Welcome to the club. I posted a few days ago about my Mez going out and yes, the temp gauge just shot to the red zone and I got a check gauge lites, on the dash about the same time time.
I pullrd the pump yesterday, and it was blowing fuses but it also had a good bit of resistance when I turned the impeller (at least from what I remember when it was new). Seems like it is binding.
Mine cooled very well from the onset until this happened. Mez told me they do have problems with the LT1 version. My question is ..what are they going to do about it?
On the other hand CSI seems to be doing a lot better off on the quality side.
MEZ's number is 1-800-208-1755. Their CS seems to be very good, but I don't want to check out how well someones CS is, I want a product to work as advertised.
I will be putting a warning lite system in sooner than expected since using the upgraded OPTI, HC ,and Cloyes setup dictates what my cooling options are.

 

YES I DO REALIZE MY CAPS ARE ON AND FOR A REASON. FOR THOSE 2 BUTT HEADS( WATCHING MY LANGUAGE) YOU KNOW WHAT YOU CAN DO!

DONT YOU EVER SAY ITS NOT A HONDA IM DRIVING. DAMN IM I PISSED. YOUR SATEMENT YOU MAKE IS SUCH IGNORANCE ITS TERRIBLE.

I WATCH MY GAUGES ALL THE TIME AND FOR YOU 2 TO SIT OVER THERE AND SAT ITS MY FAULT BECAUSE I DONT SIT THERE WITH MY FREAKIN 1 EYE ATTACHED TO THE GAUGES AND THE OTHER TO THE ROAD HAVE NO IDEA HOW TO OPERATE A VECHILE LET ALONE BREATHE. WILL I GET FLAMED FOR THIS---I DONT CARE. OF ALL 400+ POSTINGS NEVER HAD I EVER SAID ONE NEGATIVE THING OR TRIED TO FLAME ON ANYONE BUT YOU TWO ARE FOOLS. DONT SIT BACK THERE AND TELL ME YOU NEVER TAKE YOUR EYE OF THE GUAGES.

JUST FOR YOUR FYI THIS HAPPENED WITHOUT WARNING ON AN INTERSTATE AT 4:30 IN THE MORNING. I LOOKED DOWN TO NOTICE MY TEMP GAUGE HEADING TO THE RED. I PULLED OVER RIGHT AWAY AND THERE WAS NOTHING I COULD DO TO STOP IT FROM OVERHEATING. I EVEN TOOK A TOWEL AND BURNED MYSELF A FEW TIMES RELEASING THE PRESSURE FROM THE RADIATOR. IT COOKED IN THE MATTER OF MINUTES.

DAMN THE FIRST GUY THAT SAID THAT IS MY FAULT SURE HAS ME PISSED.

 

Maybe cause he is not driving a winston cup nascar. He shouldnt have to look at his gauges that often on his daily driver. If thats the case then maybe Meziure needs to put a disclosure saying "not our fault check gauges very frequently". When you drive an everyday driver yea you glance at your gauges but like he said there was no time to do anything it was too late. Tell me this, what would you have done to keep the head gasket from blowing after pulling over immediatly like was done by "Ucrazy"?

 

Ucrazymonkey,

Gotta agree with you about it being difficult to keep your eyes on the gauges. Whenever I am accelerating hard, I glance at my rpm gauge, but I don't stare at the temp and oil pressure.
I think next time, if you decide to get a CSI in the future(since Meziere is now out of the question) you should get Ryan to hook up a warning light for you. Ryan has one on his car, because he had initial problems with the Mezire as well. When he installs mine, I want him to hook up a warning light for both the CSI and my oil pressure.

 

Have you considered wiring a extra wire after the pump fuse and onto a LED light. This way you could at least know that your pump is getting power all the time. I will agree that most, waterpump failures are caused because of bad wiring. But watching your gauges on a non-stock vehicle is something everyone should be responsible for. When you modify a vehicle, you compromise driveability, realiability, in return for more power/faster times. It is part of the game.

I have no waterpump failures yet. Had it four months.

Good Luck

 

you guys a MORONS- and i say that with passion-
its his fault because he didn't watch his freaking guages?

I dont even know where to start with that statement

 

One guy I know bought two Meziere waterpumps. (accidentally) I bought one from him and after two weeks, it started leaking through the weephole. I took it off and sent it to Meziere. They fixed it and said it was a bad internal seal. I found out that the guy I bought this pump went through the same, only his died completely, just like yours. And it happened at the same time with mine. Maybe the problem of the new ones is an internal leak that sometimes escapes through the weephole and other times it just fries the electronics?

As far as watching the temp gauges, I would say that while you could prevent it, you shouldn't have to watch them all the time. (Well, I did, but I'm just simply paranoid)

I also built a switch and warning LEDs to show me when it's working and when it's not....

Call Meziere and ask to speak with Don. (Don Meziere = owner)
Last time I started a thread like this, he was very helpful.

 

As for the people watching gauges, do you have any idea how fast your temp guage rises when your wp is not working. You have no flow what so ever in the motor for cooling. When my first Mez crapped on me, I might have driven a whole 2 miles while driving easy and my temp guage was pegged.

BUT, when you get an electric WP, you are taking risks and you must assume responsibility for failure.

 

I bought one 3 years ago and it lasted about 4 months. Mine siezed up at the impeller.

Use the GM, it works!

 

Makes me glad that my dad had me go with an OEM. He said he wouldnt help me do an electric because he didnt want to have to mod the car to get it to fit. I dont know if the meizure is direct fit or not but Im glad he said that cause since he wasnt helping me I went oem so I could learn. THANK YOU DAD
It was a pain to do so I NEVER want to do it again

 

Well, you can't blame the pump for warping your heads. mine has stopped for various reasons over the last couple years, yet I have yet to hurt my motor.. just gotta pay attention to your gauges.

 

I do also watch my gauges constantly but like CANTONRACER said, when the waterpump goes the temp rises real fast, and without some kind of warning light it could mean a blown head gasket. They make warning lights so I'm sure that it could be done very easy. I just don't understand why anyone would run an electric water pump without one!!

And as far as the statement that was made by Chrisbequick, "You know an electric water pump is going to go sooner or later.", that makes no sense. If you read his post, you would have seen that the pump was basically brand new!! His exact words,"First one lasted 106,000 miles and the meziere pump= 2300 miles!" There is no reason that he should have been expecting this to happen. Clearly there was a defect or something with his pump.

I would think that these things would have some kind of warranty on them considering that they are part of a major function of the motor. Basically if it fails, you could be in big trouble.

 

Ya, I also recently replaced with a OEM pump. I gave the electric types much consideration. I figured this is my girfriends daily driver and electric pumps are probably more for racing applications. I think I made the right choice. I hope you guys having problems with these pumps get em straightened out. No matter what these companies do to take care of it, they arent going to pay for your labor ,which sucks!

 

Listen.. The mechanic i use is a certified Master GM Technican and has dome many Meziere Pumps on the side. In fact he has one on his car now. He has had it for 2 years and it has never gone out. Reading old posts it makes me wonder if Meziere has done something different in this last year. Alot of problems with the pump seems to have started in the last year.


I do watch my gauges. Infact I probably sneak a peak every 5 minutes. This was something I could not avoid.

What has made me mad is the fact that a couple of folks have said it was do to my foolishness of not staring at my gauges 24/7.

The day I put this pump on was the day I had to watch my gauges. I understand that this pumps harder than the stock pump and if I had a problem with my radiator it would show. the problem is that this pump does nopt work in my car. and judging to the responces nor does it work in other folk's cars.

 

I'm going to add a "fail" LED based off this circuit :

I won't be rigging the "faulty ground" LED though.

You guys have me all nervous about my pump now.
