Overheating
My 2005 buick rendezvous was over heating,
and was talked into putting in stop leak. Still
overheated. Then found out the water pump
was badly leaking so that was replaced. Still
overheating.
Changed the radiator hoses, same thing.
Changed the thermostat twice, still
overheating.
Did a flush and fill, with proper 50/50 mix,
absolutely NO leaking but still it's
overheating.
The oil looks just fine ... I don't really have to
add coolant unless I overheat to the point
where my Hot Coolant light comes on and I
blow fluid out the overflow reservoir .
Any ideas on what I can check or do next ??
