I have a 2000 Caravan with 191,000 km (120,000 mi)that has given very good service, with no problems. The van starts and runs beautifully, and gets the same 27 mpg (imperial gallon) that it did when it was new. It has the original spark plugs and plug wires, and the original fuel filter. I'm not worried about hurting anything by running the original plugs, but, could I be damaging the fuel pump by not changing the fuel filter? The owner's manual does not suggest any schedule for replacement of the fuel filter. Does anyone have any experience with problems caused by not changing the fuel filter? Does anyone have any ideas or suggestions for when it should be changed. Some interesting experiences I have had: The manufacturer recommends no transmission service, but Canadian Tire, who have done the service since new did a trasmission service anyway and added DEX 3 from a bulk tank. Fortunately, I discovered this forum soon after that and had the transmission flushed and all the fluid replaced with ATF+4. Now 100,000 km (62,000 mi) later, no transmission problems. Had the timing belt replaced at 180,000 km (112,000 mi) and they replaced the A/C drive belt at the same time, although there was nothing wrong with it. After that the caravan developed a squealing noise when the A/C compressor kicked in. Took it in for this and was told that the compressor need to be replaced at $1,255.00 I thought about this for a while and took it back and requested an OEM belt installed. I figured the $60.00 cost was cheap if it worked, and not too expensive if it didn't. The noise stopped immediately, and I was able to then get a credit for the installation and cost of the original belt since it was under warranty. I paid only the $9.00 upgrade price to the OEM belt. I love this van! Oh, and by the way 12,000 km (7,500 mi) oil/filter changes since new and it does not burn a drop of oil.
