Changed water pump in 2001 Chevy Blazer now water is pouring out from underneath the alternater bracket HELP

Your probably looking at a rebuild. Shops don't just fix the problem. They have to cover their rears.

seeing as you just changed the pump, can you hear the pump cycle when you first turn the key on? if not check all your plug in wire connections one my not have been in properly and came loose, hope this helps

my 98 Blazer I had to replace radiator water pump heatercore and hoses. Had head gasket go. Once that happens air and dexcool corrode cooling system. Do you smell antifreeze? Are you loosing antifreeze? Check oil see if its another color not clear or black but i think light brown. Have you flushed out system?

you have an electrical problem . check fuel circuit fuses, relays and sensors

If the system fills via an expansion tank, I would recommend removing the top hose from the radiator and filling the system by pouring the coolant in through the hose until it begins to flow out of the upper radiator port. Reconnect the hose and then fill the expansion tank. That should take care of it.

It sounds to me that your control module is bad It is located on the left side facing the engine on top of the intake

i never herd of this but you may have a hole in a water jacket you need to have it checked by a mechanic in your area.

You'll need to see if your fuel pump is providing fuel pressure. First test would be to take off fuel cap, listen through filler tube as someone turns ignition on for a few seconds, then off for a few seconds. Repeat a few times you should hear the fuel pump start then stop as it builds pressure.

No noise, then test voltage coming to pump if yes, 12 volts, replace fuel pump. Test ground also before replacing pump.

I would expect it to be this as the computer wouldn't allow the vehicle to run with fuel being poured into the engine otherwise.

If it's pumping, you will need to do pressure testing to determine if it pumps enough, or just replace it as either just the pump, or the complete pump assembly that drops into the tank rather easily.

Pumps are available at dealers OEM, discount auto parts stores, and I've had good luck with pumps that I've bought on eBay.



good luck

replace the fuel pump electrical wire harness.

it is not to hard to change the pump but you will need a fan clutch tool. the water pump is on the front of the motor with the fan attached to it.
