Radiator coolant in resevoir is like a paste.

I noticed the other day that the coolant in the reservoir on my truck was low. When i looked inside, the coolant appears to be chunked up like a paste. Ive never seen this happen on any of my other vehicles so I'm wondering if this is bad?

Depending on the year and model, it could be somewhat normal. The newer style coolant will cause a crusty substance to form at the top of the radiator if the coolant is low.
You may want to have a mechanic take a look at it, and you may want to have it flushed and replaced with new coolant.
If it is really heavy it could block the passages in the radiator.

I have a 2011 Chevrolet impala and my coolant in the reservoir is evaporating within a months time of being filled. What could be the problem? Water pump?

Start with a "professional" coolant system flush. Sounds like there's a blockage somewhere. If you're putting coolant in the resevoir and not directly in the radiator, and it's disapearing, check the radiator. If radiator is full it's a blockage, if it's low/empty there's a leak.

Loses water from resevoir but not from radiator

So the level keeps dropping in the reservoir? If you have to keep adding coolant to the reservoir, the system is leaking or losing coolant somewhere. Have the system pressure tested to find the leak. Is the reservoir itself leaking? When the level gets low enough, first the reservoir will go dry, then the radiator level will start to drop.
Here's how the reservoir works: coolant is under pressure from the radiator cap seal. As coolant heats up from hot engine, it expands, and pressure forces the radiator cap seal up, coolant is forced into the reservoir-remember the hot mark on the reservoir? When car is shut off, coolant contracts, creating a vacuum in top of radiator. This vacuum works to suction coolant back from reservoir into the radiator, keeping the radiator topped up, and coolant should now be at the lower cold mark on the reservoir. It is a closed, sealed system. The only loss of coolant will be a very small amount of evaporation from the reservoir. If coolant level keeps dropping, there is a leak somewhere.

I believe I may have a bad hose leading to the resevoir that holds the antifreeze or maybe the resevoir itself is cracked?

It could be the hose. Unless your car has ever been hit on that side, the reservoir usually outlasts the hoses.
You can easily test the hose. Unclamp it from the reservoir bottle when the coolant is not hot, plug the end with your finger and hold the hose down lower than the other end that is attached to the radiator fill neck. Look for leaks.

To check for cracks in the reservoir, it's easiest to place a flashlight inside the bottle top and look at the outside of the bottle...if liquid can get out then light can too.

I just bought a 96 mark, message center reads low engine coolant but heat gage remains normal. coolant not low. doesn't seem to hurt anything, just annoying. low coolant sensor location?

Silly question, but have you looked inside the radiator? I asked becuse often coolant is checked by looking inside the coolant overflow reservoir. Sometimes the ovrflow reservoir will look like the coolant is normal, when it's low in the radiator.

Here's a link which will give you more info.

2000 Toyota Celica coolant reservior empty

I hate to tell you this but its possible...

You have a leak. Look around on the driveway and try to determine if you have an external leak as opposed to an internal leak. If you see no coolant on the ground, suspect a blown head gasket. Do not continue to drive this car in this condition. If it does indeed have a blown head gasket, serious engine damage will occur.

Check your exhaust for white smoke. Chances are good you have a blown head gasket and coolant is leaking into the engines combustion chambers and is essentially burning off. Also check your oil, if it looks like caf mocha, this will confirm coolant is leaking into the oil via the blown head gasket
