Locate the air filter box. From the box, there should be a large hose going toward the engine (air intake). There will be a few fasteners around the hose holding a smallish black box off to the side. The MAF sensor is inside that large hose, near that black box. It should be in the center of a plastic circular harness within the hose once you disassemble it. Be careful with the sensor, they are extremely sensitive to solvents. Use MAF sensor cleaner ONLY if you want to clean it (recommended for better MPG around every 20-50K miles). Hope that helps!

No visible leaks--- BUT--- you see some coolant around the intake !!!!? Your going to have to realize that the water pump can leak,the intake may leak & a head gasket or radiator,hoses, etc can leak We can not do the checking & guessing for you

Have the cooling system pressure tested. If it holds pressure, that's a good thing. If it doesn't hold pressure, you may have a leaking head gasket. What may be happening is the crack in the head gasket could be blowing hot air into the cooling system causing it to overheat.

Check for ruptured hose or loose clamps. If they look ok your waterpump may need to be replaced.

Try and locate the fuse that controls your brake lights. If you have no service information inside an owners manual, remove each fuse one at a time to check for any burnt out. Do not switch any fuse locations, or replace any fuse with a different amperage rating. example, if you find a 10A fuse that is burnt, replace it with a 10A fuse only. If you cannot find any burned fuses, you should probly replace your brake switch underneat your dash. Your brake pedal will hit the switch, so you shouldn't have any problems finding it. It will be small and black

I would look for a draw that is killing the battery.

It sounds as the voltage regulator which is built into the back of the alternator has stuck. Occaisionally this even happens on new ones. Would suggest taking the alternator back as it shoud be under warranty.

You can run without a thermostat in the summer time but not in the Winter time
