A video describing the process of removing and replacing the water pump on a 1993 G20 Chevy van with a 5.7 liter. Real simple to do just not a ton of room to work is all.
Years ago father in law had a flat nose 73 Ford Sportsmobile camper van conversion. He and his wife put 145,000 miles on it before it bit the dust and burned a couple valves. He was one of those " All don't mess with it, it will be OK" types . I had to wait for those two to leave town for the week in their Chevy to get my hands on that 73 van. After new valves and a valve job, water pump, timing chain ,rebuilt starter, alternator and carb, a new complete exhaust system was installed. Later we (my wife, his daughter), returned it to the same spot where we borrowed it. When they drove it in my drive, both had tears in their eyes. Seems like the old folks appreciated things a little more. lol.
This is the first video where eric started framing the video with the car in the background and giving a brief summary of the issue the car was having. This is the birth of his style.
Man, I had a van like this back in the day. Changing the water pump was such a challenge I decided to sell it after I finished. Where was this video when I needed it back in 1988?!? These are great vids. You're a natural-born teacher. Thanks, Doc.
Jeff Collins i believe this was thie first video i watched on yohr channel way back in 2014. Ive been watching everyone of your vids ever since. Been a sub for a long time and love all your videos.
Thank you so much im living out a 1988 chevy g30 rv and you literally saved my ass thank you so much for all the details and easy explaining all through the entire job.
Thanks for the video!! Haynes just doesnt compare to watching it get done. Got the old one off and new one on, fully reassembled in about 4 hours total.
Thank you for this video! I recently bought a 95 g20 Chevy van and need to replace the water pump. Between this video and the chiltons manual I bought, I should be able to do it. Thanks again!
Hi Eric, just a quick note on installing parts in tight and difficult to get at places. I do a fair amount of car repairs and on the modern vehicles the general lack of room to work in is often a problem and presents its own challenges. To that end, I have prepared various sized and lengths of blank studs, that I screw into the mounting holes prior to installing the part. Once a couple of bolts are installed, the blank studs are easy to remove. That helps to keep caskets etc in the proper places and additionally is a easy way to "find the right place" to install the part. Not trying to teach any chickens to lay eggs, just pointing out my way of doing things. Thanks for the many videos on your channel, as every day is a school day, no matter how experienced we are. Cheers from Indonesia. Keep wrenching man!
you really did an excellent job of explaining each step in the process and made this fairly difficult job look very routine. thanks for sharing these valuable tips and taking the extra time to video this procedure. also i would not have thought to put the teflon paste at the end of the 4 bolts going into the pump until you explained they were also going into the water jacket. reading it in a haynes manual is just not the same as hands on experience.
Love the hi tach spray. I use it all the time. Another trick with it is to spray a bunch on your hand and run for the bathroom. Looks like blood, freaks out the secretary
Great video. I've been dreading changing out the water pump on my '95 G20 for some time but the puddle grew recently so it had to be done. Only thing I did different was instead of putting the fan back on first then the belt I instead put the pulley on, used one nut to hold it in place, then put the serpentine belt on, then installed the fan. It made it much easier to fish the belt over all the pulley wheels without the fan being in the way. Thanks for taking the time to record this video.
I got a funny story for you, Years ago I did spark plugs on a Chevy Astro van for my brother-in-law. I got some of the plug from the dog house and some from under the van. I was under it and removed a plug and low and behold it looked brand new, It was because it was one that I just did from the top. I don't know how much blood that I lost that day but it was a lot. Lots of sharp edges on those.
I just want to thank you for this video. I replaced a water pump in my 1987 Chevy van G20. Your instructions were perfect. I will be looking at you for more information.
I'm glad the van you're working on is actually a GMC Vandura like mine (but a couple years older). I know it's the same thing, but gives me a little reassurance. I have to replace my pump soon, and this was a big help! Thanks for posting it...
just came across this and it is very helpful(2023) add one thing I'm going to install a new thermostat veery gooo video . no messing around ...Job done
I had the A/C compressor replaced on my early '90s van. The shop that did the work crossed the windshield washer tank and vacuum ball hoses during the project. It ran great for about 5 seconds until the engine sucked the washer tank dry. No long term problems, just pulled the spark plugs and blew all of the washer fluid out of the cylinders.
I’m in the middle of this job on my 94 Chevy right now. Thank you for this. Only took me 90 minutes to remove the fan shroud (rusted screws). I’m in for a long job.
how did you get the fan schroud off? did you disconnect the a/c line? i have a 94 too and the schroud comes in two parts and i could not get it off because of the a/c line. one guy on youtube simply cut the schroud into pieces to get it off.
@@bobrenaldo467 I remember it being difficult and not fun. After it was unscrewed I managed to push it in and bend and tilt it to squeeze under the AC line (towards the left side). I had my son pulling the radiator forward and pushing hoses out of the way and I not so gently squeezed it under the A/C. I just replaced my A/C so I was extra careful not to put too much pressure on it. It was easier to get back in. Hope you got it.
I had a 85 conversion van. AC never did work, had the trans rebuilt, alternators 3 (Autozone) and a water pump. Burnt a hole in the brake line changing the battery once. Brazed it shut while it was running. Ran great, sold it to a guy at a carnival.
I honestly thought that i was the only one that had a "gasket hammer" in my tool box.... the smallest Mac ball peen hammer..... PERFECT for cutting gaskets...... Thank you for showing these milleniels how WE did it back in the boomer day...... LOL.... (that means lots of lettuce .... right?)
Excellent video. I like the videos on old chevy or gmc trucks because I have one. Mine's 30 years old so I don't expect you'll ever see one that old up there in the rust belt. I'm in Florida. It's not even a restoration. Just old, lol.
I once replaced the water pump on an S10 blazer in the desert on a hot engine as the sun was going down. It wasn't terrible but it wasn't my favorite thing
I did every thing from under van . No need to undo every thing from top,especially on front and rear air thats working. Take fan off and lean against a rag on the radiator.Remove fan belt and then four water pump bolts. Make sure to glue gaskets on because its a tight it going in
Scott alan good to hear you did this the way I plan to do it (from underneath). what part number did u use for the pump? I found several different part numbers that vary in size
@@Machewching I'd say if you have more than 1 vehicle, take the water pump off and bring it in. But there should only be 1 if everything's correct while looking it up
I have an 84 GMC Vandura Van and whenever I have to do a job on the engine like replace a water pump or an alternator I remove the upper latch on the hood. After bumping my head about three times on it I decided to just remove it until my project is done. Only two bolts, Good for your head. ................................'Just saying Mike
i bought a can of high tack that you brush on and its black in color and man that was just more like no tack or slight tack in 1hr haha, i have since thrown it in the trash
My Dad was a mechanic in the 70’s and He would make gaskets using ball peen hammer. He also used a product called “Indian Head” Copper spray on head gaskets and all other gaskets.
Dont have to worry about the .080 extra body thickness with that 'Tough one' water pump thank god-- I prefer permatex for gasket sealer and it also holds it well too, the old school shellac works well. Pump probably rusted through from the inside due to that nasty anti-freeze or at least a contributing factor- always nice to have a van with no exhaust
'Vans are my least favourite vehicle to work on' I hear ya. I own one to get my dirtbikes where they need to go. Sometimes I want to just rip every piece of cowling, cover and panel off the stupid thing, weld a frame for the seat and drive it with the window down so the fumes don't kill me. It would be a treat to work on the stupid thing just once without having bleeding knuckles, crushed fingers or chafing rash hahaha!
A neat trick I learned from working on riding mowers and cars. Put the ribbed part of the belt on the rubbed pulleys and the top(flat) parts on the flat pulleys. Never had that fail me
Ah these early videos. Your mannerisms and 'way of talking' started reminding me like Red Green when he did the Handy Man Corner segment of his show. (except you know what you're talking about...and you're not always surrounded by old K-Cars.....) Have a good day!
Ha, did I get a chuckle when you said these vans are your least favourite to work on. I spent many years on the line with GM building those . Know how you feel . LOL
Nice video, I'm getting ready to do this on a 95 G20 and though I have changed my share of Chevy pumps, I decided to watch this before I start to be sure there's no surprises. Nicely done, one thing you should mention is how long it took to complete. That would give us amateurs a rough idea how long it will take us by taking your time and doubling it! LOL
Great vid Eric! I have a 86 jeep j20 360, that I plan on changing the water pump out on. hopefully its similar to the Chevy . I do know that the gasket is quite different ( one large beast that surrounds the entire pump) and it has a whole lot of bolts. Would you still recommend installing the gasket dry in this case? or would you use the gasket goop. again good job teaching.
The spray is to "glue" the gasket to the waterpump. The gasket will seal to the block without the spray. Also, the spray between the gasket and the block would make the next water pump replacement a lot more work to get the mating surface clean
Worst water pump job I ever did was on an older Ford van with a 302 outside in 3 degrees f with -20ish windchill and fairly heavy snow falling. ...you cant choose your family...
Awesome Vid! So glad I came accross this. Heading to get a water pump for my 89 chevy g20 now!! One question, I was told "you should always replace the thermostat anytime you replace a water pump." Didn't see this done in the video. Thoughts? or do you have a video on that element?
I love your videos Sir. I also really like your humor😅.....im currently getting ready to do this. I apologize for my ignorance in advance -- I was wondering if You think that the AC compressor can be bypassed with a smaller belt for this engine? Have a great day and I hope you have a wonderful Holiday season
