Water Pump Fail

This one is a continuation of the cooling system overheat video, here is a link

Many of you pointed out that the water pump could be at fault and it just so happened I got this car in a few weeks ago with this exact problem.

I hope you have as much fun watching these as I have making them.

Stay dirty

I remember from an old Chevrolet manual (1964 Corvette?) they recommended pinching off the upper rad hose and looking for/feeling a surge of coolant when it was released. Thermostat needs to be open.

@seniorjohnl A few people have mentioned that technique but I've never had any luck with it. Thanks for the comment.

Hi just a question, every time I switch of the motor the engine pushed the water into the water bottle. At least 2 thirds of the water get pushed trough the over flow in the water bottle. Can someone point me to a direction where to to look. It is a 1999 VW Polo

[EricTheCarGuy]

@silvermecer Honestly that may be normal, see the video I did on 'overheating' to see how the overflow works for a better explanation.

[kenman1717]

were you concerend that the metal from those impeller blades are in the engine somewhere? you mentioned over heating on the highway but not otherwise. thats what my truck was doing last year, but only after i put grille inserts in, to cover up my broken grille. after i took the upper section of insert out, it didn't overheat on the highway. but i cleaned the mud from rad/condensor and put in a new thermostat, it actually started running about 10 degress cooler.

@kenman1717 Not at all as they pretty much turned to dust, they didn't just break off so much as rotted away.

hey, Eric, another possible cause for the wear would be if the owner or another tech had mixed 2 different types of coolant, in other words, mixing ethylene glycol with the high mileage antifreeze, such as dex-cool, together. just a thought....

@silvermecer ey man. take your car for a ride 20mins or so. park it in a dry place. and look if its any water under it, if so, check where the leaks come from, often a line has a tiny hole that leaks all the time, but might be hard to see.

Or u can try radiator block, and add new cooling fluids with it, bleed it and try that.

Good luck tho ;)

[silvermecer]

@EricTheCarGuy I need to fill the water bottle every morning as it is empty. May it be a bad heat gasket on the water flow on the heat? I have already changed the water pump and bled the system and replaced 60/40 antifreeze to water. Still the same problem.

[MrBushchicken69]

@silvermecer i also have the same problem please tell me did u fix it and what was the actual problem with it

[suprakilla2JZ]

That engine wont last long.

[dallasfignrocks]

antifreeze keeps water from corroding your motor so i bet the owner of the vehicle kept only adding tap water until it started corrode things in sided the car

note*

you are only supposed to use distilled water in your antifreeze because tap water leaves water deposits in your motor witch over time can plug stuff up

[dallasfignrocks]

if you aren't getting any heat and your overheating its a sine that there is a flow problem in your car, doesn't mean its a bad pump cus it could be other things like air in the system that needs to be bled

[Rafe850]

Hey Eric I dont see where you talked about the ECT sensor Got a D16y8 1998 civic ex sensor is on the block just below intake manifold, and the other sensor on the thermostat housing cover could these malfunction and cause your vehicle to overheat

[dgr8zod]

Next sensor in vehicles; temp/vane switch in the upper radiator hose. Temp above x degrees, the vane isn't indicating flow, shazzam, a light comes on..

Water pump just went bad on my 4runner. NOT FUN, it is buried in the engine bay with the timing belt. Parts alone are roughly 300 bucks.
