the more modern german cars have differential coolers with a pump to move the oil to the cooler, etc. and those parts could be used to make the same kind of oil cooler.
check out your local junkyard....

I don't know for sure. I've ordered those relays but they haven't showed up yet, when they do, I'll let you know.

I would imagine your instructions would show you how to do that. The hookups will be the same whether you use the sensor or the toggle switch. I was reading thru the how-tos, GunPilot shows how to wire a radiator fan with a relay and temp sensor and TaZmaniaK shows how to wire relays into your headlights (the headlight switch is just a fancy version of a toggle switch). Both are well written and easy to follow. Your fan would hook up exactly the same way.

I read both of them and while they are clear I just want to make sure. My RC electrical system is flawless right now and I don't want to create a wiring project if you know what I mean.

Deffintly run it throu a relay and switch the relay on with a ingnition switched wire.There are relay instructions in thr electrical FAQ board

Just wanted to let you know I talked with Mark Hamilton at MAD today and he is a really helpful guy. He knows his stuff real well and I got a lot of info from him. Thanks for the link to his site.
