Villager/Quest mailing list member Dale Wadding has also changed his timing belt. And he took some wonderful pictures. Here is his text and pictures:
I replaced the timing belt and accessory drive belts on my 1993 Mercury Villager at 64,000 miles. I replaced the timing belt tensioner because of some bearing like noise that I felt could be coming from the tensioner. I did not replace the water pump, since the '93 models have a 60k replacement cycle on the timing belt and I felt comfortable waiting to replace it at the 120k mark. I replaced the thermostat since the reading on my dashboard was running below the "L" of NORMAL - - after replacement it runs between the "A" and "M".
I purchased Dayco belts and the tensioner from Wrenchead.com and was satisfied with their prices and service. Just for reference, I was quoted $30-35 for the timing belt from Mercury and Nissan dealers and paid less than $20 from Wrenchead.com. I have also purchased parts from Carparts.com and been satisfied. Use caution when ordering online - - call their parts specialists to make sure you order the correct parts, and allow plenty of time for delivery.
Prior to starting the job, I reviewed and printed all of the excellent material on the Villager/Quest FAQ at Steve Cutchen's website.
CAUTION: Use good safety practices! Wear safety glasses. Jack and support the vehicle carefully. Maintain a clean, well lighted work area.
I didn't follow the exact order of removal listed in the factory service manual. Use whatever works for you, but here's the procedure that worked for me:





When refilling the engine coolant, I tried to follow the procedure from the FAQ. But my Villager didn't have the heater pipe air relief cap, so I just vented the radiator & engine air relief plugs and it worked fine.
8-10 hours is probably a good estimate of the time required for this job. But don't rush things - - doing the job right is more important. My engine is much quieter after this work, the noise around the distributor is gone.
