All too often when a new car comes to me, I recommend service based on the current recommended interval, but there are some items—timing belts come to mind—that don’t always display problems when visually inspected. We can’t really tell how many miles a t-belt has on it. Absent physical damage, if the customer doesn’t remember when it was done, you’re in the unfortunate position of being forced into recommending a service the car may not need.
Unless the previous tech wrote some mileage or slapped a sticker under the hood. Then you’re golden. I’ve gotten aggressive about doing this over the years. Here are a few things that live in my box and I guarantee at least a few live in yours:
- Felt tip marker
- Grease pencil
- Paint pen
- Metal marker
- Silver/gold paint marker
- Scribe
- Soapstone (Well, that’s over on the welding cart. But sometimes it works well in a pinch.)
