Never in life have I seen anyone put so much automobile knowledge in such short videos. You are the greatest!!? Thanks Scotty.

[scottykilmer]

hey, that's how I get paid. You think I'm doing all this work for absolutely nothing? Do you work for free? Long live the commercials if you want my free advice.

This tutorial has literally saved me. Stranded at night at a place far from home. I just temporarily fixed it myself. Much thanks for this.

That was the best (simplest) explanation I've ever seen on troubleshooting a powered circuit.

Most people's explanation starts at the front of the circuit and works out. This one starts at the back of the circuit and works forward.

I love your video.. to the Point! and I love that you gave more than one possible reason and solution. Thanks.

[scottykilmer]

depends on the car, but if you have a car with regular ignition switch that uses 12 Volts and not a computer driven one, you can wire the fan off power on the ignition switch, put a relay in line with fuse, and send the power wire from the relay directly to fan positive wire.

[scottykilmer]

you just get the one wire on the connector once plugged off the switch and connect it to any metal part of the engine to ground it. Fan should come on then

[scottykilmer]

they are made to come on when the coolant gets to a certain temperature, OR when the AC is turned on. They cycle on and off when normal

[michaelcarrillo]

Quick, fast, specific and to the point. Great info, love how he pops out of the trunk!

I have watched so many mechanical videos on YouTube and this guy here is the most simplest to follow 👍

[scottykilmer]

have the battery and alternator load tested first, places like auto zone do it free. Often a weak alternator does that, but if not, fan motors are probably worn and using too much power and need replacing

[scottykilmer]

they do cycle by computer and sensor operation, often they have a time lag. As long as car doesn't overheat and the fans shut off when the car is turned off, leave it alone

[scottykilmer]

if it doesn't overheat, live with it. Often a bad computer circuit does that and they cost a tonl You could guess with a new temp sending unit for the fans though if you want an educated guess

Hey Scotty, thanks for the great DIY vids. As a novice, I've been working on my own cars for 42+ years. Right now I'm trying to resolve an intermittent hard shift condition in my 2000 Chevy Impala 3.4; the old girl has close to 218, 500 mi on her. I've been researching the issue, and subsequently replaced the transmission filter (fluid was changed only a few months ago [2, 000 mi)), Replaced the coolant temperature sensor, and the radiator cap. Radiator, and cooling fans are o.k. I bled the cooling system (it's not using any significant amount of coolant), and cleaned the MAF sensor real good. The engine runs like new; I take care of my stuff; you know, regular oil changes, adding fuel injection/combustion chamber cleaner to the fuel regularly ("Chemtool B-12"), clean air filter etc. But the problem with the hard shifts persists; she goes into the hard shift mode at operating temperatures Monday I plan on taking the old girl into a local transmission shop for a diagnosis. At this point, my guess is either a bad PCS, or bad 1, 2-3-4 shift solenoid. Any guesses from a pro like yourself?

Scotty thanks for being so informative and making things easy to understand. I can tell you really enjoy mechanics and that makes it a pleasure to watch how happy you seem to be sharing your knowledge. People like you are 1 in a million. Many thanks!

[scottykilmer]

change the thermostat every couple of years and the coolant and watch the temp gauge closely so it doesn't

[outlaw]

Your videos have helped me BIG time with my cars, I love that you get straight to the point. Your personality makes it a good watch too. Thanx

[wlodown]

Scotty you are the MAN!!!! Again you helped me get my Daughters Corolla running like new! Couldn't do it without you.
