Almost forgot, the Yanky 88's definitely open at 88 as I watch like an eagle the temp gauge. My thermo fans are currently set at around 1st @ 92 and 2nd around 99. Basically once they open at 88 now and I'm not hauling on flat ground the thermos aint kicking on especially over Vic winter days.

Interesting Mark, show an external neg pressure zone I am guessing, which should suck heat from the engine bay?

Reckon I'll still give the cheapo Saas reverse scoops a go somewhere in the middle of the bonnet low pressure zone. My NA truck finally goes up to Mansfield later this week for a free flowing new Millweld bar with built in oil coolers far left and far right and I'll piss off the last flexy top radiator hose too thanks Kimbo :-)
Rainsey mate, in regards thermostats, I researched heavily the yank sites from posters in the snow and desert regions, consensus seemed to be the ACDelco 88DCelsius for best all year round. About $40Aud each from Autobarn-USA online.
Mark, do you have a part number or is your description enough to ensure I get the right one? I have aleady purchased a range of spares from BD, including the thermostat, but won't hold back on getting something better.

I'm hoping mate, although I do want to keep mine more central as to not drag the hot air past the batteries each side of the truck.

I think my truck runs cool due to good air flow my front bar is very open and offers no restriction to air flow also I got rid of the flex radiator hoses that BD fit and used silicone hoses and Aly pipes
Kimbo, interested in getting a set of smooth bore silicone hoses also for my na chev. Where did you get yours and are they a straight hose in their relaxed state or pre moulded to the shape? I have removed my 9" driving lights from the grill and replaced them with light bars on BB and on roof rack, so max airflow also. As yet have not really had time to experience the issues with heat as only 800 klm on clock for new conversion, but working on it!
