as a retired GM mechanic of 40 yrs.i drive Nissans .,when i started at the GM dealer in 78 i had a 69 Datson with a 283-powerglide. in early 80s they got a Diesal Datson on trade. i bought that .in the next 40 yrs i bought about 15 more from them. never a Chev.till a 99 in 2006. have bought and sold a dozen or so D21s. there great to work on. Dont reply on dealer to fix your Nissan..learn to do it yourself.

Check the "hot air pickup control" thing in this thread.
The hot air tube stuff doesn't do squat. Might help you warm up a little quicker but that's it. Been running without mine for years and in sub zero temps.
