Buying a Used Jeep Liberty CRD

Life, Liberty, And... The Pursuit Of Compact Diesel Power

We recently got the itch to find a compact, fuel- efficient, yet four-wheel-drive vehicle here at Diesel Power. Judging by the title of this article, you can see that our search led us straight to this inferno-red ’05 Jeep Liberty CRD. The $14,000 price tag and 32,000-mile odometer reading didn’t hurt matters and were more or less the icing on the cake.

The Jeep is powered by a VM Motori 2.8L inline-four engine with common-rail injection and backed by Chrysler’s 545RFE automatic transmission. The short-lived Liberty CRD was only offered for the ’05 and ’06 model years, and due to emissions regulations, it wasn’t sold in California or New York (the two most populated states). Despite the short production run, and amidst many car experts giving them less-than-satisfactory reviews, the people still chose dieseland Chrysler sold every unit it produced. First and foremost, our mission is to prove the naysayers wrong about these little machines. We’ll also be addressing some weak links, adding some power, and keeping a fuel economy log, so stay tuned for future updates.
Longevity Tips From The Pros at Green Diesel Engineering:
Problem: Fix:
EGR system (dirty intake and decreased fuel economy) Modified ECU (disables EGR, adds performance)
Intercooler hoses crack (no silicone lining) Samco silicone replacements
Fuel/water separator (allows air intrusion) Mopar upgraded unit with wiring kit
Weak factory torque converter (inferior lockup clutch fails) Mopar European-spec or Sun Coast Converters upgrade
