Courtney, To the extent that combustion temperatures rise (affecting exhaust temps) as the engine temp rises, the thermostat can have an effect. If it's stuck open, and you never reach normal operating temp, the heat exchangers won't work quite as well either. I noticed a 'little' difference in my old '78 when I took out the t-stat and flaps. I never left the t-stat and flaps in any VW motor here in Phoenix, since the winters aren't that cold, and it takes about 10 minutes to destroy an air-cooled motor here in the summer if the t-stat sticks closed - or even close to closed.

My auxiliary fan mounted above the engine in the engine shroud blows great air up to the front of the van, but it is barely warm. If I drive on the freeway for 1/2 hr., it gets warmer. My thought was that the thermostat which has failed, is the culprit, but wait a minute! >The heat is produced in the heat exchangers, which blow the exhaust heated air forward, so the thermostat has nothing to do with this does it? Hmmm, I am really perplexed about this one. I wonder what else it could be? I am assuming that with the amount of air blowing out when I turn on the fan, there are no holes in the large pipe that runs under the van, or I wouldn't get such air?? >Hmmm, >Courtney > > > |
