Coolant leak on 5.7 vortec


Recommended Posts

Posted

Water pump was leaking on my suburban so swapped and now I’m noticing above the water pump and to the right directly under the ac compressor I’ll get some pictures in the morning but I do have a video of the leak. New to the site sorry if I posted in the wrong section. Need some ideas on what this is that’s leaking.. intake gasket maybe ?

Not sure of your year model and engine, but I have a ‘98 5700 Vortec in a C3500 and I had coolant leak from intake gaskets around 225,000 miles.  Expect corrosion on I take manifold surface as well. I was able to grind out corrosion, JB Weld, and then work it down with a file and then wet rock. Some folks wouldn’t suggest it but at 283,000 miles now and solid as a rock.
