Re: 98 lumina,coolant leak on floor.=
If a coolant pressure test doesn't show the source, than add coolant dye and use a black light...
I am guessing a 3.4, and lower intakes are famous for leaking... |

It's possible that the TC cover is leaking. It's more probable that the corner of the intake or water pump would be a source.

Re: 98 lumina,coolant leak on floor.=
my back yard mechanic replaced the water pump about 10 days(?) ago.. it had a residue around the seep hole so we figured that was it.
the manifold gasket was replaced years ago with a metal felpro. car has about 280,000 miles on it now. curious thing= I,ve been having vacuum problems for a while. wonder if there,s a connection to this coolant leak somehow? |
