I have a 1994 Ford Probe with 93,000 miles; made in Canada. The water pump needs replaced. I've been told I might as well replace the timing belt too. The timing belt housing has to come off to replace the water pump. One repair shop wanted to replace the timing belt, timing tensioners and idlers,the hydrolic tensioner assembly, and camshaft and crankshaft seals. A cost of $560 in parts. What parts should I replace? Is there more I should replace?
Also, can I use a computer scanner on my car? I don't know if it has a computer.
