Thread: Coolant Loss
03-14-2012, 02:55 PM #1
Hi all, I need a little advice regarding coolant loss.
Recently my truck seems to losing/leaking coolant. Hoses and radiator seem to be fine, coolant appears to be dripping from under the engine.
I have enclosed a pic, showing (excuse my ignorance here please) the hole where the fluid appears to be dripping from. Should this hole have a plug? Should coolant even be in there?
Truck is a 95 Silverado 5.7l
Any advice would be much appreciated, thanks.Chevy Silverado 1500 ext cab

that hole should have a plug in theory but from the pic it hard to tell where that is. also if it seems your having coolant problems and the truck is running hot alot of the time your tempture control valve my be failing mine failed on my tahoe last summer leaked out all the coolant luckly it blew while in a parking look so the truck didnt over heat.

Can you take the same picture but zoom out a lil bit. It'd give us an idea what we're looking at.

Thanks for replying guys, have managed to get a more zoomed out pic. The top of the pic is towards the front of the truck and the oil filter is visible in this one. The hole is in the middle of the part at the top, with 3 green blobs of coolant around it. (looks like I may have a little oil leaking on the part next to the filter too? :s)

While Conlan is looking, you may want to give this one a shot as well. You'll probably end up with the same result as the Haynes, but may be worth a try.
You'll find the manual's link on post #61. For some reason if you just save the link it eventually locks you out, but if you click from the thread you should get in every time.

thanks for that advice, will look into the Chilton site.
Got to log out now, anniversary dinner, .... apparently more important than my truck in the eyes of the missus.
