Try replacing your fuel pump relay, Its common on chevys.Those fuel pumps are too expensive to keep replacing

Hello,
After your exhaustive tasks I feel one of two things are left to rule out.
First, have you an air lock? did you bleed the cooling system after installation of parts? if not try parking on level ground, with engine cold not running remove coolant filler cap and top up if required to correct level.
Start the vehicle and leave to idle with cap off, have plenty of hot water available, when at operating temperature you may here gurgling and see bubbles in the cooling system Beware not to get too close as it will hopefully boil over, after it does top up with warm water and wait, keep blower on full and heat to max inside vehicle.
It may boil/bubble over a few times before settling if so top up and replace cap once settled.
Finally if an abundant amount of air bubbles are continually visible and regular bubbling over then unfortunately the cylinder head or gasket could be at fault.
I hope this points you in the correct area.
Please remember to politely rate this possible remedy!

After replacing the thermostat, you must bleed the air from the cooling system.

To bleed air from the 2.2L and 2.5L engines, remove the plug or sensor on the top of the thermostat housing. Fill the radiator with coolant until the coolant comes out the hole. Since the plug is made out of steel and the thermostat housing is aluminum, it is a good idea to apply an anti-seizing compound or Teflon® tape on the plug threads prior to installation. Install the plug and continue to fill the radiator. This will vent all trapped air from the engine.

Any trapped air in the heating system will have to be displaced by coolant. Once the cooling system is filled, with the radiator cap off, turn of the heater at it's highest setting. Start the engine and allow it to reach operating temp. You should see a drop in the coolant level as the air in the heating system is displaced by coolant. Add coolant to the proper level and replace the radiator cap.

Keep a close eye on the coolant level for at least the next couple of weeks. The cooling system is a "closed" system. Any significant decrease in coolant level indicates a problem.

If you have any questions, let me know.

Please take the time to rate this solution.

Drive safe and be warm.

SOURCE: Water pump on 2005 Chevy Equinox

Water pump is locate on the front center of the engine.

I will rate water pump change as a 7/10 in difficulty scale.

You should check for special tool(s) requirement from the library before you start.

It's a good time to change the drive belt at the same time.

50/50 coolant mix is fine.

If you haul heavy load or in cold climate then bump it up to 60/40 mix

DO NOT FORGET to find or draw the belt routing diagram before you undo the tension.

A 30 second sketch will save you a lot of time.

95 Chevy caprice leaking antifreeze from what looks like a pipe under the engine.. But the serpentine belt is wet & spraying antifreeze, so wherever it's leaking from, it's hitting the serpentine belt


Your water pump has a small hole on the top and the bottom of the housing right behind the belt pulley. This is known as a weep hole and is there to let you know when the front seal has gone out of the pump and it is in need of changing. You really want to get this taken care of because on your engine the ignition system is ran off of the crank pulley and is known as "Opti-Spark" when the system gets antifreeze in it it usually goes bad. The Opti-Spark distributor sits right underneath the water pump, so a leaking water pump soon will take out your distributor which is another added expense.

Think the oil pressure switch keeps the fuel pump running once started. Suggest replacing Oil pressure switch. And no it won't effect oil pressure reading when it goes bad. The switch is a safety device. When you roll it over and the oil pressure drops the switch cuts off the fuel pump. Neat huh? Need some good feedback Thanks!

My 93 chevy caprice has new water pump and themostat but temp gauge still indicates its still running hot.


Could possibly have a clogged radiator, Which engine does your caprice have? You also need to make sure all air is purged from the system.

When does it over heat, all the time, or just when idling?

92 chevy caprice water pump pics


You can get like a chilton book for the car at autozone for around 20 bucks.This is a rear wheel drive car and the water pump is easy to get to. Remove the belts and remove the fan and where what the fan bolts to is the water pump. remove the hoses and a half dozen bolts and pry it off. And the best part is the water pump at autozone with a lifetime warranty is 30 bucks.

Heater core is plugged or you have a air pocket. If you take off the heater lines and try blowing through them both ways. The fans will not move until the engine gets hot.

99 grand am gt overheating changed thermostat and


try priming the engine block & radiator with water though the hose's & any hose you can squeeze to pump out the air lock with the filler cap off when running, sounds too much air is is in the system & the pump won't work dry.
I had this problem a few times & I ended up practically forcing water into any hose I could re-attach quickly using a garden hose, as the heating system need's priming too !

How do i locate and change a water pump in a 1995 chevy caprice?


Well the water pump will be mounted directly to the engine block with two large hoses running from it to your radiator.

When you get the new water pump make sure it has new gaskets in there. Should only be a couple of bolts and it comes right off.

Scrape off all of the old gasket from the engine block before you put the new gasket and pump on.

Good luck!

-Captain Jake

PS - Might have to drain your radiator first, it has a little valve at the bottom. And PLEASE make sure the car is cold so your poor husband doesn't burn the **** out himself :D
