Sealing a Water Pump Leak 

You need to have antifreeze all the time to prevent corrosion …don't wait till winter!

Thanks for the truck ride....lol, I have a leak have to put 16 oz a day in my radiator...

I think I need to try this, I changed my thermostat the other day and noticed the leak still going, I’m pretty sure it’s the water pump now, thanks for putting this together!

I put a brand new pump in only to have the pumps bore at the heater tube inlet not want to seal and leak just like that I even used the $15 Mopar o ring then tried black rtv after cleaning and let it cure for 24 hrs . Replaced the inlet tube which required removing the intake manifold to get the tube off only to still leak because it's the Chinese machine work. I'm going to try some high temp red rtv next I don't feel like pulling the pump it's a pita to drain the system without making a mess . I'm not sold on putting stuff like aluma seal into my motor since it might clog things I don't want it to .

Course ground black pepper will have the same affect for a temporary fix as well, and most people have that in their spice cabinet.

Thank you for taking the time out for posting videos like this. It really helps.

I tried Alumaseal on a 05 honda civic because its leaking from the water pump compartment. At first it was an unsuccessful fix, leak continued and i'm left with a leaking cooling system. $300-350 is way too much money for a water pump replacement. And DIY fix is crazy complicated without access to a shop. But have been using vehicle for local short trips and keeping up with coolant reservoir that needs to be filled practically everyday. Today after 200-250 miles i check coolant reservoir and it's at full level and drove car all day, no leaks. Amazing. Gonna monitor to see continued Alumaseal leak repair. Will post any changes.

Anyone curious, I just did the 2 tsp coarse black pepper in water, For an 2002 Avalanche seeping water pump. This partially worked and got me to Walmart, bought K seal and waited 45min to cool. I then added k seal and a bit of water..NO Leaking 🍻

Coolant is what lubricates and prolongs the life of the water pump. If you run mostly water, water pump will fail much faster than typical life expectancy.

Just put in my water pump back in December and here It is June. It started to whine along with metal on metal scraping noises as well as a leak all down the front on the harmonic balancer around the bottom of the engine. Green coolant began to pour on the carport, i guess out thw seep hole. I am having to put in another one on Friday. I oiled the inside of the water pump with penetrating oil for the berrings before I installed it and by closer observation with the belt off the pump spins like normal but this seems to be a seal issue obviously caused by the Blue Devil gasket sealant. White oxide residue all around the bottom of engine. What started all this, was my head gasket leaking coolant in a combustion chamber throwing misfire codes and cause erratic idling and driving so I had tried the Bars Leak and it didn't work so i got the Blue Devil head gasket leak selant and it worked and is sealed, runs without misfires, no codes in which i was getting on a consistent basis. It has been well documented that BV will cause water pumps to go out, along with other mechanical components. Well, Let's try it again and see what happens with the new one.

Great job on making this problem-solving video. Big thumbs up and subscribed.

I have a small coolant leak comming from the water pump area ima try this method and get back to ya ! Thanks for the vid

If it is leaking at the pipe first your lucky, second replacing the pipe is cheap ($15.00) and realitivly easy. It is never a good idea to pour these substances into the cooling system. Bite the bullet and buy antifreeze !! Water has a lower boiling point. Coolant will also prevent rust, rust is causing your leaks. Using just water will destroy the engine! Also the gunk at the beginning was oil in the cooling system...BIG TROUBLE$$$$$$$$$

$350 to replace a coolant pump is nothing compared to what it would cost to fix a HEAD GASKET LEAK. That gunk build up on your radiator cap could mean you have a HEAD GASKET LEAK which would also cause low coolant levels as well as engine misfires.

thank you good buddy.

LMFAO!you sir are hilarious with your observations!good luck!i currently have a water pump issue but i don't believe it's a quick fix,positive i will have to replace it but i have a 2 year after market bumper to bumper warranty,so i'm pretty sure i'm covered!

So the alumaseal it really works if so I'm have to try it out because my truck recently started leaking like that

The 5.9/5.2 is the easiest water pump to change and is cheaper than $350 if you do it yourself

Thanks for making this helpful video

“350 for a water pump is a lotta money..” I just got a quote for $1,500 for mine 😭

My 2003 astro van has a leak from the water pump they want 400 to replace it, i can do it myself but just had rotator cuff surgery so i cant lift anything heavy for months so im going to try stop leak

Take care of your truck they don’t make em the same anymore✌️

I have a 2011 ford explorer with a bad leak but I was told that seal coolant want work I need a new water pump replacement

Questions... So you only used water after adding the sealant and then drained the water to add coolant? Or could I use 50/50 coolant and not have to drain? I am not sure if you used pre mix or concentrated coolant when you mentioned you needed to add it and i just want to make sure i do it properly. Thank you!

This is a temporary fix at best. As long as this is a commuter car and not something you will really Drive long distance it will be okay. Usually when a water pump starts to leak it's because it's failing. Oftentimes through the weep hole. There are lots of aftermarket water pumps that are inexpensive with lifetime warranties. If the car has been good to you be good to it and invest a little bit of extra money. If you drive a car until complete water pump failure you may be doing irreparable damage to the engine

Sometimes 2 cans needed. I've never had a problem using a "Alumaseal" on water pump full size engines (except for Cadillac) if your heater core clogs try reversing the hoses on firewall. Old clogged up systems may not work so you will have to start with a chemical flush. Also if you loosen the radiator cap it will not pressureize and allows the particles to stick in the pump seal...then after 100s of miles tighten it up. And as for Subaru(should be splet S U C K S) the 2.5 box engine is a factory blunder that they supposedly fixed in 2003. As are several other Subarus on newer models. Ours continued to over heat so i drilled a 1/4 inch hole in the thermostat. We only buy full size chevy now.(since ford ruined 100million engines).

I've been quoted $1200 for a waterpump replacement i really need a quick fix

Water is the worst for your radiator and pump ?

Flush the whole system, Change radiator, water pump, cap, flush reservoir n refill

I have a 1987 Toyota corolla leaking water how is it able to be fixed

thx fa dis i have a chevy water pump leak hope this help

Did u put regular coolant back in it after u used the stop leak? I hav a 06 chevy Tahoe n I'm usin water mostly cuz it's leaking from the water pump. It's just dripping down behind the water pump on the passenger side of the water pump. Will it help that for now? I'm tired of using water cuz it's dripping on my belts n causing the squealing noises here n there

glad you fixed it, although,,,,, there could be an o ring right where the heater pipe fits in, could just be a bad o ring, i believe my ford has that, best of my memory, although, it's been a while since i changed my water pump on the f150, i could be getting all my parts mixed together in my brain, lol.

I wonder if this will work for my Nissan Altima. It just started leaking a couple days ago and as time has gone on it appears to be getting worse..losing water rapidly. Oh ! and the build up on the cap is from cold starting and driving instead of letting it get up to operating temperature them driving and who has the time to let it sit and warm up these days 😂🤣!!? It's called condensation. I will go into my local auto parts store and see if they have this "Stop Leak" today.

I change my water pump but it's still leaking water what do you think the problem is its a 1996 Cadillac DeVille

What happens if a The water pump clutch doesn't work?

You've got to learn to work on your own cars people. Its not that tough. My pump just started leaking. Never did I think about taking it somewhere

Will this work on my 2007 Chrysler PT Cruiser?? I got an estimate on mine, and you think yours was high?? My estimate at 3 different places..brace yourself.....from 1240.00 to 1550.00!!!

Also water pumps don't cost that much. It's the labor. Teach yourself how to replace them , I did

Step aside, I got this.

It worked for me but I think need carry water in case it happens again

Its a ram change ther pump just did mine!

Good video but ill tell you no lie you got me cracking up laughing. Moran that kilt it .

It was not a mystery leak, in the beginning there was light gluish like material around the inner antifreeze cap, and the leak itself from the waterpump area hose/tube. Also heater core clogged are major signs that in past someone put engine gasket sealant via the antifreeze tank to either stop oil leaks or other leaks in engine. . . . thus messing heater up, substance around antifreeze cap, and leak on waterpump hose. Leak is not bc of sealant its bc of inner part flows of antifreeze clogged at waterpump. When heats up it flows no problem but when cools down it hardens seal so it pours back out by hose since it has no where else to go.

That sealer shit is all temporary none of it is a permanent fix it's only to get you by til you can replace the parts that leak.

Do you think this could work on a 05 Suzuki

Hey nice video, I have 2012 chevy sonic and got leaking on water pump, can I put this alumseal on my radiator reservoir?, because I don't have a radiator cap on my radiator, only hose from radiator reservoir. Sory for my bad English. Thank you

Mosquito mobile 😂😂😂😂

THANK YOU

Could you use two bottles?

$3.20 with tax, what a rip off?? ..hey, it sure beats the hell out of $350 for a water pump.

350 is cheap. I’d take that in a heart beat. I was quoted over 1k. Over priced $500 water pump and 3 hrs of labor at 500.

You need new antifreeze.

It is better if you take the thermostat out first

pull the stem add a new oring theres is your stop leak

so will this clog up?

Yea i need to know because my radiator bas a bad leak and now my water pump is leaking. Will cost $850 to fix amd i definitely need fixed asap

I have a 99 honda accord my water pump is leaking I can't even drive it up the road without it running hot!! Tried Bars Stop Leak didn't work!!!! Do you think I should try this instead???

Dodge water pumps dont cost nearly that much. If it was the tube as in your case a new tube would set you back a whopping 10 bucks if that. Those pumps are a cinch to replace but instead of jerry rigging and causing more issues down the road should nust replace the darn thing. Do the labor yourself.

How long did that work for?

He need to flush that radiator it's full of gunk right away

Is this alumaseal safe on all vehicles? I need to use it for a lexus gx460

$350 is nothing. My waterpump replacement cost is well over $1000. Calls to remove the whole engine to replace.

Hey you left out the bathroom stop....

Is it still working?

Should I use antifreeze instead of water with the powder ???

I drive with water only

will this affect the Heater core? I have a slow leak from the water pump on my Silverado 2004. Thanks for the advice

Honestly I wouldn’t recommend it thru time that stuff will clog up your radiator.

I have a 04 Honda will this work, and is it some how connected to the radiator? I know nothing about cars just that mines is flooding like the Nile river

you need to purge any remaining air from the coolant system with the engine running before you put the cap back on.

ok

On my 2000 chevy v8 5.3 it was major leaking suddenly. I removed the old pump it looked very new and it spun nicely. It had 2 aluminum gaskets i believe one blew out. The Alumaseal did not seal it and Normally i have 99% good results.(poor mans fix) So i got a new pump. I used 2 C clamps on pulley wheel and pipe wrench. Rapp the wrench hard. My old pump spins smoothly and no bearing noise.

same here, they do want $330 for the water pump

I can fix it. if your in the 209 . not my profile, so never mind the pic.

I need something to seal a small leak for water pump leak

How long dose it last you and is it safe

where the fuck do you live that a water pump cost you $350? holy shit! i just got one at oreilly's for forty bucks.
