Do you diagnose before quoting?

Yes. We pull codes and inspect the truck first, then tell you what it needs and what it costs before any work starts.

Do you work on all engine makes?

We work on the heavy diesel engines that come through a Class 8 shop. Call with your engine and complaint and we will tell you straight whether it is a job for our bays.

Diesel Engine Repair Long Grove IL | Semi Truck Engine Shop

Diesel engine repair in Long Grove, IL

Engine trouble on a Class 8 tractor costs money every hour the truck sits. We put the truck on the floor, read the codes, and track the fault to the part that actually failed before anything gets replaced.

Why bring it to Truck Shark

We are a shop-based diesel repair facility at 7101 IL Rt 83, Long Grove, IL 60060, right on Route 83 and a few minutes from I-94. Tractor, trailer and reefer work happens in the same bays, so one visit can cover the whole rig instead of two stops at two shops.
