in 2000 i installed the helitool ps pump on my 230. i drained the coolant at the time and then installed bracket and bolts with silicone sealant. waited for it to dry and then refilled. i haven't used truck much since i started the restore in 1996. maybe 100 miles of test driving. i saw bubbling around one of the installed bolt heads. i dropped coolant again and removed the offending bolt. it was loose (i tested it before pulling). even though i dropped the coolant, i heard a sucking sound when i removed the bolt. i cleaned out the hole with some solvent on a fabric strip until clean. i reinstalled bolt with more sealant and have let it sit overnight. any concern about the air sound? what could have caused it? dont want to start and run the engine if i have missed something. thanks!
