nequamminor Posted January 24, 2008 Report Share Posted January 24, 2008 I just did the water pump about 2 months ago, however the car has just recently started leaking coolant. It looks like the coolant is coming out of a little housing on the front of the engine. I remember taking the housing off when I first got the car because it looked like a thermostat housing. Its very possible I didn't put it back on tight enough, or the gasket went. There are two hoses going into it, and it bolts down to the engine with 2 bolts. It drips pretty quickly straight down on a wire by the A/C compressor when the car is up to temp. Does anyone know if this housing has a gasket, and if so what the name of it is or what the housing is called? Quote Link to comment Share on other sites More sharing options...
Robby1870 Posted January 24, 2008 Report Share Posted January 24, 2008 That's not the thermostat, its more of a distribution block and yes there is a gasket. It's called a Water Outlet Gasket. Quote Link to comment Share on other sites More sharing options...
ManicMechanic Posted January 24, 2008 Report Share Posted January 24, 2008 Sounds like the water outlet, yes it does have a gasket. Quote Link to comment Share on other sites More sharing options...

nequamminor Posted January 27, 2008 Author Report Share Posted January 27, 2008 I put a new gasket on the water outlet, and it leaks just as bad as it did before, if not worse. There is a puddle that is roughly 3 feet by 2 feet in size underneath my car that consists of coolant now. Could there be another issue that is causing this leaking? Or could this be solely due to not RTV'ing that gasket when I replaced it? Thanks again guys. Quote Link to comment Share on other sites More sharing options...
nequamminor Posted January 30, 2008 Author Report Share Posted January 30, 2008 Does anyone have any other thoughts as far as the leaking goes? Is there another gasket in the area that could leak coolant? Quote Link to comment Share on other sites More sharing options...
Robby1870 Posted January 30, 2008 Report Share Posted January 30, 2008 The water pump is right there, so that could be an issue, or even where the lower radiator hose attaches. Exactly where is it leaking out of? Visible (other than the puddle)? Quote Link to comment Share on other sites More sharing options...
nequamminor Posted January 30, 2008 Author Report Share Posted January 30, 2008 Hard to say exactly where it leaks out of, although it looks like it flows somewhat over the top part of the water outlet piece. I'm not sure about the hoses condition but I do know that when I originally went to replace the gasket, I couldnt get the hoses off for the life of me, and i tried to loosen them with a screwdriver figuring I'd have replaced them if they fell apart anyways. So they may have 195xxx miles on them. I've watched the car idle though and I never saw a spray, so I don't quite understand how the top of the water outlet could get wet and appear to have flowing coolant on it.

Robby1870 Posted January 30, 2008 Report Share Posted January 30, 2008 Sometimes when a pump goes bad, you will not be able to see it dripping, but it will. However, from my experience in those cases, the leak is not that severe. Is there a bleeder screw on top of the water outlet? I want to say there is something on top, maybe not a bleeder screw, but something. Maybe that is leaking? Can you take some pics and post them up?

Robby1870 Posted January 30, 2008 Report Share Posted January 30, 2008 I just looked at some pics of a 3.1L and the thing I'm thinking about sticks out of the side. I'm not sure how the LQ1 water outlet pipe routes, on the 3.1L it goes up after the water outlet. That pipe could have rusted through above the water outlet, just a little and coolant is trickling down? I'm kinda stumped so I'm just throwing ideas out.

nequamminor Posted January 30, 2008 Author Report Share Posted January 30, 2008 This first picture shows where the two hoses connect to the water outlet. The bolt that is visible in the picture is one of the areas I see coolant when I look at it while the engine is running. Its everywhere else as well, but I see it up there which is what makes me doubt the hoses a little bit. The second picture shows an upclose of it where you can still see a little coolant from at least 12 hours ago. It also shows what great condition my hoses are in. Keep in mind though that I did try to remove these hoses and may have beaten the hell out of them doing so, that's where that green stuff around the edges of them comes from. It was there when I got them to move back a little bit, and then pushed them forward as much as I could, but not where they were originally.

gp90se Posted February 1, 2008 Report Share Posted February 1, 2008 When you had the diverter piece off, did you happen to put it on a flat surface to check if it's warped or not? my camaro warped a t-stat housing, RTV'd it till I could get another one.

nequamminor Posted February 3, 2008 Author Report Share Posted February 3, 2008 Turns out that the cast aluminum piece in between the two hoses is cracked. It bolts into where the water pump housing is. Does anyone know the part number and/or name for this piece? I've looked at gmpartsdirect.com and I don't know where else to look.

nequamminor Posted February 5, 2008 Author Report Share Posted February 5, 2008 Item Number MSRP Price 10130907 $19.37 $11.48 INLET-WAT I went to two different dealerships today just to check for consistency or whatever, and I came up with this part number. Item Number MSRP Price 24503051 $55.68 $33.01 CATEGORY: Engine Coolant Pump Inlet I got the second part from the dealer, and they wanted 59.30 with tax. Could these parts be interchanged between the engines? That's a decent price increase for a part that may not be any different. Thanks for the previous help and any other input.

5speedz34 Posted February 5, 2008 Report Share Posted February 5, 2008 Well the dealer is going to charge like at least a 30% markup over list. Did you have them cross-reference the orginal number? Quote Link to comment Share on other sites More sharing options...
