Surprised there is no good picture in the factory workshop manual to show position of the flaps in the closed or open positions.
In this picture it is in the fail-safe position as if the cable or thermostat wasn't working. Just want to make sure they are correct. When hooking up the thermostat wire the flaps would both move as the little "lever" would move down. Just seems strange that in the fail-safe mode it covers up the oil cooler- you 'd think it would want air going over and through the cooler to allow the engine to run cooler if the thermostat failed...  |

It's actually not covering up the oil cooler. It is diverting air down through it. Reach behind there with your fingers and you will find about a half inch gap that diverts air to the bottom side of the flap and down through the cooler. Lift that flap and you will see that gap closes and all the air is diverted away from the cooler and over the top.

How do you set the end of the wire in the clamp? Engine cold and wire slack. Wire tight ?

I like engine warm and wire not quite taut. this way you dont have to struggle pulling the flaps down to set...and you know that the wire is long enough to let the flaps fully open. |

Wire should be tight when the engine is cold since the thermostat expands and slackens the wire.

I just did this last weekend, using my 13 year old son as an extra set of hands. He held the bar in the "fully shut" position (you can get a tiny bit of leverage at the bend) while I pulled the thermostat cable taut with a pair of pliers and tightened the nut that locks it. |

I find the easiest way is to carefully put a heat gun on the bellows, watch for it to fully expand, and then go to the top, take the slack out, and tighten up the clamp.

Since the default/Failure position is hot and the thermostat expands, I like to have cable slack in the hot position. That way you are sure the spring is holding it totally open. it is only cold for a little while. |

(IMG:style_emoticons/default/agree.gif) Rob best method,the cable should be firm not guitar string tight otherwise the bellows will be under strain and will split. I tested the tension of the cable and found even with it a bit slack the air flaps were still working as they should. Hot tip,replace the cable with a bike cable they are a larger diameter and move easier in the roller.  |
