Ok, first symptoms....intermittent squeaking when cold and an occasional constant squeak while driving. I looked at it today and it appears I have coolant on the front leaf spring and on the balancer...nothing under the car..the reservoir is low...so I am guessing the pump is going bad. I thought these pumps leaked thru a weep hole on the bottom when they go out..is that what I am seeing even though I have nothing under the car??

Anyway..how long to remove and replace?


Thanks

Not sure on the time, but here is the shop manual steps:

Water Pump Replacement
Removal Procedure





Caution
Before servicing any electrical component, the ignition key must be in the OFF or LOCK position and all electrical loads must be OFF, unless instructed otherwise in these procedures. If a tool or equipment could easily come in contact with a live exposed electrical terminal, also disconnect the negative battery cable. Failure to follow these precautions may cause personal injury and/or damage to the vehicle or its components.


Disconnect the negative battery cable.
Disconnect the intake air tempeture (IAT) sensor connector.
Disconnect the mass air flow (MAF) sensor connector.



Remove the air intake duct/cleaner assembly.
Remove the accessory drive belt. Refer to Drive Belt Replacement in Engine Mechanical.
Drain the cooling system. Refer to Draining and Filling Cooling System .



Remove the radiator inlet and outlet hose clamps from the water pump.
Remove the radiator inlet and outlet hoses from the water pump.

Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.


Install the water pump bolts into the engine block. Tighten
Tighten the water pump bolts to (first pass) 15 N·m (11 lb ft).

Water pump is pretty easy. I have a stocker that i took off for an electric waterpump if you're interested...

Hardest part is scraping that damn gasket off the block! What a PITA

pewter99

Gee thanks Bill

I knew that BTW

pewter99

it will be ok..BTW I ordered it earlier...forgot to tell you

Only an issue on the older C5's.

The later years used MLS water pump gaskets which remove cleanly with nothing to scrape. Not sure what year they started, but my 01 had them.

If this is for YV's car, it shouldn't be an issue.

Thanks for buying it

pewter99

'VETTE PHASE

I know that you have already bought yours, but here's and FYI for anyone reading this that is getting ready to do the same thing. If you plan on getting a different thermostat, get a water pump for an '04 vette (same as an LS2). This water pump uses a standard thermostat that you can buy for $5-$10, instead of the one piece thermostat/waterneck that costs $50-$60.

Any problems or drawbacks to installing an '04 and up water pump on a '01 LS1? Any reason to stay with the pre '04 pump?
