Cooling flap system on a '74 2.0 stuck open Options

[Lockwodo]

Hi all. As I work through the maintenance issues on the '74 2.0 I bought recently, I noticed that the cooling flaps are wide open (as they would be when engine is warmed up) all the time. Since this is the default position when a thermostat fails, I'll be checking the thermostat and wire/pulley mechanism. But just wondering what priority resolving this should have? It's not like I don't have plenty of other things to take care of (IMG:style_emoticons/default/smile.gif)

The car starts from cold, idles and runs well. I live in an area where it's unlikely I'll be starting and driving the car in temperatures below 60 degrees F. What do you think?

I am a believer in hot oil, but knowing what's going on in the heads is a good idea too. You can have heat issues that you may not pick up right away. That's why I suggest leaving the flaps if you want, determine if the engine is running right first although fixing the flaps will make you feel good and it is an easy job.

Others may have better advice on the heat gun but I had a very hard time finding a good spot to get meaningful information. So many shields and the only openings you can really get to are near the exhaust in my attempts. Best option for the actual temp that matters (head temp) is a simple head temp gauge. Well worth it and not expensive.
