The water pump keeps the coolant flowing finished your engine.
A inundate pump is the Element that pushes the coolant wound up the engine and back into the radiator to algid it off. Whether a damp pump begins to activity wick, it can account your Nissan Maxima to overheat. You Testament call for to troubleshoot the baptize pump, though, to build certain that is the complication. The troubleshooting is relatively little provided you spring from a infrequent guide steps and a couple of tips.
Instructions
1. Test the coolant commensurate in the reservoir.4. Pump up the coercion tester until it reaches approximately 16 PSI then proof for any leaks time to come from the passenger side of the engine. If you see no leaks, allow the tester to sit for a few moments.
Provided they are not, include them repaired or replaced.
3. Turn the vehicle off and let on it to arctic down. Connect a force tester by opening the radiator cap and screwing the Correct adapter onto where the radiator cap was.
Provided it is below unabridged, top it off with coolant.2. Launch the vehicle and confess it to glowing up. Dash off positive that the cooling fans are turning on and off.
5. Check the bottom passenger side of the engine for a leak. The reason behind checking there is because that is the location of the water pump; and if the bearing is bad, it will leak from the weep hole. The weep hole is designed to open up and slowly drip fluid to denote when the bearing goes bad. Replacement is necessary when a bearing fails.
6. Check the flow of the coolant by opening the radiator and allowing the car to warm up.
7. Look through the top of the radiator: the coolant should flow towards the engine from the top of the radiator. If it is not flowing, this is a sign of a faulty water pump or thermostat.
8. Eliminate the thermostat, as a problem, by trying to squeeze the upper radiator hose. If it is hard to squeeze, there is a thermostat problem that needs to be repaired then rechecked. Wear gloves or use a cloth when squeezing the hose as it is hot. If the hose is soft, then either the water pump fins are broken, or they are spinning on the axle of the water pump. Water pump replacement is necessary when the fins fail.
