if you are going to the trouble to do automotive electrical and doing an electric fan install, use non isulated connectors, solder all connections use shrink tubing to seal all connections , use split loom or similar product to protect your harness , safely route and secure harness if you are running your wiring to test system, do not waste time or connectors, use marrets to test only, then solder / seal all connections
I have a 03 focus that I have replaced every imaginable part on! From timing belt & tensioner, serpentine belt & tensioner, 3 alternator's, coolant head temperature sensor, cooling fan solenoid, cooling fan relay's & tested the fuses! I lent the car to my girl & she brought it back knocking after a few weeks. I rebuilt the lower end & several other parts, timing, water pump, belts, tensioner's & replaced the exhaust, wheel bearings & hubs, entire front suspension, upgraded the brakes to vented & slotted rotors, new ball joints & then I added a 2 din 4G smart radio w/gps & camera, got two subwoofers & amp, 1 farrod capasitor, new seat covers, pulled the seats out & swept it out & scrubbed the carpets, swept again, as you see, I take care of our car's but, then I noticed why I had to rebuild the motor was because my cooling fans were not working! I replaced all of its parts! the head temp sensor, cooling fan solenoid, even swapped the relays, ran my own power & ground to the fans to ensure the do work & YES, THEY WORK, AT LEAST WITH A 15 AMP FUSE, THEY CAME ON & THEN, WIRED UP TO FACTORY WIRING, I DISCONNECTED MY HEAD TEMP SENSOR & THE FANS RUN CONSTANTLY, FRYING MY ALTERNATOR AFTER A FEW WEEKS, SO, I AM CONSIDERING GETTING A HAYDEN 3651 COOLING FAN CONTROLLER. HOPEFULLY THIS IS THE FIX? I REALLY HOPE ON HAYDEN'S MODEL 3651, THAT THE TEMP SENSOR SCREWS INTO THE FACTORY SPOT FOR MY HEAD TEMP SENSOR???? OR ELSE I AM REALLY IN TROUBLE STILL!!!
just to add to my experience, just bought a 2004 5.3L 4x4 sierra and the temp gauge sits at 210 or just below it and doesn't really move from there. Soon after I replaced the water pump and thermostat with an 187F and replaced the clutch fan with an single elec. fan while keeping the stock oem 28.5in radiator and no fan shroud, other than the the elec. fan shroud. My aftermarket fan controller runs 20 degree cooler since its a radiator temp probe. so I have it set to kick on at 180F which the PCM obd2 reader reads at 200F. Now i never did check what the PCM temp was prior to the elec fan mod or new water pump/thermostat. As of right now my temp gauge stays at or just below 210 even tho the PCM reads 212F. the single elec fan is constantly running and doesnt cool it off enough to turn off when idling but as soon as I drive temps drop to 197-205F and 212F at idle. Is this good operating temperature for a single elec. fan?
I've overheated as a result of a water pump failure on my 5.3 but I've never witnessed the temp get that high. I would like to address a few things like I hope my kit comes with instructions like that. Also they do make pliers that your supposed to use for crimping those crimp connectors and last time I checked less than 10 bucks at the local auto part store. Also when the temp gets that high again it's best to check out why like maybe the sensor isn't closing circuit as it should or even none of them will meaning your probably best off just wiring to the ecm.
good video @tahoe Steve, where did u buy the sending unit or is it the temp sensor? also if the sending unit is not connected how are u able to tell the temperature in gauge on the dashboard I'm a lil confused please help
my apologies. i was so exhausted the day i did this i didn't realize how quietly i was talking. i make an effort to speak louder in my more recent vids.
Tahoe Steve The reason that you had a hard time crimping those connectors is because they are meant to be use with a heat gun. The solder melts to connect the wires
So - the 3rd relay is optional. it will allow you to have the fan(s) on (overriding the temp control switch) when the A/C is on. not sure about your specific make/model, but that is the premise of the 3rd relay. make sense?
@@TahoeSteve I kinda understand what u mean not very good with relays i have dual fans how would i go about running them on relays if i don't wanna add temperature switch cause they fail alot ive had two in the past that have failed within 7 months if i just want them to run anytime my car is running if u understand what im trying to say thanks for any helpful feedback
Steve's 5 C's I got the same setup for my 01 Yukon Denali but the sensor won’t fit. I also bought a 1/4 npt sensor n the same. Do yu know wat size it is
thanks for commenting, but i just followed the manufacture's directions. The thing never gets that hot though. Not even in 100 weather in dead stop traffic.

you can buy a really good crimper for just a couple of bucks.
Does the added wire from your relay connect to a trinary or binary switch for your a/c or directly to the power line for the a/c clutch?
What size is the other fuse in the fuse tap? 15 also?
Did the temp go to 220-240 because there was air in the cooling system?
So question when replacing my radiator with one that comes with fan do I have to keep the clutch fan or do I have to remove it
can you provide the diagram, i think it would be very useful.
What circuit did you use? All of mine I found under the hood are a constant and the fans continue running after the engine is switched off.
How many amps is your alternator my voltage drops when the fand come on to like 12 volts
Could i wire the fans the same way on the 05+ fans on my 04? Just get the pigtails for the fans?
When you buy a Griffin radiator it comes with sender an wiring harness
yes
Great video 👍👍👍👍👍👍
good video @tahoe Steve, where did u buy the sending unit or is it the temp sensor? also if the sending unit is not connected how are u able to tell the temperature in gauge on the dashboard I'm a lil confused please help
I used a sensor in the pepcock and a separate gauge as I didnt have a trans temp guage in the main cluster.
Steve Schwartz did you retain the factory mechanical fan ? and is that a 3 row fan ?
no - tossed it, it is a 2 row
Buy a freakin' crimper, they're cheap !
How much the fuse should far from relay ?
I am facing fuse and relay heating issue , maybe cuz my fuse very near to relay ?
Are you using the right gauge wire? Fans draw a lot of amps.....is your ground nice and clean?
Can barely hear you...
my apologies. i was so exhausted the day i did this i didn't realize how quietly i was talking. i make an effort to speak louder in my more recent vids.
@tahoe steve can you send me a picture of the paper of the electric fans please
I will try to dig them up.
pressure pliers/vise grips
What year Tahoe? You didn’t have to tap into the ECM or anything?
2002 and no
What did you use for the ground on the relay
Depends on how you want it wired
What is the relay part number and and where did you buy it?
Just a standard relay in the auto parts store
What relay kit did you get
just whatever was available at my local car parts store
What fuse did you use?
i'm pretty sure they are 30's.
In the fuse tap what size another 15? or just the the one fuse
No shrink wrap??
i did it later after i ensured that everything was working for about a week.
Tahoe Steve
The reason that you had a hard time crimping those connectors is because they are meant to be use with a heat gun. The solder melts to connect the wires
So did you use 2 relay kits ? And why ?
one relay for each fan, then a 3rd relay as the switch for tying in the A/C
@@TahoeSteve ok but do i need the relay to turn ac on im installing on 90 Chevy Caprice because my ac is not a electronically unit since a older car
So - the 3rd relay is optional. it will allow you to have the fan(s) on (overriding the temp control switch) when the A/C is on. not sure about your specific make/model, but that is the premise of the 3rd relay. make sense?

Where did you buy the fans??
came with the radiator
Where did u get that sending unit?
came with the radiator

man, i wish i did, but it's been so long since i did this i forgot.
195 is way too hot your risking of blowing a head gasket
thanks for commenting, but i just followed the manufacture's directions. The thing never gets that hot though. Not even in 100 weather in dead stop traffic.
Son you might have some good things to say... but we can't hear you. Speak up
Noted, thanks!
You're difficult to hear 😒
i think i was under the weather that day, sorry.
