Glow Plug Service

In our experience, diesel glow plugs begin to fail in the 50-80,000 mile range. The design of the cylinder head on the twin-cam diesel engines requires that the glow plugs be threaded through long, narrow bores leading to the center of the combustion chambers. Unfortunately, one or more of the glow plugs will likely be seized in its bore by the time it fails. The only way to remove seized glow plugs is to remove the entire cylinder head and then drill them out using a special fixture, and install steel threaded inserts in the head.

Our alternative is to Remove the glow plugs before 50,000 miles, clean their bores with the Mercedes-Benz reamer tool, and reinstall them with anti-seize lubricant. The job can be completed in less than 2 hours and will save you thousands down the road if you expect to keep your Sprinter for the long haul.

Pre-Purchase Inspections

If you're considering the purchase of a pre-owned Sprinter, a pre-purchase inspection is a wise expenditure. We can give you a clear picture of the vehicle's overall condition and point out specific issues that will need to be addressed. The two most obvious benefits to you are:

  1. We can protect you from purchasing a misrepresented vehicle with hidden problems and / or requiring expensive repairs.
  2. We provide you with knowledge that will help you negotiate a sensible price with the seller.

We will perform a complete diagnostic scan, road test, and visually inspect the vehicle for about one hour, and consult with you for another 30 minutes to discuss our findings.

Beyond the basic inspection described above, we can investigate specific items in greater detail if needed. Such services will be billed to you on an actual-time basis at an hourly rate of $90.00.
