I have a 1997 Mazda Protege LX, 4 cyl. 1.5L engine, about 151,000 miles. I am about to change the timing belt on it, and would like to know what all I need to get. I know I need the belt (of course), a water pump, and a tensioner and idler. Should I also get a camshaft seal or crankshaft seal or both? And what brands would you recommend, because I saw on DIY Auto that I could get a timing belt for under $30 dollars. Thanks a lot!
