What engine 3800 or 3400
3800 has i think 8 or so bolts
3400 has 5 bolts
make sure all the bolts are removed if so use a screwdriver and tap it with a hammer against the water pump flange
hope this helps

How to install water pump

Drain the cooling system.
Remove air cleaner.
Remove water pump belt cover (4 bolts)
Remove water pump drive belt by moving the belt tensioner in the direction which loosens the belt.
Remove the bypass hose
Remove the lower hose and pump cover.
Use remover/installer tool (J-38816), rotate pump assembly clockwise to remove from vehicle.
** this tool may be available for "rent" from your local auto parts store. It is necessary to prevent tearing the new pumps' seal during installation and it make removing a stuck pump much easier. Also, once you return the tool the auto parts store refunds ALL of your money.

Could be a faulty water pump, clogged or stuck Thermostat or clogged radiator. Once the engine cools down remove the radiator cap then start the engine and wait for it to warm up to operating temperature. At operating temp you should be able to see the fluid in the radiator circulate. If you don't then you need to let the engine cool again and remove the thermostat or replace it. And run the same test again. If you still don't see the fluid circulate then replace the water pump.

Check your impeller in the seawater pump ( at the front of the engine )
If the impeller blades stays even lightly bent after removal, change the impeller.
Check for obstructions in the hoses.

Run the engine, if here you have a good water flow ( more than at the exhaust itself ) the the exhaust mixer is obstructed. Try to clean out with HCl acid. USE ACID resistand GLOVES. Rince twice as well after the obstruction is gone...

Coolant does not seem to be circulating in radiator(94 z28 camaro). The radiator is brand new and it seems not to flow even without the thermastat on. I hate to think it is the water pump again, since the...

Remove the thermostat and run the car. Without the thermostat you should see FULL flow thru the radiator. You can pull the top radiator hose WHERE IT ATTACHES TO THE RADIATOR and start the engine with a garden hose stuck in the filler opening. Don't turn the hose on so hard that it blows water out the radiator hose. You want to water pump to shoot water out the disconnected hose, not the garden hose. A hose COULD be blocked, but it would have to be a pretty big blockage to cut off all flow. Not likely in my opinion. You could take them off and look in them and the heater hoses too. You can blow compressed air thru the heater core to see if it is blocked. As for it being the water pump...they rarely break so bad they won't pump water. Usually the seal goes bad and they leak water out the shaft. Look around, I kinda think you have a bad thermostat. Stuck closed. Drop it in boiling water and see if it opens. You didn't say what engine is in the Camaro, but most of them have a small bypass hose on the top of the water pump running to the intake manifold. Pull it off and see if water sprays out when the engine is running.

How common is a stuck thermostat or overheating.

A stuck thermostat is fairly common (especially if it's original on your truck). If the thermostat is stuck, its common for antifreeze to back up into the reservoir tank. I

A bad water pump will normally overheat at lower speeds. If you notice the engine temp comes down when you turn on the heater, it's most likely the water pump.
Best of luck.
