The Jeep Liberty 2.8L CRD is popular all over Europe and was Chrysler’s way of testing the waters for diesel-powered SUVs in America back in 2005. It was a success, as the automaker actually sold out of them before emissions requirements led to the cancellation of production in the states. The Jeep Liberty 2.8L CRD is popular all over Europe and was Chrysler’s way of testing the 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 Liberty CRD Specs: Year: ’05 Jeep chassis designation: K Trim: Sport, Trail-Rated Engine displacement: 2.8L Injection system: Bosch common-rail (23,200 psi maximum pressure) Injection pump: Bosch CP3 Engine control unit (ECU): Bosch EDC16 Turbocharger: Garrett GT2056 V (vacuum-actuated, variable vane) Horsepower: 160 hp at 3,800 rpm Torque: 295 lb-ft at 1,800 rpm (some early models were dealer-derated to 260 lb-ft) EPA estimated fuel economy: 19 mpg city, 24 mpg highway Transmission: 545RFE, five-speed automatic Transfer case: NV242 Selec-Trac Axle ratio: 3.73:1 Steering system: Rack and pinion (a first for Jeep) Like most features on the compact Liberty, the gauge cluster on the dash is very simple and straightforward (limited interior space leads to limited luxuries). Here, the tachometer is displaying the VM Motori engine’s typical idle speed of 750 rpm, and only 32,535 miles are shown on the odometer. Like most features on the compact Liberty, the gauge cluster on the dash is very simple an The inline-four VM Motori engine features dual overhead cams, four valves per cylinder, and a timing belt. The 2.8L is known in the industry as an “interference engine.” This means if the timing belt breaks, catastrophic engine failure can result. This can happen when the pistons and crankshaft keep moving while the camshafts and valves stop—leading to piston-to-valve contact. However, VM Motori is said to have engineered its finger- followers on the camshafts to be the weak link, and they are much more likely to break than a valve in the event of a timing belt failure. The recommended timing belt change interval is 100,000 miles. The inline-four VM Motori engine features dual overhead cams, four valves per cylinder, an Because the Liberty CRDs came with aluminum oil pans, it’s very easy to overtighten the drain plug. To rule this out and ease oil change intervals in the future, we added this Fumoto drain valve for $21.95. By simply lifting the lever and giving it a quarter of a turn, you can drain the crankcase without the need for tools, and without getting oil on your hands. Our first oil change called for 6.4 quarts of Shell’s Rotella 5W-40 synthetic oil and a Mopar oil filter (PN 5003558AA). The air filter (PN 5018777AB) and fuel filter (Napa PN FIL3647) were also replaced. Because the Liberty CRDs came with aluminum oil pans, it’s very easy to overtighten the dr SOURCES Mopar P.O.
