Lots of questions about the air hammer tool. It's this one from Lisle:
Way back in the day I bought a used Chevy Chevette. After a month or two the starter quit. The mechanic got a rebuilt one and put it in, It worked for about a week. This process repeated 5 times. He told me only rebuilt starters were available. Since the rebuild shop was local he called them. The original owner had sold out about six months before and the new owner was doing what is typical, cutting costs everywhere he can, which included hiring unqualified help. Anyway, my mechanic talked the old owner into overseeing the starter rebuild and lo and behold that starter was still working fine when I sold the car a year later. Shows to go ya, there is no substitute for knowing what you're doing.
Max doesn't say much but his looks and body language make up for it. Great dog.
The electro-viscous fan clutch (yes, that's the name) basically just replaces the little bimetallic doodad that purely mechanical fan clutches have with a solenoid. Internally the clutches still work the same. Solenoid opens up, allowing the silicone fluid to enter in the "friction" area at a controlled rate.
FordTechMakulco is a good guy to watch too. He is so talented with Fords that he gets customers from all over the US, which limits the number of videos he can make. In one instance the Ford dealer wanted to replace a customer's engine when the only thing wrong was a bad electrical connector under the hood. Great work Wes. Thanks for the video.
No matter how much experience you get, your only one thought away from putting a spanner or wrench across some battery terminals. Thanks for the great content Wes, genuinely look forward to them.
That was some unfortunate timing, Wes. "Yeah, we're fixing the old girl up" just as Mrs Wes is climbing back aboard. 😄
My dad always yelled at me when I’d put tools on the battery, so I started putting part of a mud flap on them first.. so now I’m older, let just say a few times I have put tools on them, and I was reminded why not to do that. Great content as always
Had to laugh when you said ‘fix old girl up’. Thought you were in dangerous territory.
Stick shift never would've stopped my wife. She was as good with a manual as anyone. However, the vise grip parking brake release may have thrown her for a second.
Watching you set the air hammer there earlier in the video, I was thinking "i'll bet that thing doesn't have the little insulating cover on the battery terminal anymore" Always living on the wild side, Wes :D
Wife-proof. Pure gold Wes. Pure gold. 😁
Wes, you have to put more outtakes in your videos. The battery sparking was hilarious and so was the sigh of a long day in the shop. But the wife proof comment was also hilarious.
I had a pick up with a 5 speed manual when I met my wife. “I can’t drive a stick shift , you can teach me later “ she told me.. 25 years later I’m still waiting for the first lesson! Lol
Love the shorting battery shot! You keep it real!

Hi Wes. There is a simple "magazine" test for fan clutch in my country. Take a magazine(not wife's favorite 😄) roll it and put it into fan when engine's run. If the fan stop or going slow, congratulations, you win a new fan clutch. We also call it viscous clutch, there is something like liquid silicone inside. Sometimes could be repeared with new silicone, but only sometimes, and is temporary. Sorry for mistakes, i didn't practice writing for years.
I replaced the whole pulley / fan clutch system on my 5.9L pre-emptively at 225k miles. The replacement clutch quit working in a week. The original clutch is still going strong at 20 years old and 320k miles. Luckily the old 5.9s didnt need fan clutchs, it never got hot unless towing heavy, just no airplane noise.
The battery thing... been there, done that.
My favorite part is Mrs. Wes's face when he is videoing her on the mower... That expression is priceless!!!
