Pop noise I fear was a cooling system hose or radiator blowing out. I would say cylinder head is now bent gasket leaking and combustion into cooling system . a preasure test of each cylinder at TDC firing will verify this and specificly locate the main area of concern. Red lights on dash are the same as street lights red means stop or pay the consequences

sounds like you have a blown head gasket this would explain loss of coolant and running poorly excessive smoke.

SOURCE: how can you tell if your water pump is bad

It could be either hose or the pump. Introduce no more antifreeze to this car until you have found your leak as you are just wasting your money.

You are going to have to visually inspect it for the leak. Typically if it is a pump, the pulley and the underside of the pump will be wet.

SOURCE: Blowing ECM-B fuses

The ECM-B fuse is a 20 amp fuse, and you should NEVER put a larger fuse in to try to overcome any problem. The oil pressure switch is a secondary concern; there is an idiot light or oil pressure guage in the dash to alert you to oil pressure problems. Under heavy load, such as towing, your engine requires more fuel, and if your fuel pump is going/has gone bad, it cannot supply the demand.
The problem is almost certainly a fuel pump wire harness short, caused by a dying fuel pump. I have both had this problem myself, and repaired it on three other vehicles. On my vehicle, the wire harness had welded itself together when the fuel pump locked up, and the wire harness caught on fire.
The fuel pump is in the gas tank (of course my tank was full), and the tank has to be dropped to access it. The wire harness is modular, with plugs at both ends, and can be bought from the Chevrolet or GMC dealer.
If you put an incorrectly-rated fuse anywhere in your vehicle's electrical system, the WORST place to do it is where you have--the fuel pump circuit. Fuses blow for a reason, and the manufacturer's engineers properly size the fuses for the application at hand. Please don't do that again.
This can be a very dangerous problem and repair, and no, it is not cheap.
Do not attempt to operate this vehicle until you have had the problem properly corrected. Good luck.

High temp low oil pressure light comes on after driving for a few minutes, then off when engine at driving rpm. At stop light (idle or low rpm) light comes back on. Normal driving it goes out.


You need to find out why you have low oil pressure. It is normal that as engine rpm's increase, the oil pressure will rise- the oil pump is moving oil faster. Even though your light goes out, you could still have critically low oil pressure. There should be sufficient pressure at idle to keep the light off. The light will come on when your oil pressure is almost nil- I believe for some it's as low as 8 psi. Normally, oil pressure at idle is specified anywhere from 15 to 40 psi. You would have to check specifications for your Expedition. To verify oil pressure, hook up a mechanical gauge at the oil pressure sending unit on the engine block. Check with a local shop.

The causes run from easy, simple to budget busting ruin. Low oil level, wrong grade oil, real old oil, oil leaks, internal oil leaks, worn oil pump, worn crankshaft bearings. It was pretty common on older very high mileage cars to have a fluttering oil light at stops and idle. It was time for a rebuild, or time to look for another car.

My coolant light come on 05 Saturn Ion - no visible leak but - filled with antifreeze but it keeps evaporating??


It's probably dripping only when you are driving such as from a weephole where the water pump is located or it may be leaking onto a hot surface so the moisture evaporates, but will leave a stain. You should turn the vehicle off, let it cool and use a leak
pressure test with a tool you get from the parts store (they will let you buy a used one and take it back for full refund). You pump it up and then look closely with a strong light for any drips while there is pressure in the system and the vehicle is turned off.

99 Sunfire Coolant keeps dumping


You need to find the source of the leak. it hasn't overheated yet because you keep catching it and re-filling. From your description, it sounds a lot like a bad water pump seal (part of pump) but without physically looking you can't be sure of that. when the pump seal begins to fail, internal pressure while running often will drive the seal tighter against the shaft stopping the leak. as pressure drops as the engine cools, the seal relaxes and permits seepage.
With time, that will change and it will leak all the time.

Temperture gauge at hot coolant is full


You may need to replace the thermostat or water pump, even flush out the system. Best thing to do is to flush out the system with radiator flush and follow the instructions and replace the oil antifreeze with new one with a 50/50 mix (water/antifreeze), if you not sure how to do that you can buy them premixed. Next is to replace the thermostat and radiator cap, that should fix the problem. The last thing would be the water pump is weak and would need to be replaced but lets start with the simple., The other thing to if it's only hot when your at a stop light then check the fuse and relays and wire harness to your radiator fan to make sure it's working. If you turn on your A/C that would over ride the temperature sensor and activate the fans so you know that is working, so if's running hot all the time even when your driving, replace the thermostat and coolant. Good luck.

Overheating


Make sure you don't have a bad head-gasket. Check for excessive pressure in radiator or hoses. Check under oil cap for creamy/milk like residue or actual antifreeze in oil or the opposite oil in antifreeze. Let me know what you find. Good Luck

Where does the water/antifreeze go?


drain the oil and watch the oil when it drains. if you see antifreeze then your head is cracked

Melted spark plug wire


You did not say if you were overheated,also what liquid and what is meant by spark plug filled with liquid, if plug was removed from block! (antifreeze?) Check oil and if water in it you more then likely have a blown head gasket. Hot engine is what most likely caused burnt wire. They make sealers that are put in radiators to repair leaks if cost is a problem and you are comfortable using them, and if not, have head gasket replaced which can be quite costly. Mechanic can determine cause with a compression test. Other things you would be wise to consider if installing new head gasket would be changing water pump,timing belt and crankshaft seal as while as the other belts that need changing.Of course this would depend on whether you planned on keeping the vehicle and if it was worth it. You can talk with a mechanic about using a sealer if this is the problem. I know of no other liquid it could be other then antifreeze.Oil is unlikely. P.S You might want to find out where the oil leak is and correct it before you do more damage!
