Most water pumps have a small vent hole on the bottom side of the pump. Inspect with a flashlight and check for staining (rust or color changes left behind after water runs away from the vent) related directly with that vent hole. Also check for play (side to side) in the input shaft (belt pulley or fan pulley Either of these conditions is an indication of a failed or failing water pump.

Why does antifreeze come out when the car is hot?

It has expanded as far as it can inside of the engine so it has to go somewhere! See if you have enough anti frez ( what till the engine cools down first ) or make sure if the mixture of water/anti frez is correct 30% water to 70% anti freeze . Check your thermostat. If the coolant is coming out of a weep-hole on your water pump, pump is bad. Check the hose clamps, soft hoses. plug up radiator, heater core. Even if you have had service done on your car, you may have and air pocket in your system, they didn't burp the system right, take it back. also make sure the antifreeze, "if a mix yourself fluid" has distilled water mixed with it. distilled water has a higher boiling rate than water with impurities, thus preventing boil out.

How do you check car thermostat in a pot of water?

Put thermostat in cold water on stove top. Turn on burner and when water begins to boil you should see it open if it is functional. Then prepare to be yelled at by your wife for doing it.

What is the problem when your brake pedal goes all the way down to the floor?

Check your master cylinder, if it is still full or even partially full after you have tried the brake pedal several times, it's probably the master cylinder. if either side of cylinder reservoir is empty then you have a leak somewhere. Fill up the reservoir and pump the brakes several times and see if fluid is leaking. If fluid leaks at back of master cylinder then replace that. Also check the inside of the rear backing plates for evidence of wetness from a leaky wheel cylinder (rear drum brakes).

Is it necessary to replace the timing belt and water pump when installing new front seal on a 1999 Toyota Camry?

No, it is not. But the cost of labor is so high that is a good idea to do it as well. There are times when you need to do it though. Check how close you are to next timing belt change. See if water pump has any leaks. Check condition of the timing belt.

How do you repair a leak in the pool liner you can not find?

First, eliminate obvious and visible leaks. Check for evidence of leakage or moisture. Check all fittings that go into or out of the pool pump, filter, or heater. Check for leaky pump lids, leaky valves, or leaky seals. Also check to make sure that your multi-port valve is not leaking water to the waste line. If it's possible to see where this backwash line empties, check to make sure that you don't see water flowing or dripping from here.
