For those of you who may want to replace your own water pump - Be SURE to do something to make sure the bolts go back in the same holes they came out of .. they might use 2 or 3 (sometimes more) bolts of the same size, but different lengths. Inserting a bolt that is just 1/4 inch longer into a hole that is too short can do major damage

I love your channel. I've become so good at self maintaining my vehicles because of you. People say stuff like this takes away from mechanics but mechanics weren't getting my business anyway cause I simply can't afford to go in. So it was just driving with dangerously broken crap till it simply couldn't go anymore or try to fix myself. And I was doing alright on my own but your channel has helped SO MUCH. I can now drive my car with confidence that I'm not gonna break down in the middle of no where and I've watched enough of these to where I've built a useable on the side of the road kit in my trunk IN CASE I DO BREAK DOWN IN THE MIDDLE OF NOWHERE I can jump out and at least make the car limp to somewhere safe worthy! Thank youuuu!!! Your the dad I never had but always wanted!!

[@adrianbarraza5929]

Thank you, Scotty! I was worried it was the engine until I ran it without the belt... noise went away! Narrowed it to the alternator. Swapped it and boom, everything is back to normal.

[@terrellashley981]

Was the noise like chattering teeth?

[@spelunkerd]

For those watching, don't forget to burp air after replacing the pump. Although that step may be boring and obvious to those who know, the audience includes people who have never done this before. An overheat after failure to burp air can be a critical error of inexperience.

[@mannys9130]

Excellent addition and 100% true.

[@ComPrt3]

spelunkerd On my water pump, I had to torque the bolts on as well.

[@davesstuff1599]

spelunkerd The thermostat has a check valve built in, not necessary.

[@mannys9130]

+David's Favorite Videos My thermostat is mounted down low. Some cars, especially FWD V engines, absolutely need burping to get the air out. That's why there are bleed valves. The air gets stuck in pockets. You have to burp it.

[@thisperson6655]

How do you burp it?

[@chiquicat1]

Amazing that you took the time to make the video with a missing tooth, most people would just wait until visiting the dentist! Amazing Scotty, you have true passion and commitment!! Nice fix, rattle GONE.

[@Buc_Stops_Here]

I had hoped to learn how to find a rattle on the interior of a car, but this is an excellent explanation on how to determine rattles on the engine. Fortunately, on both GM and Japanese imports this rarely happens (with the engine) as usually the water pump fails before any rattling occurs (then again, most Japanese brands require you to replace your water pump at 105,000 miles or seven years.

Playing hockey at 63+ is pretty darn good. I use to play roller hockey, and follow the islanders win 4 straight stanley cups. Nice video. I once had to have something similar changed, as I was driving back from nyc to brooklyn and prayed I would make it. It was a pulley too. It was on my 88' olds ciera back in like 2002 or so. Someone in the city thought maybe I was low on some fluid or so but not the case. Finding noises or leaks of any kind can sometimes be hard. Scotty if you could do a video on finding water leaks that would be perfect. I'll share my story then.

great video. very informative. I'm starting to think that no matter how new a combustion engine is, eventually you have to replace or fix the bloody parts. I'm considering going electric, less moving parts they say.

If your lucky that is about all you get on a Mercedes before you have to put it in the shop every 2 or 3 months for this and that! LoL At 261k on my Camry it's still not visiting the shop for anything other then oil changes and tires...

[@shawns.2851]

Gringo Louco I'd take one if it was given to me. I guess I'd have to throw it away when it broke down. Hell, I can't afford something like that. I don't see why they sell. I suppose if you had a "disposable income", it might be just the thing for someone.

Hi thank you so much for your help I am new at this so this is first time watching this.i have a 2004 honda odyssey and it has been making a rattling sound near or in the motor sounds like .so I watched this to see how to fix it .may I ask how to burp the water pump before or after you put it on? And if it is not the belt or the pillows making the sound ,how do I know what is making the sound?

[@cristianroy21]

You got all the answers my man

[@SultanAli-lm2ge]

He’s funny 😂😂 great channel Scotty

[@sienile]

This works in most cases, but I worked on an ambulance with a roaring diesel vacuum pump and ,without a load on it, it sounded just like a new one. I had to use a mechanic's stethoscope right behind the pulley with it running to pinpoint the noise. A screwdriver didn't amplify the noise enough to overpower the chattering of the diesel engine. Good advice, but not a guaranteed solution. And it also won't work on noisy belt tensioners as they vibrate enough to make a chattering noise through the screwdriver or stethoscope regardless of if they are good or not. But for 95+% of cases, this will work fine.
