PowerSource engines for one ton and under applications carry our industry leading 3 year/100,000 mile parts and labor warranty. We also offer two upgrade options on the warranty:
Our Silver warranty upgrade changes the status of the warranty to full no fault status. This means that regardless of cause of failure, you're guaranteed a one time replacement and labor, under the terms of the original warranty. The cost is $149 extra.
Our Gold warranty retains the 3 YR/100,000 mile no fault coverage but increases the hourly labor allowance from $50/HR up to $100/HR. It also covers towing up to $100, rental car coverage up to $350 and replacement fluids up to $50. The cost is $349 extra.
