There are a few reasons for oil being in your antifreeze, 1 blown head gasket 2nd cracked head,3rd warped head, and a crack around the head bolt thread allowing oil to be pushed into the antifreeze. Last could be a hair line crack in the cly wall

Car overheated and lost all power. how do I get it to start?


ENGINE NOT GOING TO START IF GET TOO HOT FIRST THING I WOULD REPLACE THERMOSTAT AND RADIATOR PRESSURE CAP THEN ADD COOLANT UNTIL COOLANT LEVEL CORRECT THATS WHEN THERMOSTAT OPEN UP AND TOP HOSE HOT.CHECK FOR LEAKING RADIATOR HOSES CHECK TOP RADIATOR HOSE CHECK BOTTOM RADIATOR HOSE.CHECK FOR LEAKS AROUND THE RADIATOR LOOK DOWN BELOW COOLANTS FANS CHECK FOR LEAKS AT RADIATOR CORES OR LEAKS AT THE RADIATOR PLASTIC SIDE CONTAINERS. CHECK FOR LEAKS AT WATER PUMP WEEP HOLE AND CHECK FOR LEAKS AT THE HEATER HOSES AROUND ENGINE BLOCK TO THE HEATER CORE HOSES. THERE IS A REASON CAR OVERHEAT.IF CAR OVERHEAT WHILE DRIVING YOU HAVE FAULTY THERMOSTAT OR LEAKING OUT COOLANT OR BLOWN HEAD GASKET.IF ENGINE OVER HEAT WHILE SITTING DURING A LONG IDLING PERIOD.YOU COULD HAVE FAULTY COOLANT TEMPERATURE SENSOR OR FAULTY COOLING FAN FUSE OR RELAY.HOT WIRE COOLANT TO SEE IF IT RUNS IF NO REPLACE FAN MOTOR. IF YES FAN MOTOR COULD HAVE FAULTY WIRE OR PCM FAILURE. CHECK ENGINE CRANKCASE IF OIL LOOKS LIKE MILK SHAKE ENGINE HEAD GASKET LEAKING.

My son has a 1998 ford escort and it was overheating. I replaced the thermostat,but it is still overheating. What could possibly be the problem?


Believe it or not, you can fix this with a floorjack. The heater core hoses are higher than the top radiator tank and as we know, water seeks it's own level. If you raise the front of the vehicle about 10-12 inches, this will allow the coolant to fill the airspace within the heater core. Run the vehicle until it is at normal operating temperatur with the radiator cap off. If there is no radiator cap than remove the one from the overflow tank/ reserve. Now, if the car is running very rough and you see a lot of steam coming from the radiator or the exhaust than his car has blown a headgasket. Thank you, Dana

What causes the lost of coolant antifreeze?


loose hose clamps, hoses with holes in them,hole in radiator,blown head gasket,missing radiator cap,leaking heater core, bad gaskets where coolant passes. check your oil make sure its not turning to milk and level is getting higher. other than this you need (sherlock holmes).
