Coolant valve possibility mentioned in above thread. Has anyone installed one?

 

It's actually "bought" in the USA- here's a little Americana from the wikipedia:

"Sold American" was written in 1938 by Glenn Miller and John Chalmers "Chummy" MacGregor, the pianist in the Glenn Miller Orchestra... The title is based on an American Tobacco Company (ATC) radio ad jingle of the 1930s for Lucky Strike cigarettes featuring a tobacco auctioneer chant delivered by North Carolina tobacco auctioneer Lee Aubrey "Speed" Riggs which ended with the phrase, "Sold, American!", stressing that American only purchased the highest quality tobacco for its cigarettes."

And I try to purchase from the highest quality suppliers - you know who you are!

 

I think it can be done, but you need the extender otherwise it will get "caught" by the side of the block before you can fully tighten it. I tried, but then I got caught by my Devek L2 headers. I think with stock exhaust, it will be fine...

 

Just bought these just now for the oil and coolant plugs. My car is up on the liftbars at the moment so it's tempting to install them when they arrive unfortunately I don't really need to do a coolant or oil change for a while.
