Glow plug and harness kit for the Jeep Liberty CRD. Includes OE Mopar glow plug harness along with 4 BOSCH glow plugs.
The Jeep Liberty CRD came from the factory with 7-volt glow plugs. Some Jeeps were recalled and the 7-volt plugs were replaced with 5-volt plugs as part of the recall program.
** PLEASE NOTE ** Based on customer feedback and our own testing with cold starts, we recommend the 5V plugs regardless of programming. Using 5V plugs with 7V programming will not cause a check engine light. Running 5V plugs at 7V may reduce life and will void the warranty, however, many owners have run the 5V plugs for many years so far without issue. Whatever voltage you choose, all plugs must match.
The 5-volt plugs are made by Bosch.
