I bought the 2005 CRD with 95,000 miles for $1000 back in 2013. I got it for that cheap since the car would intermittently turn off and would not start back. I traced the problem to crank position sensor thanks to this forum. After replacing the CPS, the symptoms were almost resolved but still occasionally it would have trouble starting. I traced the problem to air in the fuel head, I had a first-generation fuel head which was leaking fuel and letting air in. The car sat most of the years and I would drive it maybe once a month or so around the block or just locally since it wasn’t completely reliable and I had no time to work on it with having 3 jobs and going to school at the same time. I have no background in cars. I work in healthcare as a Paramedic and critical care nurse. This is my first diesel and I have learned a lot from this forum. I finally completed my Bachelors in nursing and had a little time this summer until I pursued my master degrees so I decide to work on it. Originally, the plan was just to do the timing belt service, thermostats, glow plugs, new fuel filter head and Samco hose. But of course, that all changed when part of my glow plug was stuck in the head which turned in to me taking the head off to remove the glow plug. So, after over $4000 in parts alone, she’s finally done. It took 3 months since I only worked on it once a week due to school and work. I have my other car that I drive.


Here is the breakdown of the cost:
Timing belt, timing belt tensioner, timing belt idler pulley, timing cover gasket kit, new water pump, new lower radiator hose, new upper radiator hose, new fuel filter with 2nd gen filter head, Serpentine belt, idler pulley, serpentine belt tensioner, valve cover gasket, cam seals, new glow plugs, glow plugs controller, injector washers and o rings, Exhaust valves, intake valves, valve seats, valve keeper, valve springs, valve seals, new exhaust manifold gasket, new turbo manifold gasket, driver side and passenger side engine mounts, and new oil cooler coolant hose, head gasket, CCV hose, Hayden fan clutch, all new gaskets, Litens alternator pulley

$5100 Working on the liberty wasn’t too bad. You just need to be patience and work slow. It was easy for me since I had other vehicles I can use so I took my sweet time. I have saved a lot of money on labor by doing all this work myself. I was quoted over $2400 just for timing belt and head replacement not including all the other stuff I did along the way. The money I saved on labor went towards the Samco hose, intake/exhaust valve and weeks winter kit. I still have money left over that will go toward gauges and GDE tune that I will purchase later. Since I did everything myself I also covered and labeled the wiring harness. I also redid the corrugated plastic tube that goes over the harness. I did the two piece fan shroud mod and secured it with brass hinges for easy and quick installation and removal. I have everything wired up for my turbo gauge and oil pressure gauge. I just have to connect everything in the cabin that I will do it later. I also bought another 3.7L liberty limited ($300) that I will be swapping parts out of. I have already swapped out the airbox but will swap out leather seats and most of the interior and cosmetic stuff. That will be next summer project along with torque converter and transgo for the transmission.
