Hey fellas,

I have a question on the manifold heat control valve. After the engine gets to full operating temp, does the valve stay fully open or does it open and close to maintain manifold temp in cold weather conditions?


Thanks.

It usually stays full-open once the exhaust manifold is up to temp.

Thanks Doc.
I thought so but wanted to be sure.
