How to replace water pump on 1994 4 cylinder Camry?
You need to remove the front timing belt cover. May need to remove
motor mount on passenger side to get the top half of the cover off.
Jack up and support engine to remove mount. Mark the timing belt on
the camshaft and on the crankshaft so that it can be replaced
without changing the timing. Remove the timing belt and you can
change the water pump. Nothing difficult, just time comsuming.
