Higher than expected temperatures will allow the low pressure natural gas regulator gasket to leak coolant and drip onto the terminals of the battery charging alternator.
Consequence: This can result in a short in the electrical circuit and the potential for an engine compartment fire.
Remedy: Detroit diesel will notify owners and repair the engines by replacing the low pressure regulator gasket with an improved gasket free of charge. The recall began on April 7, 2006. Owners may contact detroit diesel at 313-592-3708.

Has your Orion been repaired?

Recalls here come from NHTSA’s records for the model and year. Not every vehicle of a model is included in every recall, and this site can’t see whether a repair has been done. Only a VIN lookup can tell you that.

Check your VIN with NHTSA

NHTSA’s VIN search doesn’t show recalls that were already repaired, recalls more than 15 years old, or some small manufacturers’ recalls. A Orion dealer can also check your VIN. Recall repairs are free.
