Coolant leak

[phil_long]

I think it's coming from the water pump, but too bummed to even look at it. Am I asking too much for my car to just operate normally? I barely drive the damn thing. Im almost sure the guy did the water pump when he did the timing chain.  Hasn't been three years yet.

I guess you are going to have to look and see if it is coming out of the weep hole, around the long bolt that goes into the water jacket, or around the gaskets between the pump and block, and/or the hose.

Driving the car seldom does not help

Phil...hang in there. This stupid Impala SS gave me fits...so I parked it awhile. I got it sorted out...and it's running like a top. Changing the water pump ain't that tough. Get stuck...and the guys will be here to talk you through it.

I agree with Steve. Let the car sit...and seals etc dry out.

You have to remove the water pump to do the timing chain.

Odds are it's weeping out of one of the long bolts.   If that's the case the fix would be pretty easy as long as the bolt threads aren't rusted all to hell...

...or just drop in a GM seal tab.

I plan to do my own work from here on out. I hope to get chance to check it this weekend. I need to get under the car to see exactly where it's coming from, correct? And by not driving often, i mean every two weeks. Weekends depending on the weather.

If you start it and the under the water pump hole pisses water you found the leak. If it comes from elsewhere that is a discovery you will have to make. Just remember that the pulley and belt are moving when the engine is running. No loose clothing, or you could regret it.

If it's the weep hole on the water pump, there should be a visable stain where the coolant sediment stained the casting.  When one of my old rusty long bolts leaked there was a green ring where the bolt head met the waterpump and a nice little green droplet hanging down.

I checked everything around the water pump, and it seems fine. I then discovered that the leak was above it. As soon as I began to loosen(not even one turn) coolant started coming out of that hose right where the clamp is. After making a mess of inspecting the hose and tightening it back, I decided to wash the coolant off of the spot were it had been. I'll have to wait until its completely dry before we know for sure.

Needless to say, after giving the car a jump and getting it started, I heard something worse than the leak of coolant. I'm almost positive that the sound I'm getting from the motor is internal. My stomach hurts worse now. I'll video the sound after I eat. The car seems to run fine, but this knock sound isn't good.

So the S-hose leaked...   and now you have lifter rattle?

[Scoobum]

Earl's prolly right. Make sure it has oil pressure. Sitting too long...you may have to reprime it. Seen this situation more than once.

Sorry for the delay. Just back from a cruise. It was fun

check your flex plate bolts and your intercooler bolts.


Oh, and get some zipties or safety wire on those boost hoses running from the MBC

does the sound go away when you rev the engine a bit?  If so, I would guess cracked flex plate...cracke d between the mounting bolt holes...
