find the washed bottle usually done by removing the drivers side wheel and crud guard and there it is.... then find the pump and pull it out the tank a simple tug will be sufficient.... then if the level of the fluid is above the motor it will go everywhere lol... but then once it has stopped fit the new pump with a good push and ensure that it pops in nicely and is sealed.... before fitting it all together try filling it up and checking it works and if it leaks from the side apply some vaseline or grease to the seal and pop it back in... test again and then if all is good put it all back together and enjoy having a clean window!
