1995 Lumina 220k on car about 90k on 3.1L engine
This car is running too hot. The temperature gage climbs at or near the red line and then a few minutes later comes back down. When the temperature is coming down, the gage can come down so quickly the needle bounces.
It does this under load and at speed but not so much when it is idle.
The following tests have been run:
--Coolant has been checked for chamber gases twice with none being detected.
--The water pump has been checked.
--System pressure has been checked
The following have been done'
--Replaced the radiator
--Replaced the thermostat twice
From reading the forum it sounds like the problem might be with the intake manifold gasket. What do ya'll think? Is this a difficult repair?
