Hi,
Is this the correct positioning for the cooling flaps with a cold unexpanded bellows? Somehow I think the rod may have been bent or the flaps twisted by the previous owner. I want to hook up the thermostat so I can have a wintertime heater. Thanks...Dan Attached thumbnail(s)

Mike,
On the standard temp gauge in the console in the middle, the temp gauge should be under the T in TEMP pretty much ALL the time after warmup. I have owned 6 914 4's and none of them ever went over the T on the Temp gauge, even in St. Louis, one of the hottest/most humid places on earth. That motor is running VERY hot. Change the oil, check the sensor, and replace it just for safety's sake. Many on here say that 220 is warm for oil and 240 is BAD. I believe them. On a cold motor, flap bolt tiedown should be all the way to the REAR of the motor and the flap rod will rotate FORWARD at proper temperature. CLOSED is default with wire attached firmly, and closed is the flaps rod pulled ALL THE WAY BACK, not forward. Maybe your rod is rotated so the flaps are in the wrong position on the rod? Not sure. As the thermostat bellows heats, it expands and the wire lengthens, so to speak, and opens the flaps to divert heat to the oil cooler passenger side, and out the fan exit on the drivers side. I had a wire break right after an engine rebuild and the main bearings scored and disintegrated because it ran too cold in NJ, on my first teener. Motor was toast in 1000 miles. Had to redo the bottom all over again. OUCH! Too hot and many things can go even more badly. Good luck! John |

I disagree with the "ALL the way" part. QUOTE(avidfanjpl @ May 12 2011, 07:24 PM) CLOSED is default with wire attached firmly, and closed is the flaps rod pulled ALL THE WAY BACK, not forward. ... John Yes, closed is ALL the WAY back, but if you set it closed ALL the way, it will never get to open ALL the way. (The thermostat does not have enough range to do both.) I maintain that when hot, it is more important to be completely open then it is to be completely closed when cold. YMMV in extreme cold environments of course. But summer? Make sure it's OPEN when warmed up. |
