Hello I bought a eccentric shaft thermostat replacement plug from mazdatrix and I have a question to ask before installation. I want to know if I use the spring from the old thermostat or do I just use the replacement plug as is and throw away the spring?
Here's a pictures of the plug: http://mazdatrix.com/b4.htm : just scroll down until you see "Eccentric Shaft Thermostats, Springs and Replacement Plugs" as the heading, and it is the 3rd picture in the box. THanks

 

You still use the spring! it puts the tention on the plug to keep the pressure to the plug.. Send me an email and I will send ya a word document with the instructions.................

Would it be a good idea to replace the rubber gasket on the E-shaft bolt or not when doing all this?

 

I didn't replace the gasket and no leaks spotted in over 2 years, or at least from that particular item .
