How to completely flush the coolant system:
>Start with a cool engine, and remove the coolant overflow bottle under the battery to completely flush it out. I sprayed a degreaser into it and let it sit for about an hour to get rid of the brown muck.
1-Drain the radiator. There is a black plastic screw at the bottom of it, passenger side. You can remove it all the way, but it will drain just fine by unscrewing it halfway too.
2-Remove the upper radiator hose to get to the thermostat. Remove the thermostat and re-install the hose to the engine. This helps flush the engine's coolant faster.
3-Fill the radiator with water, leave radiator cap off, and start engine for about 10-20 seconds, then turn off. This allows the remaining coolant inside of the engine circulate into the radiator.
4-Drain radiator again, and repeat step #3 several times to completely flush the system. It may take a good 4-7 times to get all of the coolant flushed out.
5-After you get all of the coolant flushed, make sure the radiator is fully drained, leave the drain plug open and start the engine for approximately 5-10 seconds to get some of the coolant out of the engine for the last time. TURN ENGINE OFF!!
6-Tighten the radiator drain plug, fill radiator with new coolant, re-install new thermostat with gasket and rubber seal, cap the radiator, re-install the coolant overflow bottle & fill with coolant to the "cold" position, start engine for approximately 5 minutes. Make sure it reaches operating temperature and stays there for a few minutes, then turn off and wait 10 minutes to cool down.
7-Re-check the radiator coolant level under the cap by slowly removing it, and check the coolant level in the bottle...top off if needed. Also, check for leaks around the thermostat and radiator drain plug.
NOTE; This is not a hard procedure, just time consuming. I tried to explain it as easy as possible. If I've missed any details, please point them out. Farewell Dex-Cool!
