As it's been getting colder, I'm noticing that my engine isn't warming up like it used to, and I wonder if there might be something else going on.
The temp gauge used to sit just above 175 when I got my car a couple of months ago, maybe 180 or 185. It has been getting colder, but not that much colder, and now unless I'm driving on the highway, it tops out at maybe 160.
A possibly-relevant modification I've made is to bypass the ACC servo 'cause it was leaking, but I can't imagine that cabin heat itself would be enough to keep the engine that much cooler.
Could this mean that I need a new thermostat, or is there something else I should look for? I remember reading that the engine should run at least 175 degrees in normal operation, for proper combustion, so I'd really like to take care of this.
thanks,
-tom!
