Hello All,
I bought an '03 Lumina S (middle-east spec, you know; normally aspirated 3800 V6), and the previous owner had the coolant system flushed and the thermostat replaced. The car's been running fine, but I noticed the temperature gauge fluctuating quite drastically today. There are no leaks visible or any steam, etc.
I'm thinking this is a sign that the coolant system might have air in it--do you agree? If so, my browsing through this forum (I used ye olde "search forum" button--wonderful creation, that) would indicate that I should just open the air vent valve atop the coolant outlet to release any air, right?
When the radiator cap is off and the car is running, the water is circulating so I know it's not the water pump acting up. Since the thermostat was just replaced, I assume that's not the problem. Are there any other possible culprits for the temp doing this? Bad radiator cap, maybe?
Thanks!
