It sounds like you have a leak. I have seen the water pumps go bad many times. However I would inpect hoses and hose clamps. If okay place a piece of white cardbord under vehicle. Let vehicle idle for 20-30 minutes and inpect for liquid to hit the ground. Once found see if you can locate where the leak is coming from. If you don't see any coolant leaking I would supect a leaking heater core or leaking headgasket. You can also have a shop pressure test the radiator if none of the above works.

My 2000 plymouth neon is overheating, it has a leak near the radiator cap


if you keep going , instead of needing a new radiator , you will need another engine
temp gauges do not read with out water to make them work and if the temp keeps going up after refilling the radiator , it could be a head gasket or cracked head result

Tip

95-2001 plymouth voyager water pump


For all dodge minivans 94 to 2001 (and others) with 3.0 ltr V-6. You're driving on the freeway your temp gauge starting to go up. You get off the freeway. when the engine is cooled down you discover that the coolant in gone. You refill the radiator and look for a leak but can't find one. You check the oil but its not foamy, so no coolant there. If all seems to be operating normally, check under the vehicle when the engine is warmed up. There may be a slight coolant leak on the passenger side near the front tire .When the water pump on these engines typically coolant will leak out of the pump thru a "weep hole" located at the bottom of the pump. Most of the loss occurs while driving so your only indication may be that small drip of coolant. The water pump is powered by the camshaft timing belt and is located under the timing belt cover and can not be seen, however any coolant leak, no matter how small, in the area just to the rear of the crankshaft pulley is almost surely a failed water pump and must be addressed immediately

Coolant leaks from my ford escape I have had it pressure tested and fitted a new cap When parked leaves a puddle of coolant


Always find the source first, The rear water ports are directly behind the rear lower intake bolts and the front ports are directly in front of the front bolts. The rear ports are cast into the lower intake manifold and are dead ends, air can get trapped in that area. In cold weather your thermostat may open slower, resulting in a pressure build up at the rear ports. Any trapped air will compress. Normal coolant system pressure occurs when the glycol is operating temperature. I would try refilling the system and getting the air out,the leak may only occur when the system is full. With a cold engine, open the radiator cap and add 50/50 mix, fill the resevoir to the low mark. Run the engine with the radiator cap off until the thermostat opens, the upper hose will be hot when the stat opens. Turn the car off and refill the radiator to the top. Sqeeze the upper hose to remove any air. fill if necessary. replace cap, run car again until it reaches operating temp. Now with a full system check for leaks. When replacing lost coolant should also have the heat at max temp. Get a good mirror to check for leaks. The outter mating surface of the rear water jacket gasket is flush with the block and the edge of the lower manifold, sometimes you can see where it blew out.

2001 plymouth neon heater won't blow hot air. only cold. we have changed thermostat, radiator cap and flushed radiator. not odor through vents or leaks on floor board(heater core)


There is a problem with your climate control. It is not allowing the vent to open that allows air to pass through the radiator.

Oil in my coolant system


it is likely the head gasket. it's seeping oil into the cooling system.

I have a 97 Plymouth Neon 4 cyl SOHC. I recently bought it and it keeps overheating. I replaced the thermostat, temp coolant sensor, radiator cap, and flushed the radiator twice. I also took it to a shop...


CHECK WATER PUMP WEEP HOLE IF LEAKING. BECAUSE OF SHAFT BEARING FAILURE CAUSE CAR TO OVERHEAT. MAKE SURE COOLING FAN WORKING CHECK FUSE AND RELAY.SCAN CAR TO MAKE SURE THE COOLANT TEMPERATURE SENSOR WORKING.IT CONTROLS FAN OPERATION.BESURE YOU ARE USING CORRECT COOLANT MIXTURE.YOU NEED 50 % ANTIFREEZE AND 50 % WATER. TO RAISE BOILING POINT.TOO MUCH WATER IN COOLANT SYSTEM WILL CAUSE CAR TO OVERHEAT.

Heated coolant being lost at resevoir


How much are you loosing? If its just a little that could be from nothing more than expansion. If you are loosing a lot that could be either from overheating (steam) which would suggest the water isn't circulating and cooling or from a head gasket leak causing air to be injected into the water jacket and displacing the water.

Are you getting any oil in the water? foam? does the water appear to be milky?

Where is the radiator cap on 2001 Olds Alero?


if you dont see a radiator cap then the cap for your resevoir tank also serves as your radiator cap, thats where you would put your radiator cleaner and dex-cool in at. it is pressurized just like a normally radiator is with a normal radiator cap on it so dont open it when its hot! the resevoir cap should also have dex-cool stamped on it

1998 Neon leaking antifreeze


There could be a leak in the radiator or the water pump. Or the overflow coolant bottle but that normally won't drain all of the coolant. Fill up the radiator when the car is cold and start the car and keep an eye on it to see where the leak is coming from.
