how to change a water pump on a1990 celeca GTS
Judge I believe that his model is driven by the timing belt.
Ok yes it is driven by timing belt. Timing belt replacement is suggested at water pump replacement.
Your best bet is to get a repair manual for your car. Water pumps that are driven by the timing belt can turn into a rather intense replacement if you have never done one before. There is not much room for error and if not installed correctly major engine damage can occur. Do your homework before trying to tackle this one.
lookin' at your twin cam design, yes that bad boy is buried deep in there~ would require several hours disassembly just to see it~ oooof~
a picture is worth a few more words~
