1999 Chevy S-10 4x4 4.3L Water Pump Change




What do you think about this video?

Bryan J. Smith: Thanks!

Tony Pina: thank you for the video it helped men a lot easier

Alvino Melgoza: Thanks for making this great video,you did a great job!

Mike Blake: Short and sweet. Thanks

Jeff McDonald: Will this procedure work without removing the fan?

rounddancefan1: I have a 2000 bravado same motor 4.3L Vortec, I just bought it, well everything was ok, we recently went threw a car wash & ever since the belt has been noisy, I replaced a idler pully top pully, but still it is so noisy, the sound seems to be coming from the A/C pump, the belt looks fairly new,, we also took the belt off and started it with the belt off, it was ok, but soon as the belt went back on, it start making noise, also once in awhile we smell coolant inside the bravada and hear water slushing around inside the dash. thinking about replacing the water pump & taking off the A/C unit & put a idler pully the way your is set up. Oh also thinking about replacing heater core.

mandingocell: very helpfull video

iamchevyman5: why do you keep your fan shroud if you deleted your fan?

David G: This video help me to replace the water pump on my 1997 K1500 4.3. Not quite the same but close enough. One whack (or two) on the fan nut didn't do it for me. I kept at it for 5 minutes and grabbed the belt to help it stop moving but finally got it. The hardest part was getting the bolts started on the replacement pump, it's tight and down low on the 4.3. TYVM.

mikevmpr3: i have a fan attached and am having problems removing it. what do i do?

Shockern003: how long did this take you?

benekaiwi1: No my s10 is a bit newer than yours. My s10 is a 2003 zr2. You need a special tool to remove the fan.

spelunkerd: I hope you like Alberta, Ben. I live in Lethbridge. If you live in Calgary you'll want that fan to keep the engine cool in city traffic. Summers at high latitude have long days, but here on the prairies we get our share of hot days as well. What's your day job?

FergusAndRex: @TeDuaMalakie The EGR motor is front and center on the engine...if it had teeth, it would bite you as its almost pointed right at you on the front center top of the motor. As for the knock sensor, probably hiding under the exhaust manifold screwed into the block, probably not far from a freeze plug. Thanks for the question.

benekaiwi1: Wtf. Fan shroud to water pump? You skipped the fan clutch and fan removal. Not very helpful eh.

TeDuaMalakie: hello, i would like to see if you know where both the knock sensor and EGR sensor are located in your car !as long as i have the same engine of yours in my 98 blazer but i'm really having hard times to locate where those 2 sensors are really hiding . thank you .

SnoopofAbenberg: Thanks for the info.

AutumnsList: to loosen the belt you would go to the left, but if you push it to the right it will actually tighten up the belt even more. now place a huge wrench on the shaft nut and smack it to the left with a little sledge hammer while holding the belt tool to the right (two people make this easier, but i did it with just myself). Note: I also put cardboard on both sides of the wrench so it wouldn't damage anything. I also hit the wrench to the right a couple times, which always seems to help. good luck.

walshmonster2005: I had to do that on my 4.3 V6 a couple years ago! Great running engine!

Tom chevy350: u sould of painted that pump . it will rust . i just pump one on my S10 4.3

Ricky Sharpe: Radiator could have a leak. Hoses could not be securely placed.

Turbo231: @kolbpilot Not sure...my truck never came with AC, so its just the factory idler pulley.

Turbo231: True...however the stuff in the video is "mixes with anything".

Mario Fontalvo: Nasty hit your radiator core took there when pulling out the water pump!

VE9REJ: Good Vid dude , Man I miss my old s10

Turbo231: Make sure the system has no air bubbles impeding flow, make sure your system didn't kick up some debris that slowed down the radiator, make sure everything is somewhat clean on the outside too. There should be plenty of cooling capacity on the S-10.

Turbo231: @kolbpilot I would do the auxiliary fan...they can be had for about 100 bucks, you'd only need a manual on/off switch if you are pretty much the only driver, but mechanical fans are loud and annoying. This truck is an eastern seaboard truck and did fine, but with no AC and not a lot of hot city driving, it was no issue. My 1991 S-10 2.8 also had the fan removed, but it had AC and I used a cheap fan to pull air across the condenser, it was more then enough.

TeDuaMalakie: @Turbo231 paused this video on 1:31 ,right there ..i know what u talking about ! apparently we have slightly different engines, mine does not have anything right there except the thermostat hose,i do not even have any device looks like that installed on my engine. my engine is 4.3 vortec 4X4 , its weird tho.. . anyway thank you , i have annoyed you enough so far ! :-)

Veikra: @TeDuaMalakie on my 1500 i didnt feel any difference in power but it's a LOT quieter when accelerating and it warms up faster in the winter.

Turbo231: Yes...and they aren't even nuts...they're bolts. Oh well. Nugget for the "best of" videos. :p

ducklandwikeno: Oh I meant the raditaitor dran plug.

Agnar_BurnsAll: i despise factory clamps with a passion!.

Turbo231: Probably 2 hours...hard to say, never did it before and shooting video while working takes up a lot of time.

Turbo231: @Veikra Agreed. Got tired of it sounding like a 747 sitting on the tarmac on a cold winter day.

jeffinpickering: Good video; nice work. Add: bolts should be checked/re-tightened once warmed up to temp. One other thing folks may find is that the system may have to be burped more than once to get all the air out; a good idea is to get the passenger front higher than the driver's front when burping.

Cuatrostudent: Hi nice video. I have a 98 chevy blazer, and its leaking water I belive from the water pump. is it the save procedure? thanks for any suggestion you can give. Thanks Vic

Turbo231: Yes, the pump leaks when it wears out. Same procedure.

NRP1991: GREAT how to videos, some of the best on here by far!!! 5 Stars!!!! keep them coming

rich jania: How dose your truck not overheat with out a fan?

ducklandwikeno: My radiator on my 1997 chevy blazer was hell to turn , but you can get it out .

Gary DuBois: Nice video except YOU DONT TELL HOW TO GET THE DAMN FAN OFF! WHICH IS STEP NUMBER 3

Turbo231: @TeDuaMalakie Kinda...I mean, nothing really seat of your pants feel, but of course, power not used to turn the fan heads to the rear wheels. We do it to all RWD cars we have...traditionally we put in an electric fan, but given the lack of AC, this didn't need one.

Turbo231: Its ok. I had it on my previous car and my father has it on his 2000 S-10. Does it add anything? Not really, maybe a bit louder at WOT. It does tend to soil the MAF sensor, I generally have to clean the sensor every year.

Paul J: This is the first vehicle I have seen that comes without a fan. What the F?

Turbo231: Spray some thread lubricant and figure out a way to keep that pulley from moving.

Bryan Martineau: I have a 2002 chevy s10 4.3 liter. Is this pretty much the same layout? Im not too familiar with mechanic work, but I do have access to all the tools. Following this guide, do you think I should fix it myself?

Jonathan Thompson: Thank you Ben!

Veikra: @Turbo231 :) I also did the heater return to water pump instead of to the radiator. That way it reheats what's already hot until the engine is warm. It also helped warmups.

Invisiblepanda: the u-joint was easier >.> lol good video

Turbo231: Should be about an hour if you take your time. It probably took me longer, but setting up the camera and such takes quite a bit of time. If you just go right at it, it's not that bad.

Vet: When I graduated High School, all I wanted to do was kick back and relax without having to do any homework. But I realized I have no money to do anything fun. So I went to a San Francisco Vet School to get trained to make money. But seeing your videos, I am gonna be an internet marketer on the side. Let me know if you have any tips. Thanks.
