Could you Please explain to me the best way to relace a water pump outlet pipe on a 1985 honda prelude (twin carbs -5 speed) The pipe runs from the waterpump back along the firewall side of the engine and has a bad leak , and i do not know if you need to raise or (pull) the engine in order to get to this pipe or possibley freeze plug ? i am not shure yet do to the fact i can not see up past the steering rack that well, i know it is coming from above the oil filter so i believe it is the water outlet or inlet pipe ? Any help would be very helpfull !! Thank you Rich

Hi.

Accessing that hose is a bit of a pain in the.... The hose is accessed from underneath the car. First you need to take off the air filter housing and the thermostat housing, thhen you finish the work working under the car. undoing the bolts that hold the the pipe and cutting or undoing thef heater hose and oil cooler hose (the hoses must be replaced afterward). Replace hoses and O rings keeping the hoses in place to finish the job.

Also follow these general instructions:-

Unfasten the negative battery cable from the battery post with an open-end wrench to prevent electric shock while replacing the water pump hose. Place a drain pan under the drain valve at the bottom of the radiator.Remove the radiator cap from the top of the radiator tank and open the drain valve at the bottom of the tank with a pair of pliers to let the radiator coolant drain out. From underneath the vehicle, locate the water pump directly behind the cooling fan.

Close the drain valve and move the drain pan underneath the water pump. With a screwdriver, loosen the screw clamp on the water pump hose and pry the hose off of the pump.Loosen the screw clamp on the other end of the hose, which is attached to the metal outlet flange on the bottom of the radiator. Pry the hose off the metal flange with the screwdriver and remove the screw clamps from both ends of the pump hose.

Discard the old water pump hose and slide the metal screw clamps onto both ends of the new water pump hose. Attach one end of the hose to the metal flange on the bottom of the radiator and the other end to the outlet flange on the water pump.Secure the ends of the hose by sliding the screw clamps over the metal flanges about a half inch from the ends of the hose and tightening the clamps with a screwdriver. Fill the radiator tank with a mixture of half water and half coolant.

Secure the radiator cap to the top of the radiator tank. Fasten the negative battery cable.
