Overheated. Why won't it start?


I'm not really familiar with JEEP mechanics but if you've replaced your water pump and it's still overheating with full water/coolant level, you should check the thermostat; when it fails, it's a common cause or overheating in all kind of cars

Why the water not circulating throw radiator


If your water is not circulating you can only have one of two problems. Either your thermostat is stuck shut and needs to be replaced or your water pump has gone out and needs to be replaced. I would start with the thermostat because it is cheaper and easier to get to. I hope this helps you out and if you have any more questions please feel free to ask.

How do i know if the water pump is not pumping it started yesterday getting cold air should i replace the thermostat or is it the water pump thanks


FIRST OFF TO CHECK THE WATER PUMP YOU WOULD HAVE TO LOOK TO SEE IF THE PUMP IS LEAKING EXTERNALLY IF NOT TAKE THE BELT OFF AND SEE IF THE PULLEY IS LOOSE IF NOT THE THERMOSTAT MIGHT NEED TO BE REPLACED. CHEAP WAY IS TO REPLACE THE THERMOSTAT FIRST.

How to install thermostat


The best thing to do is to buy a Haynes or Chilton manual for your vehicle.

Purchase the replacement thermostat and gasket (no they do not come as a set.)
Items needed: socket and ratchet, a tube of liquid gasket, a wire brush, screwdriver for hose clamp

Open the hood, disconnect the Neg terminal of the battery (not the red one)
The radiator accept hot water at the top and feeds it to the water pump on the bottom.
Most thermostats are located on the engine block at the other end of the water hose going to the top of the radiator.
Trace it back, and remove the hose clamp.
Pull the hose clamp back (you do not need to take it off)
Pull the hose off the thermostat hosing neck.
The housing will be held on by 2 or 3 bolts, remove the bolts to remove the housing
BEWARE OF THE ORIENTATION OF THE .THERMOSTAT
The thermostat should come loose.
There will be gasket material stuck to the housing and the engine block, it must be scraped off before installing the new gasket.
Compare old thermostat with new one. Make sure they match.
A good tip is to stress the new thermostat in boiling water to insure it works. Boils some water, and place the thermostat in the water and watch it open. pour out the water, run it under cold water to cool it off.
After using a wire brush to remove the old gasket material,
place liquid gasket along the edge of the engine block opening and place the new gasket on the opening.'
Place the new thermostat in place (IT MUST GO IN ONE WAY)
Place the housing back on the engine block and replace the bolts, (tighten the bolts gradually )
replace the hose on the neck, and replace the clamp and tighten.
remove all tools and reconnect the battery

Good luck and don't forget to vote.

What should be the thermostat temperature for a car in Edmonton, Canada, Where the temperature varies from +30 to -35?


Your thermostat should not remain closed if the water temperature is above 85. The best way to find out if the thermostat needs replacing is to remove it (when the engine is cool), place it in a pot of water with a candy thermometer, and boil the water. You will see the thermostat open at some point. If it opens before 80-85, replace the thermostat.
