right now I'm in the process of changing my water pump for a 1999 Chevy lumina saden. I'll change it out monday April 24th,2006 and get back with you. i have been to different sites and they don't help. i will tell everybody this. they are two water pumps and make sure you have to right one. my engine is a 3.1 v6 and i believe it has a housing. I'll know more since i have to work the next two days. also the water pump is located on the or near the top on the passenger side with the radidator hose and another hose connected.like i said before I'll replace it and get back with you all and tell you how i replaced it.

I TOLD YOU THAT I'LL ANSWER THE QUESTION ON MONDAY. HERE IT IS.THERE IS NO WEBSITE THAT I FOUND TO DO THIS. THE TOOLS NEEDED ARE AN 8mm and 10mm SOCKETS OR WRENCH. YOU NEED A 3/4 RACHET. FIRST YOU FIND THE TENSIONS PULLEY AND PUT THE RACHET IN THE SLOT TO LOOSEN THE BELT.IF IT DOES NOT DO THIS THEN YOU HAVE TO REPLACE THIS AS WELL. SECOND YU FIND THE 8MM SOCKET AND REMOVE THE BELT DIAGRAM. NOW TAKE THE 10MM SOCKET AND REMOVE THE 4 BOLTS HOLDING THE BELT PULLEY. MINE WAS EASY AND FORGOT TO TELL YOU THAT THE WATER PUMP IS IN A HOUSING SITTING ON THE TOP WITH THE HOSE CONNECTED TO IT. NOW YOU GET THE 8MM SOCKET AND REMOVE THE 5 BOLTS HOLD THE PUMP IN PLACE. AFTER YOU DO THIS IT WILL GET MESSY WHEN YOU PULL THE PUMP OFF. MAKE SURE YOU CLEAN THE OLD GASKET OFF THE AREA AND NOW YOU ARE READY TO PUT A NEW PUMP BACK ON. WHEN YOU DO THIS MAKE SURE THAT THE SILVER PLUG IS ON THE BOTTOM AND THE GASKET HAS A EXTENDED PART THAT GOES ON THE TOP.REPLACE THE 5 BOLTS AND THEN THE 4 WITH THE BELT PULLEY.YOU MIGHT NEED TO REPLACE THE BELT OR YOU CAN STILL USE THE OLD ONE.MAKE SURE THE BELT IS RUNNING OR PUT IN THE RIGHT GROOVES THEN PUT YOUR RACHET BACK INTO THE TENSION PULLEY AND TIGHTEN THE BELT. AND ANITFREEZE AND START YOUR CAR. KEEP ADDING THE ANTIFREEZE TIL IT IS TOPPED OFF. NOW YOU ARE READY TO DRIVE.I KNOW I AM NOT A CERTIFIED AUTO MECHANIC BUT I HAD TO REPLACE MY OWN WATER PUMP TWICE AND THAT IS HOW I DONE IT. THE FIRST TIME MY TENSION PULLEY TIGHTEN UP OR WAS BROKEN AND RUINED THE PUMP AND BELT. LUCKLY THE PUMP WAS UNDER WARRANTY.

THANKS GDS1958

Hopefully you mean a 1992 Lumina, and yes, most starters are standard.

Remove the tire and wheel from your 1999 Chevy Lumina. Remove the nut on the top of the ball joint. Pound the ball joint out with a hammer. Reverse the process to install the new ball joint.
