Hopefully this will help people out! #ObsOnABudget . I also replaced the upper & lower hose, radiator cap, and thermostat gasket.

Best informative video I seen. I need to replace mine on my obs, second one in 3 years. A shop did it last time but I don't feel like spending 400 plus to replace it at a shop. Thanks!

Love these videos, my 13 year old grandson changed mine after watching this.

Thank You!!! finally a simple easy to follow vid. Nice tip on the fan studs!!

Short, sweet, and to the point. Thanks!

This the simplest yet best video on changing a water pump thanks bro 💪🏽

Nicely done fellas!! A good refresher video before tackling mine. Thanks for posting.

Best intro music ever, DM is the best! Listening to Violator while I do this damn water pump!

Excellent tutorial!

Thanks brother for the quick how to

IM DOING THIS TOMORROW THANK YOU FOR THE VIDEO

Good video, watched before replacing my 1994 5.7L which had totally failed breaking the belt and dumping coolant on the ground. Couple of things I ran into to be prepared for -- I was worried about 30 year old water pump bolts coming out, they came out no problem but only one of the four 1/2 inch drive 14 mm sockets I had would fit the narrow opening around the bolt head so check that before you start. The four bolts holding the fan on looked in good shape and didn't think they would be a problem so of course they were. One came right out, another after some work, the last two no luck. Had sprayed all them ahead of time, tried smacking wrench with hammer many times, then vice grips and smacking harder, then heating them. The last two would never budge and ended up cutting them off with a hacksaw blade (cut the nut down the side so you can get the stud out). The threads are M8x1.25 and I used get bolts to replace the studs/nuts for those two as no parts store anywhere near. If you are putting on a new lower radiator hose, my radiator end spring clamp was not accessible until I pulled the radiator free (you don't need to disconnect the trans lines, just move the radiator over a bit). My truck very common build, Delco GM part number for pump 252-719, belt 6K966/88932795, and lower hose 26207X 88908904.

As soon as I heard the dude first talk I knew this was the presentation I was looking for.

Excellent video

Waiting for the parts now, my 93' K2500 Suburban is getting a new pump and a 4 core aluminum radiator with dual electric fans. Will help it out a bunch in the 100+ degree days here in Arizona.

Nice man good shit. 💯

Loved this

You the man 👌🏼👌🏼👌🏼

Very helpful

Really good video

Orale Homie thanks was a Long time i did this water pump remove from my 1980 Chevy blazer k5 2wd custom deluxe blue homie and thanks I totally forgot how to remove the fan just to start 😂so yeah I change the water pump 10 years ago

My rtv sealant is curing right now, thank you so much for this video. The water pump bolts came out easier then the dam oil pan drain plug, lol. Lots of life left in mine, she’s a tbi 1st gen 93 c2500 rwd. filling up with water tomorrow, starting her up and seeing how she runs, cheers :)

I got a leak right in the front center gonna try replacing this and hoses around hoping to fix the leak

Good short simple video, if u do more videos it would also help if u put in what size socket u are doing for things ,lol I'm watching the video as I work

Nice

Nice! Need to remove both steering pump, water pump & A/C compresor in order to clean the block from an oil leak from the manifold gasket. Think there Would be trouble if water pressure goes into those water pump holes into the block?

quick to the chase!!!

Nice I did mine today with your guidance thanks.

What brand water pump did u go with I see them priced anywhere from 40$-130$ not sure what to go with

Looks like you put some blue material on the gaskets and the two upper screws, but no mention of the material or how you applied it, nor if you allowed it to get tacky. How much torque on the four bolts? I am hoping for no leaks, so these details are important.

What did you use to cover up the hole on top ? Mine has 2 and I only need one because I only have to connect one line

Hi What’s the thermostat best for 89 5.7, I’m having over heating issues.. its time to do some shopping

You have to put sealant on the gaskets?

Great video! How do you know if it's a reverse or standard rotation?

I did that process for my studs but a bolt got stuck on one now I can't get it off. Any tips?

Background music on point fam.. i forgot i was watching and started freestyling for a sec. Great video and quality of work

I have an intermittent coolant leak in my 95 C1500. I thought it was the bottom hose connection at the water pump because sometimes coolant runs down the backside of the hose and drips when it gets to the low point of the hose. But I replace hose. Still leaked. Replaced clamp. Still leaks. I'm wondering if the water pump could be leaking from one of the bolt holes that is behind the hose nib and running down the back of the hose. Or, if it's leaking from the weep hole, would it run down the back side of the hose? Only leaks after the vehicle has been running and is then parked somewhere. And again, not all the time and usually not right after I park. Usually doesn't start dripping until after it's shut down for a while. That what keeps me thinking it's the hose/clamp. But I'm at my wits end here. Any possibility it could be leaking somewhere other than the hose itself?

What are you using to hold ur gasket i place?

My 1990 chevy overheats with the thermostat installed how do I fix that I run it without it for now

🔥🔥🔥

How did u do such a nice video and bot show the top hose deal

Fucking amazing video! Straight to the point

What does mean the yellow dot on the fan pulley???

No bullsh it was straight to the point

Why no rtv on bottom bolts, they go right into the block

Were you get that speedometer

OBS 4LIFE!

Why no reviews on bottom bolts, they go right into the block

Lucky duck with your overdrive

if you still have the truck you have a severe under voltage issue with your charging system. voltage should be reading just above 14Vdc

Is the motor 400 or454?

How do you let the air cycle out just leave it running

Very nicely produced guide, but I have one criticism. I'm mostly looking to compare how everyone handles their gaskets and RTV (some say just RTV, some combine the two, some swear by just gaskets), and you skipped over that part entirely.

How much would someone charge for this work

Great video Bro. My pump just started leaking on my 93. I'll be replacing the pump and fan clutch. I assume it will be simple too. I subscribed to your channel as well. Go check out me painting my OBS and replacing the interior. Thanks again.

Sorry Buddy, that may be for '88 to '94. '95 and up are different.

Great video, but the awful music ruins it and makes it so we can't hear you

You skipped a few steps … so no not a complete…help….

lets see you skip the gaskets and skip showing take out metal lines from raditor

Annoying music and not much description and no bolt sizes making the video uninformative

State the size of sockets, don't get in a hurry. Aside of that, its like a blind date.
