Coolant leak

Asked by Christopher Nov 25, 2018 at 07:09 PM about the 1998 Buick LeSabre Custom Sedan FWD

Question type: Maintenance & Repair

I’ve replaced the intake manifold, thermostat seals
and thermostat, radiator hoses, and also the
throttle body seal. But I’m still leaking from the
drivers side. It also had burn marks on the throttle
body seal connected to the manifold. What could
cause it?it only has 110k on it.
