How do I change the thermostat

Easy, just pull out the old one and put the new one it. ;)

If you are having trouble locating the thermostat, just follow the lower radiator hose up to where it connects to the engine. That is your thermostat housing, and inside of there you will find the thermostat. It's also a good idea to drain the antifreeze from the radiator before you start so you don't have all of it fall on your garage floor or on the street or where ever you are doing the job. There is a plastic drain plug on the bottom of the radiator that has tabs like a wingnut. After you drain it, just open up the thermostat housing and replace the thermostat and gasket. Fill up the radiator WITH NEW FLUID and be sure to bleed the system using the bleed screw on the thermostat housing to get rid of any air in the system. Your local county govt or perhaps even your city dump should have some sort of waste facility that you can bring the old antifreeze to.

I have 90,000 miles on my 2003 Camry. What maintenance should I be doing?

Well normally with toyota you change your belts about every 90,000 and spark plugs every 100,000 and if you havent changed your antifreeze then you will, they say toyota red antifreeze is suppose to last 5 years but i would change it every 3 because it breaks down just like regular oil does. and i would get done the tranmission fluid normally you change that every 40,000 since its just like oil.

Soft plug at the back of the engine is leaking, what causes this?

you engine has about 10 freeze plugs,there were created to be pushed out by ice if your antifreeze wasn't strong enough and froze inside the engine,that way the ice didn't crack the block when it expanded.
what causes freeze plugs to leak is the erosion affects from the antifreeze we use today,when they tell you to change your antifreeze every couple of years,the freeze plugs take another shot of strong antifreeze again,they just rust up on the inside of the engine until they get a rust hole in them

When I excelerate or stop for a long period of time my car starts over heating, what do you think the problem is?

It could be a faulty: 1-Radiator fan, Check the fuse. 2-Bad Thermostat, Change the Thermostat 3-Weak Water pump, Change the Water Pump.
Easiest thing to do is see if the fuse to the Electric radiator fan is bad. If it's good, then start up the car and see if it goes on when the temperature starts to get hot. I think the fan activates around 190". If the fan does not turn on, check for lose wires and bad grounds to the electric motor. Take caution, fan may activate without warning.
If the electric fan works good, then change the Thermostat. It may have failed and stuck in the shut position. After changing the Thermostat and problem still there, good chances are that it's the Water pump that may be faulty.
Before you go all though that trouble, check the Antifreeze level, make sure you have lots in there and just don't look at the radiator antifreeze reservoir. Look in the filler cap and the radiator cap. The plastic can become stained making it look like it is full but it's really empty.
Good luck and hope this help. Oh don't buy any radiator flush, it may clean up any dirt that my be plugging up any holes in the system, you do have a 6 year old car.

2000 chev silverado 1500 overheating

have your antifreeze mix tested to make sure it is strong (a cheap tester can be bought at any parts store) if it is ok than run the truck with the radiator cap off and see if the antifreeze cairculates when the it gets hot (this says the thermostat is opening ok). If that is ok than you might have the system pressure tested to find a leak or maybe the radiator cap is bad. Good luck

I need to change the cooling

Antifreeze is antifreeze like salt is salt and sugar is sugar. Depending on where you live and how cold it gets will determine how diluted you need to go. You can buy an inexpensive antifreeze tester at an auto parts store. Usually down to -10F will suffice but if you are up near Canada go lower. The color is a dye and it doesn't do anything. VW wants you to think a red dye makes a difference, it doesn't. I have a 2001 Beetle and a 2001 Jetta that I have used Prestone antifreeze in for years and never had a problem I fill mine in through the antifreeze resevoir. I did have to replace the water pumps in both vehicles last year as it was leaking and not pumping the fluid through consistantly. If you want to change the antfreeze there should be a plug at the bootom of the radiator. If you remove it a large roasting pan should hold what you have in the radiator. Dispose of properly as it is probably poisonous and will kill pets and animals. You can run a garden hose through the top of the radiator while the engine is running for a fa minute or so to get scaling and slime out. This is what is known as a radiator flush. Be careful to always have water going through the engine when running. Put plug back in bottom and refill with anti-freeze. They do make a non-toxic antifreeze which is propylene glycol based versus ethylene glycol based. They work the same but the propylene based won't kill pets shoudl they lick it off the ground and cost a little more. Hope this helps.
