Getting ready to install a Zerostart 8000 on my '05 PD jetta. Question: why does the check valve need to be removed from the heater?
Thank you in anticipation.

The check valve works to make sure the coolant flows in one direction when it is heating. Where we place the heaters on these cars coolant flows in the opposite direction when the engine is running...So it can't have a check valve.

The issue is the coolant moves via convection since there is no pump in the zerostart. So if you reverse the two hoses the heated coolant will still be trying to move in the same direction.That's what I've been reading. But, what I don't understand is why the two hoses can't just be reversed so the heater is moving the coolant in the same direction as it naturally moves...Is that a dumb question? Where do the two hoses going into the oil cooler go? If I reversed the hoses, would it try and move the coolant against the thermostat instead of into the engine?? I don't get it...

http://www.frostheater.com/frostheater.htmDoes the frost heater have a checkball which requires removal before installation? Thinking of getting one.
With my FrostHeater, my instructions said to just remove the old lines and in with theirs. But that's for a MKIV ALH.I would check with frostheater but my guess is that if you buy their kit you would just put it on.
