I have a 1994 Bonneville with only 53,000 miles. It is losing coolant and no one cane seem to find out where it is going. It'* not on the ground or in the oil and a thorough inspection seems to to show no signs of leaking. Anyone have any thoughts?

Overflow tank? Is it full to the top?

by the way - please post your car'* model (se, sse, ssei) and year in you signature.

The tank is where I notice the coolant missing from. Also the car does not seem to run hot.

The car is a 1994 Bonneville LE

no such thing.. lets assume its an SE

You're correct it is an SE pardon my mistake. [/b]

i say intake manifold gaskets.

Wouldn't that show up as coolant in the oil and make the oil milky looking? If so the oil looks fine.

About how much does it seem your losing roughly.

Have you had an oil analysis completed?
