How to remove a radiator 03 Mercury Mountaineer 4.0 engine V6 I checked the hoses they're good, but small drops of fluid is coming from the bottom of the radiator looking like it coming from the hose


What is the problem exactly?
If the radiator itself is not the source of the coolant leak why do you want to remove it from the vehicle?

You will certainly be able to locate the leak if it is from the radiator unit itself and in that event you will need to replace it.

If you have a leaking radiator hose or the hose is too loose on the bottom radiator neck then you replace the hose or tighten the hose clamp if it is the adjustable type.

If the radiator hoses connected to the radiator are the 2003 originals then they will definitely be well passed their use by date and should be replaced in any event.

My coolant is rapidly disappearing, and I have no clue why?


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.

Overheating


CAR OVERHEATING FIRST CHECK FOR LOW COOLANT IN THE RADIATOR COOLANT OVERFLOW JUG.IF COOLANT LEVEL IN OVERFLOW JUG LOW REFILL ADD COOLANT BACK TO THE FULL COLD MARK.PUT RADAITOR CAP ON COOLANT OVERFLOW JUG START ENGINE LET IT IDLE UNTIL IT OPERATING TEMPERATURE.MAKE SURE TOP RADIATOR HOSE GETTING HOT WHILE ENGINE WARM UP.IF TOP RADIATOR HOSE DONT GET HOT WHILE ENGINE IDLING YOUR THERMOSTAT COULD BE STUCK CLOSE CAUSING CAR TO OVERHEAT.IF TOP HOSE IS GETTING HOT.CHECK FOR COOLANT LEAKS CHECK TOP RADIATOR HOSE AND BOTTOM RADIATOR HOSE FOR LEAKS.CHECK FOR LEAKS AT THE RADIATOR CORES AND PLASTIC SIDE CONTAINERS.IF ALL IS GOOD ENGINE OVERHEATING WHILE IN A LONG TRAFFIC LINE, COOLANT FANS NOT COMING ON.COULD HAVE FAULTY ENGINE COOLANT TEMPERATURE SENSOR OR BLOWN COOLING FAN FUSE OR RELAY.COULD HAVE PCM FAULT.MAKE COOLING FAN ELECTRICAL CONNECTORS AND WIRING NOT DAMAGE OR BROKEN.

2000 Linc Cont overheating. I replaced water pump, thermostat, belt & tensioner, blew through top hose out bottom (rad not clogged). Top hoses hot, bottom hose cold.


Do you have any coolant flow thru radiator with cap off?

Is thermostat in correctly?

Do a Combustion Leak Test at radiator or cap,
on gases from coolant. You may have a Head
Gasket going bad

RAdior is leaking badly what do I do? One of the hoses seems to be broken, and seems like a huge leak on the bottom??? Need help asap contact me at downloadkris4free@hotmail.com


  • Turn off the engine as soon as you suspect a leak, to prevent the engine from overheating.
  • 2 Determine which radiator hose is leaking and exactly where the leak is coming from by looking for wetness.
  • 3 Purchase 1 gallon of antifreeze and the correct replacement radiator hose from your local auto-parts store or dealer. (Radiator hoses are not interchangeable. They come in specific sizes and shapes for your particular car model.)
  • 4 Wait for the engine to cool down for at least 20 minutes, before beginning any work on the cooling system.
  • 5 Place a large pan or wide bucket on the ground under the hose to catch the coolant.
  • 6 Use a screwdriver to loosen the hose clamps at both ends of the hose you are replacing.
  • 7 Remove the radiator hose by twisting and pulling where it connects to the radiator and engine. If the hose won't budge, use a utility knife to cut it off the fittings.
  • 8 Remove the hose clamps from the old radiator hose and slide them onto the new hose.
  • 9 Put the new radiator hose on. Spray the inside of the hose ends with WD-40 if the hose is hard to get on. Tighten the hose clamps.
  • 10 Refill the radiator and the coolant reservoir with a 50-50 mixture of water and antifreeze.
  • 11 "Burp the cooling system" by running the engine with the radiator cap off until the engine warms up. Keep the engine running until both the upper and lower radiator hoses feel warm (this indicates that the thermostat is open and the coolant is flowing through the entire system). Burping the cooling system allows any air bubbles to escape. Add coolant to the radiator as needed.
  • 12 Look for leaks. Inspect around the hose clamps for dampness. Tighten the hose clamps if there is any wetness.
  • 13 Put the radiator cap back on.
  • 14 Check the coolant level after driving, to ensure there are no leaks

    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.

    I have a 2001 subaru outback and appears to be leaking coolant from thermostat but not having loss of heat yet. Can gasket be replaced or do you have to replace whole thermostat? Also where can I find...


    This sounds most likely to be a lower radiator hose leak (very common). It may be just as simple as tightening the hose clamp holding the hose to the radiator. If tightening the clamp does not work, replace the hose. When replacing the hose you must first drain all the coolant from the radiator and engine. Once its all drained, loosen the hose clamps on the hose thats leaking, pull the hose off and replace it with a new one. Tighten down the hose clamps and add coolant.
