1996 Satern is leaking coolant from bottom of engine?
I checked the thermostat and hoses that I could see. After looked from under and saw coolant leaking from what looks like an inspection plate?. Is there a hose that can be cracked in there? Or do you think it's something bigger? How can I check it without disassembly of all the belts and hoses? Please help, I wanted to make it to my dads for fathers day. Thank you so much!!!!

Possibly a hose or a freeze plug. Yes, the coolant will go into the engine when it is off and the thermostat closed. As you fill the radiator, coolant will go into the engine through the bottom radiator hose. Keep looking-save your coolant and use water till you find where it is leaking. Stick a garden hose into the radiator, turn it on low, then you can see or feel where the leak is.
Usually this is a simple fix like the upper or lower radiator hose leaking or just a loose clamp at one of these hoses. Get a bright flashlight, upon the hood and check the hoses at both ends. Make sure the engine is off. You might have to lay under the front of the car to look at the bottom hose. These hoses are the usual suspects start here. If these look ok and are not leaking look at the front of the engine where the belt is for any coolant dripping. If so this could be the waterpump leaking. If u plan on doing this job yourself I think u should watch a video on utube on how to do it. Good luck
check all your hoses run vehicle for awhile the inspect hose in this area. look for obvious things next check at the engine to see if a freeze plug is leaking then inspect you heater assembly the core may be leaking I'm leaning toward a hose or shut off valve
SMOKE UNDER HOOD COULD BE COOLANT LEAK FROM RADIATOR ITSELF OR CHECK FOR LEAKING TOP RADIATOR HOSE AND CHECK FOR LEAKING BOTTOM RADIATOR HOSE.LOOK UNDER THE HOOD IF COOLANT BOILING OUT COOLANT OVERFLOW JUG ENGINE OVERHEATING FROM BAD THERMOSTAT OR BAD WATER PUMP.CHECK FOR COOLANT LEAK AT WATER PUMP WEEP HOLE.IF SO WATER PUMP NEED REPLACING.ADD MORE COOLANT UNTIL LEVEL CORRECT.TRY LOCATE LEAK. IF CAR OVERHEATED AND BOILED IT OUT. SMOKE UNDER THE HOOD CAN ALSO BE CAUSED BY LEAKING VALVE COVERS WHICH CAN BE FIRE HAZARD IF OIL LEAKS ON HOT EXHAUST MANIFOLD.
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.
There are no coolant lines etc running on the lower part of the engine. Usually water will leak from above and run down finally dripping from under the engine. Coolant will not leak from the "engine" it leaks from a hose or thermostat housing.
Start from the top and work down. Check each hose by feeling with your hand. Look for a wet spot. wipe the hosed with a cloth to clean if necessary. If you think you found it dry the area and check again. Sometimes you need to move the hose around to open a small tear and expose the leak source.
If a hose leak tighten the clamp. If torn hose you may be able to disconnect, cut the end and reattach. If too short replace.
Check where each hose connects to the engine. This will be the thermostat housing and the heater supply line. If a housing try gently tightening (careful they crack). Or replace the gasket.
If you don't see a leak at all. Start the engine and run. This will build pressure in the cooling system. Look for leak using the same process. Careful as the engine is hot.
Check for radiator leaks, hose leaks, try to locate the area were the leak is occuring. You may need a new thermostat. If you can locate were the leak is, chances are you'll find the area in need of repair.If coolant is running from small line " hose from radiator or coolant bottle", could be a faulty thermostat.
