Low coolant light will also come on if you have an air lock in the water system,take of the clip on the highest hose,and fill from this point.any air in system will be obvious.

My 2002 envoy engine locked up while it was parked????


It can happen. Usually caused from the oil being low or going low to many times. When it cools down, the bearing will seize on the crank shaft. Also seen the A/C compressor lock up and keep the engine from turning. Both can be checked.

Does a water pump gasket problem lead to other gasket problems- such as intake or head gaskets/ and is it associated with having coolant loss issues?


If the low coolant from the water pump leaking has caused the engine to overheat, then the cylinder head(s) can warp and the head gasket(s) will leak also.

1999 ford taurus- yellow engine warning light keeps showing cylinder 1 misfire. I have: 1. Changed out plugs and wires, 2. switched wires around, 3. replaced fuel injector, 4. replaced coil. Still...


Yes.
You could have a leaking head gasket or a crack in the cylinder head.
After driving the car for a few days the spark plug should show signs of coolant on the tip.
You may want to do a compression test to see if that cylinder is low on compression too.

Engine coolant level drops on Mercedes C180 2001 model


Loss of coolant is serious because if you allow your engine to overheat you can cause very expensive engine damage - thousands of dollars of damage (not hundreds).

The items that need looking at are:

- Radiator cap is old and faulty. This can allow coolant to escape and needs to be replaced every 4 or 5 years (sometimes sooner) with the correct spec cap - not any old product picked up at some auto store.

- External leak - you need to check all flexible coolant hoses and connections for leaks as well as around the water pump to ensure the WP gasket is not leaking

- Internal leak
The most common is a blown cylinder head gasket which can allow coolant to escape and to get into the cylinders and into the lubrication system. If getting into the cylinders you will see white smoke coming from the exhaust . You need to check the engine oil for coolant contamination as a coolant can escape into the lubrication system via a damaged head gasket. You also need to check the coolant for signs of oil escaping under pressure via the blown head gasket into the cooling system.

An internal leak can also be caused by a cracked cylinder head but if you have this condition are blown head gasket will have probably occurred around the same time.

How much will a head gasket for a 2000 ford taurus cost


if it is just one and the mechanic is reasonable and there is no other damage ,ie main bearings, valves, cylinders scored, around 800 per head gasket and if one head needs to be shaved you better get the other head shaved and gasket replaced..i had my 2000 taurus done for 1200 couple years ago. it ran for a few years then developed low compression from the coolant leaking into the cylinders..never had luck with mine hope you are having better luck

Your vehicle is what...16 years old? Parts do not last forever. I can't see changing the pump twice unless the old one was defective. There is no reason to replace a pump unless it leaks or is noisy. OK, now the low coolant light is on. Is the coolant low? Is the engine running hot? Low coolant sensors have been notorious for failing. If the level is good and it's not overheating you can either remove the indicator and replace it or just disconnect it and routinely check all your fluids (you should be doing that anyhow) once a week. Cars did not have or need that sensor for many years. Gas stations used to check fluids when they actually could afford to have people pump your gas for you. It only takes a few minutes and isn't a difficult task to check everything over now and then.
If you have found the level to be low, re-fill it and check again for leaks. White smoke from exhaust can mean a bad cylinder head gasket as can oil in the coolant or coolant in the engine oil. I've found some vehicles (including one Jeep I own) that will not keep the overflow full but never overheats or has problems. Some head gaskets deteriorate and begin to seep coolant on the outside of the engine. That kind of leak often evaporates on the side of the block and never drips on the ground. Check around the head/block parting line. If you find a crusty white or greenish residue there, run the engine and watch that spot. If it gets damp there, it's leaking. As long as it continues to run well and the temp stays normal, everything should be OK.

the problem could be as simple as a faulty radiator cap from your description the water that is expelled when it gets hot is not being drawn back as the radiator cools down
could be a leak in the reservoir hose
I am thinking that the low coolant sensor in the top of the radiator tank is getting an air space and that is what is activating the light
I don't think it was head gasket problem as you would be overheating or loosing coolant within days not weeks I would go to an accredited radiator specialist shop and have a pressure test done for leaks in the system including the water pump leaking when running
I am saying that the vacuum created as the coolant cools down is not as good as it should be to draw water back from the reservoir to keep the radiator full to the cap
