I recently installed a Frostheater(FH) on my MK4 ALH TDi.
The install was quick, easy and painless. I lost MAYBE half a gallon of G12(being extremely cautious and mindful)
After the install, I topped off the coolant(slightly over Max) and drove around for nearly 50 miles, without shutting down. FH Suggests 30 miles before testing the heater. Naturally the system used some to fill air gaps maybe and I am now right below MAX, perfect.
So, I "tested" it this morning. Plugged it in, checked to make sure it wasn't smoking or starting a fire.. Checked acouple more times, then, i didn't come back for nearly 4 hours. after 4 hours I unplugged my FH, Popped my hood and boy was it WARM!(nearly HOT, or very WARM) Valve cover, coolant hoses, everything up top was nice and toasty @ 40° outside. COOL!!!!!
now to the question:
**The FH unit was making an almost boiling sound, or maybe hissing**
*Is that normal, have any of you users noticed that noise?
**How can I make sure my coolant is circulating properly to avoid frying my new FH?
I love the idea of having it, even for chilly mornings! and I want to make sure it functions properly. I figured id ask some hands on users, as opposed to emailing FH about a simple question. I'll Email them if you guys dont have any similar experiences. Thanks!
Cleaned up the plug in with a Marinco 150BBIW
