Leaking coolant from around water pump just put in new radiator on monday and no leaks from it or hoses, think is weap hole in bottom of water pump.

Hose ? The drain valve on the lower radiator ? The water pump has what's called a weep hole built into it. When the water pump fails water weeps out of that little hole to let you know it's bad. I think the ion probably has the water pump onth the front of the engine under the plastic cover ? ( not sure on that ) if it is the water will leak from behind that plastic cover making it look like its coming from the area where the oil pan and that plastic meet. It could get blown around by the cooling fan making it look a lot worse that it is. Check the lower hose and all the other coolant hoses for cracks or leaks as well as the entire radiator area ( sides, top, bottom ) check your rad cap when its cool and be sure the rubber seal on the inside of the cap is good and not cracked or dry rotted. If it is then when the water gets hot and pressure builds in the rad it will leak. When its cold it may not.

WAIT UNTIL YOUR ENGINE IS COLD,YOUR RADIATOR PRESSURE CAP IS LOCATED ON THE COOLANT OVER FLOW RESERVOIR, THATS WHERE YOU ADD COOLANT WHEN COOLANT LOW,YOU POUR COOLANT IN THE OVER FLOW RESERVOIR UNTIL COOLANT LEVEL REMAIN AT FULL COLD MARK DONT OVER FILL OVER FLOW RESERVOIR, WHEN COOLANT LEVEL STOP DROPPING WHEN ADDING COOLANT AND COOLANT LEVEL STAY AT COLD MARK ON THE RESERVOIR YOU RADIATOR HAS THE CORRECT COOLANT LEVEL IF COOLANT LEVEL KEEP DROPPING CHECK FOR COOLANT LEAKS AROUND RADIATOR AND THE TOP AND BOTTOM RADIATOR HOSES, LOOK FOR COOLANT LEAK AT WATER PUMP GASKET OR SEAL OR LEAK AT WATER PUMP WEEP HOLE IF YES REPLACE WATER PUMP.

IF YOU GOT TOO MUCH WATER IN COOLANT SYSTEM AND DONT HAVE 50 / 50 MIXTURE OF ANTIFREEZE AND WATER. WATER WILL EVAPORATE BOIL AWAY.CHECK FOR COOLANT LEAKS LOOK AT TOP AND BOTTOM RADIATOR HOSES LEAKS, CHECK FOR COOLANT LEAKS AROUND BOTH RADIATOR CONTAINER AND RADIATOR CORES LEAKING. CHECK WATER PUMP WEEP HOLE. IF LEAKING WATER NEED REPLACING, CHECK ENGINE CRANKCASE ANTIFREEZE WILL LEAK IN CRANK CASE OR LEAK IN THE INTAKE GASKET COOLANT WILL BURN WITH FUEL.MANY THINGS WILL CAUSE COOLANT LOST.

Check radiator and hoses for leaks. If no luck water pump may be leaking. Should see leaking from weap hole at bottom of pump.

If you are losing coolant first get a pressure tester and find out if your your system is losing pressure, if so look at your water pump to make sure it not leaking. it has a weap hole on it, you might check your heater core to make sure it not leaking, it will some times make a smell in your car if it leaks.Next check all your hoses and radiator cap. I hope maybe i helped you a little

TO FIX COOLANT LEAK.YOU HAVE TO LOCATE IT.BEST TIME FIND COOLANT LEAK WAIT UNTIL MORNING.ADD COOLANT UNTIL COOLANT LEVEL IN RADIATOR CORRECT. START THE ENGINE LET IDLE UNTIL START GETTING HOT.THEN TURN OFF ENGINE.COOLANT PRESSURE WILL PUSH COOLANT OUT WHERE LEAKS ARE.CHECK TOP RADIATOR HOSE AND BOTTOM RADIATOR HOSE.CHECK AROUND RADIATOR LOOK DOWN BELOW COOLANT FAN AREA BEHIND RADIATOR.LOOK FOR LEAKS AT RADIATOR CORES AND SIDE CONTAINERS.CHECK FOR COOLANT LEAKS AROUND WATER PUMP GASKET OR WEEP HOLE.CHECK FOR COOLANT LEAKS AROUND HEATER HOSES AND HEATER CORE.CHECK ENGINE CRANKCASE FOR COOLANT LEAKS.

It sounds like the water pump is leaking from the weap hole.
Double the hode connections, and hoses. If they look good then it most likely need a new wayer pump

Hi, if you have water from the pulley area, it may be coolant leaking from the vent hole, in the water pump. This would leak more when cold, than hot. The repair, would be a water pump replacement. This is a fairly easy job, the only possible obstacle, is the fan needs a special holding tool, to dissasemble it. Otherwise, removing the upper radiator shroud, belt, and hoses, there are 4 bolts holding the pump to the engine.It is imparative that the engine block is clean , (to the metal), before the new pump goes on, then a mix of 50/50 dexcool, and distilled water, to refill the cooling system. Good luck...Coop

CHECK AROUND WATER PUMP AREA.AND THERMOSTAT HOUSING FOR LEAKS.THE MECHANIC WHO PUT THE WATER PUMP ON MAY FORGOT TO PUT SEALANT ON BOTH SIDES OF THE WATER PUMP GASKET CAUSING LEAKS.LOOK AROUND THERMOSTAT HOUSING FOR LEAKING.IF THERMOSTAT SEAL WAS DAMAGE DURING INSTALLATION IT WILL CAUSE LEAKING.IF ALL LOOKS GOOD CHECK FOR COOLANT LEAKS AROUND RADIATOR .CHECK RADIATOR TOP AND BOTTOM HOSES FOR LEAKS AND CHECK HEATER PIPES AND HEATER CORES HOSES FOR LEAKS.IF ALL HOSES GOOD.CHECK FOR LEAKING CORE PLUGS.

Check the radiator and hoses for leaks. Also, look at the water pump and see if any coolant is leaking out of the vent or "weep" hole. If coolant is leaking from the weep hole, the water pump is defective and will need replaced. When checking hoses, look for cracks and leaks, especially around the hose clamps. Hope this helped and best wishes.
