Re: engine running hotter than normal
Stop trying to believe the stock gauge means anything. Install a mechanical (or electric) gauge of your choosing. Then you'll be able to post back here with useful info, like "My Bronco was previously running at around 190-195 water temp when outside temps were around 55. Now, at the same outside temps under similar driving conditions, my water temp sits around 215. At idle it sometimes nears 225."
Doesn't this sound better than "M" and "R?" It does to me.
My guess is that you'll find nothing is wrong w/your cooling system, but you need some meaningful values to reference first.
Autozone sells some cheap mechanical Sunpro gauges for about $15. They're a bit bling-bling but are white-faced and nice for what they are IMO. I've had one in my van (beater) for about two months now, and I believe it is relatively accurate. I can tell you my van idles at 190 all day long and runs at 190-195 on the hiway. I can see the needle fall rapidly when the t-stat opens, and I can see the temp spike when you shut it off (normal for all motors). Very useful and informative. [img]images/graemlins/burnout.gif[/img]
