Cap That Coolant Loss!

[Jazzy]

I suddenly started losing coolant last week, and solved it by just replacing the cap on the coolant tank. Had never considered that until a mechanic pointed the bad cap out to me. He said a bad cap could cause coolant loss as hot coolant boils away with a bad cap. My 21 year old cap had a crack on the side and no sealer gasket left inside it. $8 for a new Dorman cap and the problem was gone. (I had replaced the LIM gasket and manifold a couple years ago and had never lost any coolant since, until this cap episode last week.)

I had posted the above in an old thread dealing with coolant loss, and was hollered at for posting to a nine-year old thread. But it was a nine-day old thread to me, searching topics when I had a new problem. Newer owners of Bonnevilles have new-to-them problems all the time, and this forum has an amazing amount of knowledge and solutions accumulated over the years. Folks that have been here for many years may be tired of hearing the same questions and problems that they dealt with many years ago, but don't take that out on newer members. I'm just trying to help someone else out who may have the same Bonneville problem as me.
