RaderNed Posted October 30, 2018 Share Posted October 30, 2018 My thermostat is occasionally sticking, so I'd like to replace it. Easy enough, except the bolts on the housing seem to be seized. Don't want to snap or strip them, any tips? Tried searching past threads but didn't find anything. 1985 Sunrader, 4cyl 22RE. Thanks! Quote Link to comment Share on other sites More sharing options...

jjrbus Posted October 30, 2018 Share Posted October 30, 2018 I have only read about this and not tried it, I have it securely tucked away in my memory for the next time I have an issue. For those of us without a torch set might be worth a try? http://www.loctite.com.au/3320_AUE_HTML.htm?nodeid=8802649931777 If you do try it please let us know how it works.

Interesting , if my normal penetrating oil attempts fail I'll see if I can find some of this and try it.

WME Posted October 30, 2018 Share Posted October 30, 2018 After you finally get things apart, remember to use anti seize on any bolt going into aluminum. Including sparkplugs Quote Link to comment Share on other sites More sharing options...
RaderNed Posted November 22, 2018 Author Share Posted November 22, 2018 The penetrating oil did the trick. Also, the new thermostat not only solved the sticking problem, but also brought the average operating temp down. Quote Link to comment Share on other sites More sharing options...
