Tech Tip: Special Timing Chain and Belt Tools

Before you replace a timing belt, chain or gear set on some engines, you will have to look up the timing reference marks. Some engines have multiple timing marks that can cause confusion if you don't know which ones to use or how to line them up. Many engines also require special tools when changing a timing belt or chain. At the very least, you should have a belt tension gauge to make sure the tension on a timing belt is correct.

Many engines also require special tools when changing a timing belt or chain. At the very least, you should have a belt tension gauge to make sure the tension on a timing belt is correct.

You have probably seen many more businesses and retailers asking for tips during checkout. It is the screen typically seen before you approve the charge. I started to think about what would happen if shops would try asking for tips when customers picked up their vehicle. 

Asking for tips would probably not have gone over too well with customers in the past or in today’s constantly shifting tipping culture. I think it is a question of how people think technicians are compensated. If you are paying 20% gratuity on a meal, it is understandable. But, technicians and shops provide more than a service, they provide expertise and tools that should be compensated through the number of hours billed, not a tip from the customer.
