the intakes go bad on these engines....... they leak coolant in the cylinders and cause a hydro lock that causes the rods to bend making the piston skirt hit the crank......" clicking noise" theres a law suit in progress for this issue......... you can find info on the internet

That does happen ~ more often than you would think,unfortunately. The 2006 Cobalts seem to be falling to pieces right now,though. If you are still under warranty make them check and repair everything especially your computer.

SOURCE: a few seconds after brakes are applied the pedal

you have two problems here, your master cylinder has a leaking seal, the low pedal is resault, the power brake booster rubber diaphram is damaged and leaking from the brake fluid that is getting into it from the master cylinder, these are sold as a unit that has been rebuilt.

Testimonial: "Thank You for your response. However there is a new twist that I posted."

Why does my Pentair Booster LA01N sound as if it is spraying water internally ?

I think it's got air in it - that's what cavitation sounds like. Is the pickup gathering some air? Do you have an air bleeder near it someplace, or a valve you can use to bleed air out of it?

How to remove the impeller of pentair booster pump?

Remove the rear motor cover, you will need pliers and a 7/16 open end wrench. The opposite end of the impeller has a shaft that has to be secured by the wrench. The shaft has a notch on each side, it could be behind the two small springs that hold the spinning connection. There is a bigger shaft version that needs just a small end cap taken off and that will expose the shaft to be held and that is a bigger wrench. Once the shaft is secured, you may need pliers to turn off the impeller. Turn counter clockwise. Remember to be careful, it's plastic and well used. Don't forget the seals to put it back together.

Hi, My booster pump for my pool is very loud. It is a Pentair model number LA01n. It has gotten louder over a period of about 2-3 months. It has a small leak in the front seal and I had the seal...

YOUR BEST BET IS TO COMPARE MOTOR REPLACEMENT TO AN ENTIRE PUMP REPLACEMENT
MORE THAT LIKELY ITS PROBABLY NOT A GREAT INVESTMENT TO JUST DO A MOTOR ON A BOOSTER PUMP
YOUR MOTOR IS NOISE IS COMING FROM BEARINGS INSIDE THAT ARE GETTING WORSE AND WORSE
NOW A DAYS I STRONGLY DON'T RECOMMEND EVEN TRYING TO REPLACE JUST BEARINGS THEY NEVER LAST LONG AND ITS ALMOST AS COSTLY
HOPE THIS HELPS--CHARLIE -POOL PROS

I have a leak, just below the hose connection on the top of the pump. It appears that there is an adaptor/connector on the top of the pump, just underneath where the hose is connected. Just below this is...

I worked for Pentair for three years, the leak you describe is a common one. The adapter is removable from the pump housing. There is probably a bad O-Ring between these two parts, which is the #1 cause for leaking! If you have an Owner's Manual, refer to that, if not, here is the link online:

Pump is not drive enough water to move the sweeper

If the pump ran dry at all and if you had air it very well may have you could have burnt the impeller or it may just be clogged, Remove the 6 bolts holding it together and pull apart, using pliers or vice grips hold the shaft and unscrew the impeller if it looks ok run a curved wire through the veins of the impeller. This should help. If the impeller is clogged their is something getting past the filter and you will need to fix that. Also. don't forget to check your finger screen.
