It does not have a belt.































You therefore do not need to change anything.































Water pump would be changed with a timing belt if it is driven by the timing belt not because it needs to be changed but to save the expense of removing and installing the belt again if the water pump failed.































Since you don't have a belt then there is no need to change the water pump until it needs changing [begins to leak or make noise etc.] No timing belt also mean no tensioner to change.































Note: A 6 cylinder Accord does have a belt.
