How to diagnose and fix engine noise

This video documents the investigation of a knocking sound on the right side of the engine bay, in a 2005 Toyota Corolla LE sedan with a 1.8L, 1ZZFE naturally aspirated engine. Various methods for coming to a clear diagnosis are discussed.
Using methods shown in the video, we came to the conclusion that the knocking sound was coming from failing bearings inside the water pump. We go on to show how we replaced the pump using an anterior access method by removing the alternator and sneaking the pump out the front, without having to remove the motor mount or gain entry through the right front wheel well. Details of how to remove alternator connections and water pump connections are shown. For better access you can support the engine and remove the motor mount to get better access to those two bolts at the back, which are done entirely by feel if you use the method shown.
Auto repair is inherently dangerous both to person and property, even more so when the operator is inexperienced with inadequate tools. Specifically if you fail to adequately burp the cooling system you can destroy your engine, so be sure to carefully do that. Never rely on any single source for critical facts. The information provided here is offered in good faith, for free, but with no guarantees as to accuracy or safety. Before stepping into any repair, you need to honestly assess your own experience, skill and tool set, and your willingness to accept risk.
Any misadventure you encounter if you decide to accept the risk of DIY repair is your responsibility.

Excellent point with installation of the longer bolts first !! Also the use of an old sock is a great idea to isolate the battery cable. Many times , I will use a rag , wrap the cable end then wrap with tape. Well done video !! Thank You !!

Thanks, Ben. An old childrens' sock would be best. My wife still gives me stink eye when she finds one of her old socks in the tool box, ha ha. The dryer doesn't eat all of them.

Great work Dave! One of the tools I use to pinpoint which accessory is at fault is to use an ultrasonic tool. Keep up the good work and have a great day! 👍

Thanks, Shawn, I agree. Diagnosis is also the skill that takes longest to mature, you need years of experience and it's hard to learn it online.

Great instructions. Looks like a knuckle basher! Those pulley types where the back of the belt provides the drive not the toothed side cause the belt to wander and the bearing to have an offset load. We had a vehicle that had this set up. I think it was Cids Ford Puma. Sail Safe mate. Ant & Cid

Grey pneumatic makes sae and metric sets of semi deep sockets. You may find them useful, and they're not prohibitively expensive. They've often been the first sockets I have reached for since purchasing them years ago.

Great job! I like taking off the belt just to see if the noise goes away. I think I would’ve replaced the thermostat since they’re only like 15 bucks and you’re already in there 😀

That's a lot of work. I remember when changing a water pump was just a matter of removing the drive belt and loosening the bolts holding it in, not all of this complicated stuff. This job may just be best left to a good mechanic. Just curious, how many miles did the Toyota have on it?
@spelunkerd
@spelunkerd Год назад
193,000 km, and almost no oil underneath, with very few codes on the scan tool (just a history code for a seat belt that didn't return). When cared for properly, these old Toyota engines are great.

@@spelunkerd Thank you for answering my question, and that's around 120K miles. We have a 2013 Corolla with only around 53K miles on it. It drives like a dream, and I'm keeping it well maintained. I could see this vehicle getting well over 200K miles if properly maintained as you said. 👍👍👍

Good point, Glen! Imagine how much better diagnostics would be if one only worked on one brand of vehicle. Strangely though, the professional general mechanics who do everything develop a depth of experience that is hard to beat. I admire the way they improvise with tools they have, often making tools to accomplish the task.

dang it i subscribed years ago but didnt put it on ALL notifications so've been missing all your dog dodge stuff . ive 94 short bed and 2000 3/4 ton dodges so i need LOTS of tips LOL . anyway great vids ! also ive a tip for you = im in suburban detroit area north end of lake st clair . and here in the macomb and oakland county area there are currently 100s of snowblowers for sale at like 75% off as it hasnt snowed seriously here in years . bring a trailer and shop facebook marketplace and craiglist and you'd haul home all kinds of lightly used machines to re-sell at 50%+ profit . but im not sure you might be way out west so too far away

I still have that old Dodge, it is working fine. We don't put a lot of miles on it because of fuel consumption, but for hauling brush or compost or yard work it is hard to beat. That's a good point about snow machines, we live on the rainy west coast. It's nice to hear from you, Roman!

I have a motorcycle. 2004 suzuki intruder 800cc. When I hold my clutch lever down and put it in first , while clutch is down, bike still moves. And changing gears, the gear shifter is really hard to change it kind gets stuck . Any idea what's wrong?
@spelunkerd
@spelunkerd Год назад
Bad adjustment of the clutch cable is a likely cause and an easy fix. Check that first. I would find a dealer repair manual for your bike, and find the adjustment points. My bike clutch cable has three (!) adjustment points, each of which can influence clutch position. Also the clutch cable itself can rust and become hard to move. You can buy a little tool to lube the clutch cable. I did a whole video on the clutch cable removal and adjustment, when I was fixing a coolant leak on my Vulcan.

If the sound happened after running with no oil, it may well be a spun crank bearing or something else much more serious. Oil pumps in cars rarely fail, even under extreme conditions.
