By far the best instructional video I’ve seen bc he takes his time and doesn’t just fly through all the information ! Great job! Definitely subscribing!

[@DarkTranqz]

This just happened on my 98' K1500 and I was so confused. I have never heard of a weephole before. After I got home, I noticed there was a pretty consistent stream of water leaking from my motor, and leading up to the bottom of the waterpump where the apparent weephole is (just did a flush two days ago and was running distilled water until I add the coolant back). I thought a bolt had vibrated out of the water pump or something 😂 I can now only deduce that the flush must have shaken loose whatever was keeping my apparently deteriorated seal, well, sealed. Cool. Now I know what a weephole is, and that I definitely need to order a new pump pronto. You guys have helped so much with learning how to work on different parts of my truck that I was ignorant about. Thanks a bunch, and keep up the awesome work! These are the best DIY auto videos on KZbin.

[@TSunshineful]

I took my 97 Dodge Ram van in for something totally different (dealers) and they said I needed a water pump. I didn’t believe them cause I had no over heating issues. Came here to watch the video. Going to get a second opinion some place. I’m a 71 old lady easy to scam.

[@erod4489]

Very good idea. I came to this video and determined my 1959 ford f100 pickup water pump should be replaced since coolant is coming out of the weep hole although its on the very top side of the pump not the bottom like he says. However my other concern is as it is an older truck and engine i believe the pump and fan is one unit which is why i think the fan rocks back and forth or has to much play in it. Perhaps yours isnt weeping out coolant but has a bad bearing like mine.

[@wyattandwill12]

You can also get a cooling system pressure tester loaned from Autozone or Advance Auto Parts which pressurizes the system and if the pressure gauge it had drops, you can see where the external leak is or you can find out if it's an internal leak. If it's an internal engine leak that means you have a cracked/warped cylinder head or a blown head gasket.

[@DavidMortaz]

Through video. The Heater Core on a 2000 Jeep Grand Cherokee has my hair on fire!! I flushed the heater core and the water flows fine and is clean! But despite both lines going to firewall being hot, the Heater Core stays cold !! No heat comes towards the cabin side!! Blend Door area is now cut open and they both work. Actuator also works and operates the blend doors! Could it be the failing Water Pump that's is not pushing the water w enough pressure?

[@danielareyes5937]

Awesome video. Very informative

[@iancontreras7688]

any ideas why a freshly replaced water pump is still leaking? I can't spot the exact location, but that weep hole sounds suspect to me. Seems to be just below the actual outside turning mechanism that is linked in with the belt. Very minimal, but I can see a small drip after a day of driving.

[@sammyidris1002]

I got a similar issue with my Subaru Liberty

[@josemeza2051]

My 01 civic overheats a little up past half when idiling after a while at a light. Replaced the thermostat already but have a sweet antifreeze smell when the engine is too hot. When I start driving the temp goes back to normal is that cause the water pump isn’t doing its job until I press the gas and it starts to pump again?

[@daby8399]

OMG awesome video... A lot of the stuff I knew some I didn't but I don't have a bad water pump obviously but I watched all the way to the end just because this dude got me really interested

My Accord has been sitting in door at a car storage for 3 years. I'm taking out of storage this coming Spring in April and putting it on the road, but first I wanna replace any worn out parts and I also I wanna replace my Timing belt Tensioner and water pump, along with a complete tune up Spark plugs, and wires distributor cap and rotor with the O-ring, cabin filter and fuel filter. There's also a Vacuum leak and an Evap issue with the fuel running either rich or lean, I can't remember. It's best I check all the Suspension components as well, and the Brakes and rotors. Maybe flush and fill the radiator fluid and Transmission fluid. My Accord has the original F22, with 370,000km with a few Aftermarket performance engine bolt on's.

[@skoomacat13]

So the gauge showing it at normal operating temp but a smell of coolant is an indication to look at the pump rather than head gasket? I was getting a noise when id accelerate that sounded like a bad bearing, only one that i havent changed is my water pump so im thinking it could be that? It started smelling like coolant when i got home last night from driving around the park and the bearing noise wasnt as loud as it typically can be. The engine did seem a little but warmer than i expected but the gauge is working and showing a normal temp slightly below the halfway point. Theres no coolant on the ground. Havent fully looked at everything but i couldnt see any leaks

[@mrnothing249]

[@1AAuto]

+mr nothing Thanks for checking us out!

[@nosoyono1081]

A quick simple way is to let the vehicle sit over night then open the radiator cap make sure you have coolant in it start motor with cap off let motor run a bet look in to the radiator to see if coolant is flowing if not you got a bad water pump or the thermostat is stuck ether way change both.

Hey my Honda Civic 2005, overheated when I bought it. I changed the radiator, thermostat, and the fan, but the radiator won’t hold the water when driving in hot weather the temperature goes to the roof

[@antoniogriffin7135]

TO KYO you changed the water pump? Did you figure it out?

[@engelsramirez4886]

antonio griffin the timing belt was barely hanging there. Also, the water temperature sensor was bad

[@twelve24twenty]

I’m literally taking my 05 Honda Civic to the mechanic shop right now to have a new water pump and timing belt put on , I changed out the thermostat and radiatior when I first got it and it didint overheat for a few months and then I took it to see family which is a 4 hour drive and about a hour before I got home it randomly started overheating again the shop diagnosed it as the water pump hopefully it works I’ve been dealing with this car for awhile now and from reasearching I’ve seen a lot of people have the same issue with this model car

[@engelsramirez4886]

John John my timing belt almost broke, but the piece that was causing the overheating was some called “la cebollita) that’s the name in Spanish idk in English, but it looks like a big screw

[@BeatMystic]

John John was it the water pump ?

[@khoayeuha]

I'm seeing coolant leaking below the serpentine belt but also out of the coolant drain plug(below radiator). Does the coolant leak travel from passenger side to driver side area? There are 2 puddles.

[@claytonstill2385]

It's more dangerous than a pot of boiling water. A pot on the stove isn't under pressure.

[@WellWisdom.]

So true.

[@NazrinKhanqs]

Thanks . Recently I changed my car nissan tiida 2011 radiator because of some leaking and after that my car was showing overheating when i drive 60 / 70 km. and i can feel my car was giving small vibration before the overheat indicator. So i do stop the car aside road again fill the water . I can’t see any external water leakage. A/C is working perfectly and heat is not working. I recently changed water pump too. I am tired of this pls can you advice me.

[@CJ-if1ry]

Hi. I don't have a leaking water pump, but I think the bearing might be going on it; however, I can't 100 percent pinpoint the sound, so I am not sure I should replace it (85k 2005 Toyota).

Help me please my next step is the water pump???

[@Giorobot]

Replace the cooling fan relays and temp sensor first

[@MrPaulSimone]

@@Giorobot That is the best "first" advice I've seen. The temp sensors and relays should always be tested before thinking it's the water pump.

[@buzzed4603]

What if the car is over heating but the radiator cap isn't hot at all nor the hoses besides getting close to the thermostat

[@1AAuto]

+Nighel It is possible that your thermostat is not opening up so the coolant is going through the hoses to actually get hot.

[@BAND-MAID-USA]

Could this be stopped with a Stop Leak product?

I replaced my radiator and thermostat. and I have no leaks and my fluid is full. I seen my fans come on but they come on for 10 seconds then shut off. What could be my issue?

[@1AAuto]

+sean watts The fans aren't always going to turn on it's more so where they turn on as needed. But you may want to have that looked at and diagnosed.

[@MrPaulSimone]

Why was the radiator replaced? If temps are normal when moving , then the radiator was doing it's job. You most likely have an air circulation problem. Which is why it gets hotter when stopped, and not when moving. The fan(s) are responsible for air flow when stopped or at low speeds. That should be a cooling fan, fan relay, or fan switch issue.

[@juggalogamer8541]

That's the kind of smell that I was getting and also when I stop the car that was like smoke coming out from a leakage somewhere where the coolant was going in also it's making like a loudest grinding noise and one of the police is like kind of off looks like the water pump one so I'll probably just go ahead and replace that

@ThePariss333 NP It pretty much depends if you run your vehicle on water or coolant, naturally it will last less time if you use water to cool your engine, I have a few forklifts which I learned about this for the first time myself. I actually need to change another one sometime tomorrow. Yes all engines have them. they are a bit inconspicuous to notice them on the engine especially if you don't know about it.
