This is my first post so be kind. We had a couple of warm days in the upper 40's so I thought it would be a good time to install a block heater and a cab heater in my GC1705. I get the block heater installed and started on the cab heater. I decided to use the thermostat bypass for the connections so I would get heat quicker than if I connected to the heater hoses. I connected the inlet for the heater to the thermostat side. I thought the hose was 3/8 but it's 5/16 so now I'm not sure if I will get enough coolant flow to make heat! So I checked all the connections and start filling up the radiator and that is when I see the block heater is leaking. So I drain the coolant again, remove the block heater, and that is when I see a piece of o-ring missing. I don't know if the piece is in the block or if it came out with the heater but I haven't found it. After a few minutes of screaming, I head to the parts store for a new o-ring. I get everything installed and coolant filled so I fire her up and check for leaks. After 5 minutes or so I start to get a little heat. I let it idle for about 30 minutes while I added coolant (radiator cap off) and checked for leaks. I didn't see any rubber chunks in the radiator so I'm still not sure where that piece went. The coolant gauge stays at the first mark and I have a bit more heat. It isn't exactly hot, but it is much warmer.
So here are my questions.
1: if the O-ring is in the the engine will it cause any issues?
2: is the heater connected correctly-thermostat side to inlet?
