Hey the water pump just went in my 1998 toyota rav4 2litre. how do i go about replacing it ? i cant find anywhere on here

Your water pump is driven by your timing belt, can not be seen with out remove timing belt cover, to replace you will also have to remove timing belt, if timing belt has not been replace best to replace it now also, timing belt should be replace every 60,000 miles. make sure before removing timing belt that you mark where all pulley gear's are at, so when you install the timing belt back on there in the same place as before you move the timing belt, no need to mark water pump gear,good luck,hope this was very helpful.
