WIBIMMERS

I have a brand new never installed Berlin TQR 07 headunit and a PSA108 amplifier, both are in excellent condition and everything is included, it even still has the original "code" anti-theft stickers for the windows! If you are looking for something period correct for your 80's BMW, you cant really get any better than this one, and it comes with an accessory jack so you can run other amps off the DIN plugs from the receiver.  Looking for $300, as it is a 100% complete setup and in perfect condition.  Can ship, on your dime. or arrange local pickup, I am in Racine. message me or email at: [email protected] [image: UXClqcr.jpg] [image: u6UzDCo.jpg]

Is that on the outlet passage from the engine?  The purpose of the fan is to be sure that the coolant supplied to the engine from the cold side of the radiator is below the switch setpoint.  The main purpose to change that system is to put a lower temperature switch in when removing the mechanical fan.  For example most e36 models come with a 91/99C switch for low/high speed.  I have installed the factory 80/88C switch when removing the mechanical fan.  Then the fan will activate when the coolant supply to the engine climbs to 80C (176F) and will ramp up to high speed when coolant reaches 88C (190F).  That is plenty adequate to cool the engine.  If you supply colder coolant it just causes the thermostat to be farther closed to restrict the flow so no more cooling is achieved.  With the temp switch there you are measuring the coolant temp coming out of the engine which will always be the same (thermostat temperature)  So there is no way to know if the coolant returning to the engine is cool enough to provide adequate cooling.  The only thing it does is run the fan excessively depending on the combination of thermostat and fan switch temperature. Not trying to rain on your parade, just sharing what I have learned about these cooling systems.

I am a new resident in Wisconsin, well less than a year, but still new.  Looking forward to meeting some new friends whilst here, also love to buy and trade good parts or help a fellow Bimmerphile out if they are in need. Just thought I would introduce myself. OH! and to a fellow named Dan who has a very clean white E30 we were cruising down A in Kensoha county that one day, I thank you for recommending me to this site! Eager to bring the old girl out of hibernation when all the salt is clear. Hey 6inasrow! Welcome! Waiting on that warm weather to get out for a cruise!
