Vacuum Advances Back to Chevrolet Index
Vacuum Advances
Distributor vacuum advances have a delicate diaphram inside and if they leak will cause the engine to run erratic, idle rough, loose power and overheat. You can test them by sucking on the end of the vacuum line. If you can suck air, it’s replacement time. Some will require your old part in exchange.
