I know this is a small update but I have finished up the coolant lines and frost heater install. Nothing too difficult here, just need to undo my heater core bypass and put it together the right way. I had intended to run the Ranger vacuum operated bypass valve as well as the TDI coolant glow plugs but I simply don't have enough room to get it all in the space avaiable. Keep It Simple Stupid! I'll likely need to install a bleeder valve on the heater core outlet but for the time being I'm going to slip the hose off the barb B5-Passat style.
Now I need to fab up a bracket to hold the frostheater in place, connect up my radiator lines and fill it with water (need to flush out the green stuff before I put G12 in there).
I have a question for you guys: As you can see I've removed my heater core bypass due to space limitations (I've also had to leave out my coolant glow plugs due to space
) and am wondering what effect this will have on heating/cooling performance? Does the HVAC plenum have a bypass door that bypasses the heater core when you turn on the A/C? If it is absolutely necessary I can plumb it back in but the way it ended up was so very simple and I'd hate to have a rats nest of there.
