I’ve searched the internet high and low on this issue. 2011 Silverado 5.3 lc9. Recently replaced intake gasket, valve cover gaskets, oil pan gasket, oil cooler block gasket, pickup tube oring. The pan gasket was bad and that fixed my oil leak. I relize none of that has anything to do with the coolant leak. Now I have a leak that’s like an orange mud color on the passenger side by the motor mount. Which I’ve recently found out to be the motor mount. They are filled with a glycol hydraulic oil. I keep a stainless pan under the truck when I’m not driving it so it don’t leak on my driveway. My truck has been sitting since last Thursday in the driveway and the leak from the motor mount is present on the pan. However besides that I have a very small coolant leak. It drips down from above the starter and leaks onto the starter bolt. It had about four drops of coolant on that pan today followed by a small trail from the starter down the side of the oil pan. Upon inspection there is no visible leaks from the head area or the freeze plug in the back of the head. Nor do the coolant lines that go into the firewall seem to have any leaking. My truck hasn’t been drove in almost a week or started. There was nothing on that pan yesterday. I’m completely stumped and trying to get these leaks fixed. The motor mounts I can’t believe are still leaking. The passenger one has been leaking for a year and still leaking. Not really concerned with that due to the cost of replacement poly motor mounts. Any help is appreciated. Thank you.

Fluid film try it. It's an amazing product

I had a 2000 sierra once. When I traded it in they said the truck was great, except for the rusted frame. The cab corners and rockers on that truck were gone as well. My current truck is a 2006 sierra z71. It currently has 158,000 on it. With no rust on it period. When I purchased the truck two years ago, I sprayed the inside of the cab corners, rocker panels, wheel wells, and doors with a spray lubricant called fluid film. Fluid film is a rust prevention/corrosion protection. You can also buy a hose attachment for it to be able to reach those hard to reach places. Lot of people use it for under coating on their frame to help prevent rust or corrosion. If you live a state where they use salt on the roads like I do, I suggest using this product a couple times a year. If will definitely help. Also it can't be washed off, and it doesn't harm paint. The rhino liner or under coating gm sprays on their vehicles frames is just junk. You can scratch it right off. Also like the last person said. If you live in a salt belt wash at least twice a week. Fluid film is carried at a lot of different places. Autozone, car quest and tractor places. In bulk or spray cans. Fluidfilm.com Also maybe buy a ford! Lol
