echosierra3 Posted March 11, 2011 Report Share Posted March 11, 2011 I have been noticing a few drops of coolant on my garage floor, so today I investigated the source. There is a small 3" long straight hose with 2 clamps, that comes off the right side of the water pump,(as viewed from the side of the car)and heads back to the firewall. Maybe to the heater? Anyway, that seems to be the source of the leak. Does replacing that hose require removal of the pump, or can I cut it in two and remove and slide in a new one?

KHE Posted March 11, 2011 Report Share Posted March 11, 2011 Is it a green, silicone hose? If so, you should not need to remove the water pump to replace that hose. Maybe the clamps just need to be tightened? Kevin '93 Fleetwood Brougham '05 Deville '04 Deville 2013 Silverado Z71 Link to comment Share on other sites More sharing options...
heitzman Posted March 11, 2011 Report Share Posted March 11, 2011 Mine was replaced with the water pump in place. You might check all your hose clamps while you are under the hood. Link to comment Share on other sites More sharing options...
echosierra3 Posted March 12, 2011 Author Report Share Posted March 12, 2011 It's not a green hose, standard rubber type, the clamps are the squeeze and release oem type, so I can't tighten. Link to comment Share on other sites More sharing options...
heitzman Posted March 12, 2011 Report Share Posted March 12, 2011 I believe if it is green it has been replaced. I would replace all of the OEM clamps with a good quality hose clamp. Link to comment Share on other sites More sharing options...
Ranger Posted March 12, 2011 Report Share Posted March 12, 2011 There is a green silicone hose from the factory. It's under the TB I believe and silicone was used because of the heat it is exposed to and the difficulty of replacement. Link to comment Share on other sites More sharing options...
hcpcl Posted April 16, 2011 Report Share Posted April 16, 2011 this might be to late but i thought it was just 1 hose but there is a tube connected to this hose thats stays on. i went to the junk yard got 1 for ten bucks easy fix. i had the same problem two drops of coolant, but my hose was about to burst, i was lucky i found it coming out Link to comment Share on other sites More sharing options...
