Sleeper!!!!

You guys have no clue how eager I am to install those fans tomorrow. I mean, I really like my junkyard special fan... (came off a truck) but this combo should give me peace of mind for good.

The secondary fan I had was a becool something or other. I always felt it was a dodgy product and never like it much. It seemed to "move" air when the junkyard special "blasted" air.
 
And uuuuuh, incidentally it was the intern that set fire to my car last time. The poor fellow really won't forgive himself.

So who was in charge.......you or the intern? :D

Good idea to put the connectors inside some protection from the elements. Where will this be placed when it's in the car?

yes a very good idea especially if its mounted away from exhaust heat , in a dry easily accessed area, and away from any real chance of being exposed to water or mud

Black boxes call less tech inspector attention than relays and stray wiring.

Sick in bed here. You know yer a gearhead when yer posting on a forum with yer iPhone and contemplating how to wire the sensors.
 
Those fans are going to be a hudge improvment from what you where using before :eek:
 
A night from hell. I had colds before... But this was the mother of all colds.

Ran a few tests manually. Letting it get up to 200 then letting one fan, the other, then both bring it back down. The two fans together bring down temp fast!

MAN those fans move a lot of air... Perhaps as much as my favorite truck fan... and that was a pusher!

Just need to hook up the dual sensors and idiot lights...
 
The box will be mounted somewhere inside the fender. Not sure yet exactly how...
 
What is the idiot lights? is this related to the fans(light up when fans are on?)?
Thats an interesting feature. I really like light .. too much. i retain myself from installing ANY light on my car, because i know myself, if i setup one led for something there will be hundreds of leds for everything once am done :/.
Me and good old nostalgia for the vintage stuff, i like electrical stuff too much :)
 
I have 4 idiot lights mounted on a bracket under the cowl of the hood.

The lights indicate: water/meth progressively on, Fan 1 on, Fan 2 on, and line lock. I probably will add another light for 220 F alert.

I drove to work today - carnival vacation, so little traffic and not the scary stop and go that I am used to.

Still it was a forty minute drive with most of it cruising. Outside temp 40F. Bessy had the time to hit operating temp.

First thing I noticed was that cruising temp went down from 160 to 150 or lower. Presumably because the pusher truck fan was no longer obstructing airflow on the freeway.

Idling in fron of office - either fan will slowly bring temp down to 170 or lower. Both fans on quickly takes it down to 150 or lower!!!!

Ther thermostat is a 160.

The only thing I am uncomforable with is the dual sensor - 180 and 190. One can push into the rad or screw in a coolant port. For the moment I have one set up in the radiator. The other I have not yet hooked up. Gotta figure out where to place it and pull the plugs - might be tough!!!

I haven't intalled either sensor yet - still fighting off the cold. So all this was done manually.

Anything wrong with having both fans triggered by a single 180 temp sensor?

youll get both better lubrication , less engine wear and more power in most cases if you install a 180F t-stat and have the fans come on at 180-190F, oil temp must reach 215F for several minutes to burn off trapped moisture in the oil, that forms acids if left in the oil.
coolant temps tend to run about 15F lower than oil temps once the engines up to operational temps.
remember the t-stats only function is to restrict coolant flow untill the engine reaches its designed temp range , once that happens its intended to stay open until the engine coolant temps drop below the designed range, you can minimize any tendency to have excessive cycling by drilling 4-6 3/16" holes in the t-stat flange, this allows a minimal coolant flow at all times

It might make the fans cycle on and off constantly, in stead of running for several minutes.

You could also use one of these to get an another port for the temperature sensor.

I agree with grumpy
But hes driving at 40°F now.(yes he should get a 180° thermostat to drive at those temp ideally, but idont think he going to drive at this temp really often lol.)
With my 160° thermostat at summer temp it hold around 190°F(water temp)
My fan open when the thermostat open(thats about 170-190°F for me) BUT i am single fan, not duals...

Nice water hose adapter, i think it could work for tapping the heater return between the W/pump and radiator(i had to weld one 1 years ago because i couldnt find something similar).
 
Yea - I have drilled my thermostat... actually following your advice from years ago grumpy. The only reason there's a 160 on there right now is I've been a bit paranoid on the overheating side. I'll change that.

But what about a single temp sensor triggering BOTH fans always rather than just one? It makes them cycle on and off instead of running for a few minutes????

I like the hose adapter idea.
 
if it was my car ID have the fans on two different sensors so one came on at 180f- 185f and one at 195-200f that way your far less likely to have both fans fail at the same time on some long trip in the middle of no-ware preventing your car driving
