I just recently purchased a my first 914 2.0, and I want to get the car up to date on its maintenance. First on the list is all fluid changes including new brake lines. Also I am not too familiar with these air cooled engines.
My question is, can I remove the thermostat and manually keep the engine cooling flapper open permanentl? I live in Orlando, Fl and its always hot or mild. I just want the engine to run as cool as it can. Is this ok to do? |

this comes up every-now-and-then, honestly if you take the thermostat off, the flaps stay fully open....now i *think* that eliminating the thermostat might cause problems with the oil cooler or something...somebody else knows the answer, I'm just tryin to recall what i heard

I see that your from Bowling Green, Ky.... I lived in Clarksville, TN for 10 years which is on the state border. My car was actually from Louisville, Ky and the mechanic shop the PO used was called "AUTOMOTION". (IMG:http://www.914world.com/bbs2/html/emoticons/smile.gif)

In Orlando, yes, you can probably safely leave the thermostat off. It wouldn't hurt to have it on though. Using it won't make your engine run any hotter, it just lets it warm up faster. The less warm-up time the better, since that is when most cylinder wear happens. And BTW the thermostat flaps only block the air to the cylinders and heads while warming up. The oil cooler always gets full airflow. |

Just remember to leave the flappers in there.
No thermostat = OK. No flappers = NOT OK. THE DAPPO yanked the flappers on mine so it would "run cooler". Great, now I don't have any air being directed through the cooler, it just dumps out the bottom. My semi-fix was to put a switch-driven fan on my remote oil cooler. A-1-SUPARS now. |

Ok, I am confused....When the thermostat is hot it should open up the flappers thus letting in cool air, right? So if I take off the thermostat, since the flapper is spring loaded, it will always stay closed unless I manually keep it open, right?
Basicly, is the flapper normally closed or open with the spring tension? |

Cold and hot to the human body is not the same as cold and hot to an engine.
When I lived in Florida, I never saw outside air temps near 180 to 200 degrees, which is the desired operating temp range for your engine oil. Your engine still sees a "cold" environment, even on a hot and sweaty summer Orlando day. The faster you get the engine up to temp, the less wear you will incur. It is best to leave the thermostat in place and functioning. |

no if the thermostat breaks or is removed the flaps stay FULLY open....but if you have a working thermostat, leave it in there.....even mark@automotion will tell you that....

My only concern is a malfunctioning thermostat, causing even worse damage because of overheating and high head temperatures. I guess it was put there for a reason.
Anyone know where to find one for a good price new? I am just going to replace it, for the ease of my mind... (IMG:http://www.914world.com/bbs2/html/emoticons/wacko.gif) Thanks |

Good thought. But, I have thrown out a lot of bad thermostats - every one has failed with the bellows expanded (cooling open). |

well problem they are NLA (no longer avalable), so take out your haynes manual, and find out how to test your thermostat....it's supposed to be 1.28908070709709 inches longer or something(its in the manual) when stuck in boiling water for x minutes...

if you keep revs around 2-3k on long routes, you'll be golden.....automotion does fine work, mark knows his stuff...get a CHT meter with the spark plug ring sensor and put it on the #3 plug....that is if you really are truly concerned....

As far as I know, the thermostats are aneroid bellows and when they develop a leak they end up fully expanded so your flaps are always open. Andrew |

I don't know, that doesn't make any sense... Since the thermostat is heat operated, thus it expands as the engine gets hotter. Doesn't the thermostat pull on the flapper downward when it expands and gets hot allowing air in? That would mean its normally closed because theres a spring tension there, and the thermostat opens it up....
Unless when the thermostat gets hot, it allows for more slack or movement to the cable and allowing the spring tension to keep it open. Meaning when the engine is cold, the thermostat is keeping the flapper closed against the forces of the spring... right? |
