Does anyone have detailed instruction on how to do a complete flush & fill on a 05 Coupe, I'm not looking to just dump coolant from the radiator and refill. I've found in the service manual that there are two caps on on the front of the engine block but no detailed instructions. I am trying to upload the pdf of the manual but it will not upload. Any help is greatly appreciated :confused:

Quite simple actually :)

1) Remove the drain plug from the bottom of the radiator and drain the coolant.
2) Fill up the radiator with some sort of radiator cleaner and fill up to max with DISTILLED water.
3) Turn the car on, let it run until its warm, then turn on the heater at max. Let it run for 15-20 minutes
4) LET THE CAR COOL COMPELTELY.
5) Drain from the plug again, also remove the thermostat and let the rest drain from there. Put the thermostat back on.
6) Fill with distilled water to the top, run for 10 minutes after it warms up let it cool, and then drain again from the drain + thermostat
7) Replace the ring in the thermostat, reattach it.
8) Fill with: 1 gallon of 50/50 coolant mix, 2 gallons of water, and one bottle of water wetter (its summer now... unless you live in somewhere that gets really cold.

Turn on the car, let it run a bit to mix it all up.

Success :)

Thanks for the steps. What brand of radiator fluid is recommended? Anyone know what the factory recommends or what the dealers are using?

Any fluid will work... I suggest (as long as it is summer and you dont ever hit freezing temps):

15% antifreeze, one bottle water wetter, rest distilled water.

In a Coupe, Spyder, Gransport, that is:

1/2 gallon of coolant, 2 1/2 gallons of distilled water, one bottle of WW.

:)

Makes your engine run the coolest and most efficient possible... without the risk of freezing, etc.

You do realize that March is not even close to being Summer?
(it snowed yesterday)

For those of of that live in the real world, a 50/50 mix of Anti Freeze and water is a better idea.

Fred, I meant "summer" not summer. Relatively speaking, in a nice chunk of the world it is now hot enough to turn on the AC in the house.

If you experience a lot of snow, use 50/50, otherwise, less is more.
