Mazda CX9 3.5L-3.7L Water Pump Timing Chain Compression Test 

That's what I'm talking about....that baby sounds excellent on the highway!

i just took apart a 2012 because it sets a p0016 code as soon as you fire it up. turns out the water pump bearings are bad and the sprocket moves all over the place. never lost any coolant or made any noise. just a timing code.

I just ran into the same issue Dealership didn’t mention replacing the water pump. But they said I needed a new motor. But changed the oil n the motor seems fine. I’m going with yr info just change the water pump

the Chrysler/ GM puller works perfect

I am almost done with this job but I've spent 2 days trying to get the serpentine belt back on. Did you have any problems with that? Using the old belt, its like 1 to 2 inches short even with the tensioner loosened all the way.

Thank you sir.

Have 2010 my sister's. The mechanic said that one of the heads are cracked, without even taking it off. I know you can only tell if it is cracked by taking the heads off and seeing a crack. The compression test, like you said, will determine if the gasket has failed for it is designed to so that it will protect the head. I have the mazda a my place, the waterpump in the crankcase is a new one to me. Thanks for the input looks like I got a few extra tools to buy along with the complete chain and gear assembly. Any other surprises to replace the head gaskets?

What was the first symptom of a leaking pump? is the fluid getting out of the engine? does it flow immediately to the oil pan? my mazda cx9 is 200,000 miles. Works fine. the fluid is not diminishing. clean oil.

My daughter's 2007 BMW X3 was totaled after being rear-ended... found a 2011 CX-9 touring in really great shape for sale ($7,900). 150K on it- very clean, according to CarFax it was dealer-maintained up until 80K then sold with no maint info thereafter. Took it for a drive and it runs GREAT- no noises/rattles, everything works..... then I get home and learn about the water pump issue. Now I'm concerned. I am fully capable with a wrench (owned the BMW X3 for several years and had to do some pretty involved work on it (shocker) and it runs GREAT). Knowing I can do the WP job myself- do you think it is worth buying this car with it already having 150K on it? If well maintained- how long can expect this car to keep moving on down the road? Any other issues to be aware of? - GREAT video BTW...thanks!

SKP water pump from eBay. Evergreen brand complete timing belt. Are these good replacement parts?

Great job! I'm about to tackle this as well. How much time do you have invested from start to finish?

Where'd you get the parts? Not seeing a bunch of quality kits available

Awesome video! Do you happen to know the part number for the longer bolt?

is it rare to be able to save these before the coolant leaks into the engine and trashes it?

Hola amigo, soy de la CDMX y voy arreglar el lote de una mazda cx9 2009. ¿Podrías compartirme el diagrama de los punto de tiempo? Por favor

My mazda cx9 2008 300,000 km mileage. The route is 4 km. The check engine light comes on. It stops for 15 minutes. I'm moving on. Everything works fine, engine shows no temperature increase. Another 2km I hear the cooling fan, after a while again. I turn off the engine, I don't know what's going on. The temperature does not exceed 90⁰C. The engine ran completely silent. There is no fluid under the hood. Mud on the cork. The oil dipstick shows 2-3 liters above the good condition of the oil. The car is at the mechanic now. In a few days I will want to change the water pump and timing belt. Clean the oil pan and valve covers. 2 oil changes and engine flush. I hope I didn't damage the engine. I was driving very slowly. What do you think? Any chance the engine isn't dead?

Hey, hoping you are still checking comments on this vid. My girl just got her 2012 cx9 back from the dealer. After it's 90 k service. They said they spotted a coolant leak that had left a trail down the back of the block from where the water pump is. They said that at this point the car was toast because it would soon fail catastrophically and dump.coolant into the engine turning the oil to sludge and destroying the engine. They said that there was no fluid infiltration yet but that it was still not worth changing the oil pump because usually when they remove the oil pump they find a crack in the block. Yet tubers seem to repair this problem even after there is leakage of coolant into the oil. Do you have any advice? Dan

will an aftermarket warranty cover my cx 9 water pump and engine damage?

How did you go about timing the engine before removing the old chain?

Im having a hard time convincing a mechanic to do this repair. Is this expected? Both mechanics say that its not worth spending 2.5-3k on a car thats worth $6k at most.

I have a 2010 with 165k miles on it and just had the water pump failure. Sounds like I'm pretty lucky to get 165k miles out of it before the failure. I have it at my mechanics now. He confirms the engine is ok but will need the water pump and timing chain. I'm trying to decide if it's worth it. Any advice? What would be a reasonable cost to replace the water pump and timing chain with all the other parts that are needed for the job?

Can this failure cause no compression??

Is this the same for a 2015?

Can't hear you
