The radiator cap is the last thing most people look for...good advise scotty..

[andreaslopez]

Just fixed my van with the opposite problem - wouldn't get hot enough! Threw a code indicating a bad thermostat, turned out the thermo was stuck open! Replaced it without much problem and it's working great again!

Scotty, it works this way, the boiling point of water increases with pressure, about 2dF for each #1 of pressure, so a 15 psi radiator cap allows the coolant to run about 30 degrees hotter b4 it boils. Modern carz have higher temp thermostats making the engine run warmer, this is for emissions and fuel efficiency but it is probably a good thing generally since other things are better when warm. Then of course we put an AC condenser IN FRONT of the radiators so the already hot Texas summer air is even hotter, radiators work on temperature differential, i.e. the air flowing thru is cooler than the coolant, since we can't make the air cooler so instead we made the coolant hotter. This all works out OK providing you maintain pressure in your system and run a 50/59 mix of antifreeze and water (modern antifreeze has a higher boiling point than plain water) this allows the system to get above about 250dF b4 youse is in trouble.

A real engine engineer taught me this. An engine can only generate power up to its maximum ability to reject heat, Engines convert about a third of their fuel into power, the rest becomes heat and either goes out the exhaust or into the cooling system, if the cooling system can't handle the heat, you'll be on the side of the road. A lot of the muscle carz of the 60s and 70s had this problem. If you tried to run them at sustained high speeds they'd overheat. Small block V8s were especially prone since in making them smaller they left way less room for the coolant passages, couple this with a small radiator and youse is in trouble. Fords of that era had less problems since Fords generally had about a 1/3 more coolant capacity than the competition. This is also true of oil capacity, super engines not only oil bearings at pressure but they squirt oil on the bottom of the pistons to keep them cool and they use an oil cooler as well as a radiator. In case youse was wondering why your car engine is rated higher than the same sized truck engine, the truck engine is rated at 'continuious duty hp while your car is rated at instantanious peak hp.

Love your videos scotty. I like how you keep it real not like most mechanics

[tangoandcars]

Scotty seems like a chill mechanic while working on cars unlike most of us that use every word of the swearing dictionary just to get a part on.

[wayneo]

When I was a kid I had a car that started to overheat. Me and my friends were pretty knowledgeable about cars but this had us stumped. I took it to a station and he found it was a collapsed baffle in the muffler that was blocking the exhaust flow. He replaced it and it was fine. I was impressed.

[jimmysmith]

Replaced thermostat water pump etc ended up being $13.00 radiator cap haha! But Scotty explained it well on what was going on!

Hi Scotty, I have been a car-guy since the age of three. Yes, I could accurately identify nearly everything under the hood. Fast-forward to my adult life I became a wheeler-dealer, then later-on an award winning Automotive Service Advisor/ Assistant Manager in charge of a garage full of ASE Certified talent. I have no ASE Certification. I was certified by Maremont for Exhaust, and held other certifications in tires and brakes including emissions. So, I know my way around cars and the business, better than most. I have to tell you Scotty I have not found one exception to anything you have ever stated in your postings. You are amazing and make me very happy knowing there is hope for customers needing service. I live in the land of crooks in the Fox Valley Area here in Wisconsin. Now that I am retired due to illness, from time to time I visit auto shops for this that and the other. Most people don't know me so I never let on that I know anything. Too many times I have been horrified, shocked and disappointed at the laziness when it comes to car repair where I live. Nobody wants to take the time to properly diagnose, they are all a bunch of "parts-replacers." That is just about the bottom of the barrel when it comes to quality work. There are several large chain stores who are among the worst offenders. But the shoddy shops sure know how to find unnecessary repairs and charge up the butt for it at ridiculous prices. I wonder at times if these people go to church
on Sunday or what they teach their kids??? There is enough business out there where auto repairs can be done efficiently and without over-charging. Apparently these guys skipped the training on repeat business and earning the customer's trust. I have a 3 year old Chrysler Van with a full Warranty. The dealer wants $90.00 or more dollars each time I bring in a situation covered under warranty- before they have done anything!!! For what?! To bring my Chrysler into the shop and write up a work order?! Shocking! The first time I knew I made a mistake taking my vehicle to the dealer was when they were going to charge me over $3, 000.00 to fix a simple small door ding! Mr. B.S. who was talking this deal over with my fiancee hadn't noticed me sitting in the passenger seat, and man did I get an earful!!! He explained the door-ding-repair in great detail saying thing like: The door is going to have to come off. The inner panel will need disassembly, that will have take up to half a day. Painting will take several days because the door and maybe the side will have to be painted as well. Now this all is for a door-ding the size of a dime. The B.S. went on and on. Then they wanted the car for over a week and were more than willing to rent me another car. I had the Chrysler repaired at a local body shop for $300.00, the car was in and out in three days and they hand washed it and vacuumed the inside and did the windows too shortly before pick-up. You couldn't tell there was ever a door ding and it looked beautiful. There is one place which has earned my trust, and I live in a big metropolitan area. I live in the land of crooks, the Fox Valley Area here in Wisconsin. Where the car repair places are more interested in your wallet, and how quickly and for how much they can empty it out for. It's like hit and run car repair! Thanks Scotty, for being one of the god guys who has a heart as well as a brain, a rare combination these days.

[mitchellt]

[ChrisxHere]

This guy has literally helped me with every single problem wrong with my car made me want to become a mechanic

[yupsir]

Radiator cap, always overlooked maintenance.

[neweraccount]

I recently got saved and can’t believe I didn’t just listen years ago.
It feels so amazing

[thespanishbull]

My respects for this gentleman I wish all mechanics be like him funny and honest.

[zulmr]

I want to be a good mechanic like you scotty. Thanks for the tips.

[WINCHESTER]

FYI back in the day I had a 79 Ford 4x4 f150 that would overheat on the highway. Took it to a backyard mechanic in SC & he backflushed the radiator & that cured it.

[RobertWilliams-hztc]

Thanks Scotty, I have not had to look up your videos for current car problems but I watch periodically to chip away at my ignorance of cars.

[bebaderci]

Gonna get me a new radiator cap. No signs of trouble yet. Why wait? My 2012 Jeep isn't gonna get the chance to give me a Temperature Tantrum.
Thank you Scotty. You're The BEST!

[georgethomas]

Of all the tools I ever had. A pressure tester was not one of them. Will be adding this to my toolbox.
