Chevy Impala 2004. Need guidance on replacement of water pump on 2004 impala with 3.4 six.
Answer: To remove the water pump, first, make sure engine is cool and no pressure in the system, remove the belt. Then hold the pump pulley tightly and remove the 4 10mm bolts that hold on the pulley. Tap the pulley to remove. Then remove the 5 5/16 (or 8mm) bolts that hold the pump. Be sure a drain pan is under the car to catch the coolant. Clean the mounting surface of old gaskets. Install new pump, pulley, belt, and bleed the system
2006 Chevy Impala 3.5 Engine Has No Heat Had to add coolant. Especially when sitting at an idle. I checked the antifreeze, and it was low. I dont see any leaks on the ground. I had a pressure check done, but they did not find anything. Can you help, it is quite cold by me this time of year
Buick Lesabre 3800 V6 Coolant Leak Won't crank to start. One day it started riding funny so i pulled over and turned the car off when i lifted up the hood it was no water in it and there was no sign of leakage. I put Dexcool in it, but then it wouldn't crank
10-7-10 To tell or explain something is fine, but sometimes you could really use pictures or diagrams to make clear the explanations and show pesky bolt locations and such. Big Joe in Ohio
12-15-10 over heating while driving no more than a mile. Replaced Thermostat, radiator and serpentine belt. No leaks, pressure checked ok. No smells and oil doesn't look milky or yellowish on dipstick. Heater won't work but cool air will. Help....2004 chevy impala 3.4
No heat means either air in the cooling system- possible head gasket problem, or no flow. Check coolant flows through radiator when t-stat opens. Have seen impeller broke of water pump, and belt put on pump incorrectly.
12-16-10 also check the heater core may have stopped working.
4-15-11 Reference-12-15-10 I had same problem it was the head gaskets.
7-8-11 ok looking for some help here on the 3.8 l v6 there is an l shaped (looks like PCV valve) that looks as if it is coming out of the block and going into my tensioner. I need to know what that is and if it could be leaking coolant?
That is a coolant bypass pipe. They do break and leak coolant. You will have to remove the tensioner to get that pipe out. The other plastic pipe will probably break off during removal, so replace them both.
2005 Chevy Impala. Question: I put the wrong coolant in my car. I didn't realize it until I smelled something burning. So I took it to a mechanic they started talking amongst their selves,then the guy told me it was my water pump and thermostat. They even looked in and seen the green stuff I put in my car and said nothing about that. So I took my car to Oriley too get the water pump and thermostat they ask for. As I was talking to employee he said I put the wrong coolant in my car. What should I do?
Answer: First you have to fix the coolant leak. Get those parts replaced. While they are doing that, have them do a good system flush do get all the coolant out of the system. Best to have the plugs pulled from the block, as just draining from the radiator or from the water pump replacement will only get not even half of all the coolant out.
