It is always a struggle to remove a crankshaft pulley on a vehicle. The bolt is usually cemented in with thread-locking compound and tightened to over 100-ft./lbs. Specialty tool companies have introduced crankshaft pulley sockets designed to work with impacts. The difference with these sockets is the weight. The extra mass helps your impact to produce more force to remove the bolt. These sockets come in 17mm, 19mm, 21mm and other unique sizes. 2. INSPECT THE VEHICLE OR GET BURNED Inspection is the most critical first step that must be performed before the first bolt is removed from the timing belt cover. The inspection needs to include looking for the usual leaks and inspecting items like the oil, motor mounts and accessory drive belt components. You should also scan the vehicle for both active and historical codes. Codes for camshaft and crankshaft synchronization and issues with the variable valve timing system need to be diagnosed first. The inspection has two benefits. First, it spots any items that may limit the life of the new belt. Second, it allows for a more accurate estimate. It can also save you from a dispute with a customer who contends that the problem was not there before the timing belt was replaced.
