Diesel Injector Testing
Delco Diesel Services can test most types of HEUI, EUI and Common Rail Diesel Injectors, cost will vary, but if we find they are out of specification and you purchase an exchange there is no charge for the test on the replaced injector.
Check & Advise Information
Delco Diesel Services offers a check and advise service for many Electronic Unit Injectors. This state of the art test procedure determines whether your injectors are worthy of reinstallation. If the injectors pass the testing criteria, new o-rings are available for installation. Should your injectors fail testing criteria, Delco Diesel Services can replace your injectors with top quality remanufactured injectors. Contact us to take advantage of this service with a potential for great savings.
*Please be aware that an Injector Check and Advise has no WARRANTY coverage. Upon testing (good) means that the injector appears to be in good working condition. It does not guarantee that it is. There could be internal wear issues that do not show up in the Check & Advise program.
