Mercury Mariner Water Pump
Mercury Mariner vehicle's Water Pump is instrumental in circulating water from the radiator to the engine block where the heat produced through combustion is absorbed. Majority of models employ the use of aluminum castings with an articulated shaft and an impeller to circulate the coolant. The signs of a faulty Water Pump are concessions, noises that originate from the bearings, and excessive heat present in the engine. There are new high-intensity Performance Water Pumps to perform on high-intensity engines providing coolant flow and consuming low energy than the regular pumps. Electric Water Pumps are also an option, which has advantages like coolant circulation with or without the help of an engine and post shutdown cooling.
We provide a wide range of Mercury Mariner Water Pump at the best prices possible. If you need Mercury Mariner Water Pump, you can shop with confidence on our website. All our OEM parts come with a manufacturer's warranty and are delivered to your door step with a fast delivery service.
Mercury Mariner Water Pump Parts Questions & Experts Answers
- Q: What are the signs of a failure in the water pump on Mercury Mariner?A: A failure in the water pump can cause serious engine damage due to overheating. If a failure occurs in the pump seal, coolant will leak from the front cover (four cylinder models) or the water pump housing (V6 models). Water pumps are equipped with weep or vent holes. It is possible to check the water pump weep hole using a flashlight. If a failure occurs in the pump seal, coolant will leak from the hole. Use the flashlight to find the vent hole on the water pump and check for leaks. If the water pump shaft bearings fail, there may be a howling sound near the water pump while it's running. With the engine off, shaft wear can be felt if the water pump pulley is rocked up-and-down. Don't mistake drivebelt slippage, which causes a squealing sound, for water pump bearing failure. A quick water pump performance check is to put the heater on. If the pump is failing, it won't be able to efficiently circulate hot water all the way to the Heater Core as it should.
- Q: How to replace a water pump in a Mercury Mariner?A: Disconnect the cable from the negative battery terminal. Drain the cooling system. Remove the drivebelt on four cylinder models or the water pump drivebelt on V6 models. Loosen the right front wheel lug nuts. Raise the vehicle and secure it on jackstands. Remove the right front wheel and the fender splash shield. Remove the water pump pulley. Remove the bolts attaching the water pump to the engine block and remove the pump from the engine. If the water pump is stuck, gently tap it with a soft faced hammer to break the seal. Clean the bolt threads and the threaded holes in the engine and remove all corrosion and sealant. Remove all traces of old gasket material from the sealing surfaces. Remove the air filter housing. Remove the water pump drivebelt tensioner. Remove the water pump mounting bolts. Clean all the gasket and 0-ring surfaces on the pump and the housing. Remove the outlet air duct from the air filter housing. Remove the water pump drivebelt. Remove the lower radiator hose from the thermostat housing. Remove the three mounting bolts, then separate the water pump from the housing. Discard the water pump gasket. Clean the sealing surfaces of the housing and the pump. Remove all traces of old gasket. Compare the new pump to the old one to make sure that they're identical. Apply a thin film of ATV sealant to hold the new gasket in place during installation. Install the water pump bolts and tighten them to the torque listed in the specifications. The remainder of installation is the reverse of removal. Refill the cooling system. Reconnect the battery. After you're done, the Powertrain Control Module (PCM) must relearn its idle and fuel trim strategy for optimum driveability and performance. Operate the engine to check for leaks.
