So I finally decided to bite the bullet and replace my thermostat. Some symptoms of a bad thermostat are: Car taking too long to heat up, Car randomly getting to hot and then cooling off rapidly, Car over heating. So if you have one of these problems your thermostat might be bad so, it's time to replace it.

Tools Required10mm wrench10mm socket and ratchet with extensionsPan to catch radiator fluidsomething to pry withand a friend to help out.
MaterialsNew Thermostat ~10-15 dollarsGasket ~1 dollarRadiator Coolant ~10 dollars
Step one:Locate your thermostat. On a ka24de it's inside of the lower coolant neck. to find this trace your lower radiator hose up to the block and find something that looks like this.
Step two:Get your pan and place it under your car to catch any fluid that comes out.
Step three:I found it necessary to remove the fan to get access to the bolts better. You may not need to do this but anyways undo the 4 ten mm nuts holding it and move it out of the way.
Step four:Undo the 3 ten mm bolts holding the coolant neck to the block. With a gentle tug it should move out of the way and look like this.
Step five:Get your prying tool and take out the old thermostat, mine looked like this.
Step six:Fluid will begin to come out pretty quickly so, carefully remove all of the old sealer. Mine was blue and I peeled it off with my finger.
Step seven:Slide the new thermostat into place and it'll look like this.
Step eight:Slide the gasket in and then care fully line up the holes. I gently threaded each bolt in like a half turn.
Step nine:Tighten up each bolt as equally as possible, be careful to not over tighten.
Step ten: Remove all the stuff from under the car that you had catching the fluid and reattach the fan the same way you took it off.
Step eleven:Locate and loosen the bleeder bolt. Start the car and run at idle with the heat on a full blast until coolant come out of this hole. Be careful to add coolant the whole time though.
Step twelve:Top everything and clean up!! your done!! On the first test drive I would make sure to go slow to ensure that the thermostat opens correctly.
