How do you tighten the power steering pump belt on a 92 Mazda Protege?

The older models with two belts have lock bolts on the tensioner bolts that must be loosened before you can turn the long tensioner bolt. You will need to loosen the lock bolts a turn or more and then loosen the tensioner a good number of turns until you can get enough slack to remove the belts. Organizing screws, bolts & tools helps a lot.

Remove the bolts holding the power steering pump by unbolting the 3 bolts to release the power steering pump bracket from the engine (12mm and 14mm), but without opening or unsealing the power steering hoses or you will need to drain it and refill it when finished. This will help get some working space, where it is difficult to loosen and tighten the lock bolt on the power steering tensioner with a combination wrench (14mm) even by switching ends of the wrench. Do not pry belts off or on.

9Loosen the long bolt of alternator pivoting bracket on the alternator belt; so it will allow the adjustable accessory to pivot as tension is released, loosen the tensioner enough to remove the belt. The older models do have two flat belts (not v-belts) and the newer models probably have a single serpentine belt. Do not pry or force the belts to get them off; you will probably need it all loosened even more to get the new tighter belts on anyway.

10Follow serpentine belt instructions in your operator manual and see their diagram for that kind of belt, if so equipped on newer models. 1Remove two short 10mm bolts (all bolts should be hex-head, unless some newer models use Torx/Star bolt heads) holding the power steering hose on where it crosses the valve cover and work the hose toward the left out of the way for removing the valve cover in a later step. One of the 10mm bolt that will be removed later was covered (hidden) but is now "found" under that hose.

2Remove spark plugs use a spark plug socket with a rubber grommet inside the socket so that it helps to lift plugs them out of the deep access ports.
