#Coolant leaking from water pump install

Slip a couple of bolts through the pump for mounting holes to hold the gasket in place.ġ4. Apply a thin layer of RTV sealant to the gasket mating surface of the new pump, then carefully mate the gasket and the pump. you can find it at wal-mart, or any place like that.)ġ3. Apply a thin coat of RTV sealant to the engine side of the new gasket. Clean the engine and new water pump mating surfaces with lacquer thinner or acetone.ġ2. Remove all traces of old gasket material from the engine with a gasket scraper.ġ1. If any fins are missing or badly corroded, replace the pump with a new one.ġ0. If the old pump is being reused, check the impellar blades on the backside for corrosion. On six-cylinder models, remove the heater hose fitting from the old pump and transfer it to the new pump, using sealant on the threads. Compare the new pump to the old one to make sure they're identical. Clean the bolt threads and the threaded holes in the engine to remove corrosion and sealant.ĩ.

It may be necessary to remove accessory drive brackets for access to the hose.Ĩ. Note: On six-cylinder engines and 5.2/5.9L V8 engines, be sure to check the condition of the bypass hose and replace it, if necessary (it's a good idea to replace it regardless of its apparent condition). On 5.2/5.9L V8 models, reach above the water pump with pliers to release the hose clamp on the bypass hose. Note the locations of the various lengths and different types of bolts as they're removed to ensure correct installation. Remove the bolts and detach the water pump from the engine. On six-cylinder models, remove the idler pulley and the power steering pump, don't disconnect the hoses and keep it upright to avoid spilling fluid.ħ. On 5.2/5.9L V8 engines, unbolt the coolant return tube from the top of the engine and pull the end out of the water pump.Ħ.

If the hoses are deteriorated, cut them off and install new ones. If they're stuck, grasp each hose near the end with a pair of adjustable pliers and twist it to break the seal, then pull it off. Loosen the clamps and detach the hoses from the water pump. (In case you don't know, loosen up the idler pulley and the belt will become easy to take off.)ĥ. Remove the drivebelts and the water pump pulley. You may have to bend the shroud a little bit, but don't worry. Pull the fan off of the studs, and pull both the fan and shroud out. remove the bolts holding on the shroud, remove the 4 bolts holding the fan to the pulley, and both will come up at the same time. If the coolant is relatively new or in good condition, save it and reuse it.ģ. Disconnect the negative cable from the batteryĢ.
