Back in May with friend of mine's help i replaced water pump and all other items in t-belt service with new heater core and all collant hoses.Parts were from Blauparts and we used t-belt tool.That pump started leaking few weeks ago from bearing, got new one installed 2 weeks ago and that one is leaking again from bearing.In process i also installed new radiator since small nipple on top broke.I can't believe that i got 2 bad pumps in a row.
Is it possible that pressure in cooling system is to high?If it is high why would it happend and what would be common symptoms.I am guessing that i would need pressure tester for this.Any specific tester that you guys have used?
I am getting so sick of this car that i am about to give up.

 

Did you get both pups from Blau? I wasn't crazy about the quality of the pump I got from them

 

What do you mean by not being happy by quality?Yes both pumps are from Blauparts,under warranty.

 

It just seemed crappy.

I had bought a Bosch WP before I found the Blau kit so I had 2 pumps when it came time to do the job on my 93 90q. I ended up using the Bosch because the Blau one was harder to turn and seemed cheaper.

I also know that the guy who had my Cab before me had a Blau WP go bad n him too. There's info somewhere on here or quattroworld . Search for posts from Cab_and_wagons - he owned my cab.

I actually ended up putting my extra Blau WP in the cabriolet recently. It seems okay for now.

 

Any other ideas on why this could be happening?Cooling system pressure!

 

Blau uses Meyle pumps which are low end.
INA is the OEM but twice the price but judging by your down time it would have been worth it. I don't care for fixing things twice in short time.
Hepu is a quality German made brand which is what I used.
When it comes to parts you get what you pay for. For an item that is hard/time consuming to replace just go OEM.

If your system was clogged your temps would be off the chart, are your temps normal?
The system is really simple, the thermostat just opens when at temp to allow the flow.

 

Hi, If your engine is 2.3. Tension of TB are so important to WP and life of TB it self. If you set too tight to the WP when install the only WP or with new T/belt. I't will be failure bearing on the WP. Therefore, check the TB tension after installed. HTH x19

 

Blau uses Italian brand water pumps in V6,which is what i have.Temperature is fine,like i sais all components in cooling system are brand new.
Due to time constraints i had local a/c and radiator specialist install new radiator for me.Never again will i have someone else do work for me that i can do myself,since he "forgot"to hook up my radiator fan wiring back to sensor.I just noticed this today when i was under the car for the first time this week trying to figure out what is goin on with water pump/coolant leak.Of course he left some clamps little loose to.
So after tightening everything up and connectin fan sensor so far so good.We will see what next few days will bring.
One problem is that this is my daughters car and i hope that car wasn't overheating.Do you guys think that the fact that car was running hot would cause water pump to leak?

 

prijedor, you seem fixated on the overheating issue for some reason... is there something you're not telling us?

Or are you hoping that one of us will say "Yes, the pressure release system in your $10.99 radiator cap has failed, causing your water pump to over-pressurize and spring a leak."

Sorry, bro. Not gonna happen. Blau is an excellent source for 99% of the bits and pieces we need to keep our vehicles running. But everybody who has replied to you message keeps saying the same thing. Their water pump is just not something you want to buy from them.

The reason? Their water pump's impeller (the spinny part that circulates the coolant) is made of a substance called PPS. PPS is short for Poly Pheneline Sulfide. You know what else it's short for? Plastic. I don't care how many people try to throw statistics at me, trying to tell me that this PPS stuff is closer to the original intent of the engineers who designed this system to begin with. Sure, PPS is much better than the original Durethan impeller that the engineers used. But why should I just blindly trust them at this point? These are the same engineers who designed my car with an automatic transmission that should have its fluid changed every 20,000 miles, but then sealed the damned thing and called it a "Lifetime" transmission that you should never touch yourself.

Do I really want to trust that kind of thinking? No, I don't. That's why my Cab's 12V V6 has a metal-impeller water pump from FCP Groton.

 

Ok, I'm getting scared here after reading this loudgoldwing as I just pulled my motor and its back in as of Sat. With a Blau timing water pump kit. I was shocked to see it wasn't a metal one. I then went and read Blauparts site because last spring I swear they said and bragged about it being a Metal propeller one!!! Now they switched their story about how good the PPS is one is and they have them made to high standards??? So its not even German made and now I'm scared after all my hard work and money. I would think and hope they don't leak and have problems?? As they built a good name for themselves for just timing belt kits. Meyle is a metal one because I seen it listed on German autoparts. Anyways, I hope I don't have no problems. I never heard nothing bad until this post. I'm not planning to tear it all down again anyways I thought I would write about my concerns since I just stripped down 2 AFC engines. Duane MI 95 90Q Sport
