Your 'logic' regarding how a 'bypass' cooling system woks is faulty. The thermostat in a 'bypass' cooling system actually CUTS OFF the flow thru the engine to force the flow thru the radiator.
NO THERMOSTSAT = NO COOLING
This is because all the coolant is likely to 'bypass' the radiator and overheat the engine.
To more specifically answer your question... The upper hose (small diamator) which is plugged into the top of the plastic pressure-canistor should ALWAYS be 'peeing' antifreeze into the top of the tank. (even at idle)
Since you describe not having any 'pressure' in the upper radiator hose, this tells me that you have a lot of air in the system. It is possible you simply have too much air in the cooling-system. Even a good waterpump cannot pump air.
Once the engine is at temparture (with cap on pressure-resivour) the upper radiator hose should be too solid too squeeze at all. If you even loosend the cap.... all pressure will be lost from the system.
Also, this cannot be said enough times... USE ONLY "G12" ANTIFREEZE IN VW ENGINE. (pink color) It clearly says "G12" on the side of the pressure-resivour.
Mixing in even a slight amount of the 'green' type of antifreeze can cause 'gelling' and can plug up passageways inside the engine. (No coolant flow at all)

My gf's VW Beetle won't shift into reverse. When we parked it reverse worked fine. Went back a short time later and it wouldn't shift into reverse. Any ideas? Anyone know where I can get a diagram of the tranny so i can fix this p.o.s.?
#1102 of 1143 Trunk light malfunction

I have a 2001 turbo beetle, and i'm wondering if anyone has this problem. My trunk light is intermittant. I've changed lights and checked for a short but can't find anything. any ideas anyone?

Perhaps the switch that turns the light on when you open the trunk is sticking at random. Since you changed the bulb and the wiring seems to be OK, that's the next thing I'd look at. I had a dome light that was not coming on randomly and it was simply the switch in the door frame being gunked up and sticking a bit.

where exactly is the switch located? i've looked but can't find it. Thanks for the help!

I beleive the switch is in the latch... just like the passenger-doors have all the switches for the alarm-system and interiour lights. (In-fact, the Hood and Trunk are part of the alarm-system too!)

Do you mean UNDERNEATH the vehicle? This could be the AC condenser drain or the sunroof drain. Both of these should be considerd normal for any car.

It is underneath my car the water drops from the bottom middle location. Thanks.
