Coolant Temps are perfectly fine. I use a stock genuine thermostat.hey dac69er...i've just noticed you are running the stock radiator.
based on my past experience with td04l/vf series upgrades, the stock automatic (2 core) and stock manual (single core) radiators don't cool very efficiently with prolonged spirited driving...may be my relatively high daily temps (30c) contributed to that and with your cooler region you may be ok
but out of caution, i'd suggest you upgrade to the 3 core civic radiator
