have used rear doors open partially on my MCI 8 which helped. also misters(wouldn't recommend for long run) as they tend to damage radiator with extended use. New radiators finally solved my problem.  Bob

Instead of closed scoops, would some sort of spoiler that directed air in be better?

Hmmm, I have thought about adding a 3/8" or 1/2" wickerbill to the front edge of the radiator opening?   Jack

This discussion always intrigues me --- when was the last time you had heat problems at speed (ie over 55 mph) --- Even when my 8V71 was just about toast it would always run cool enough if we were rolling down the road but when I hit a hill and slowed down THEN I would need more cooling --- Everyone says the scoops don't work at speed BUT DO help when you are going more slowly  --- so what to do what to do --- the misters are ALWAYS an interesting topic too --- do misters cool with water running off the rads or do they cool by evaporation???

I ALWAY like to hear (should that be read) the opinions and ideas for this --- not a problem for me with the L10 but entertaining to see what people think

My 5C came with the scoops. 6V92/HT740, 90 injectors. It does get hot going uphill on a hot summer day. I took the scoops off, and there is NO difference. Plus it looks better without them, IMO. On my to do list is a transmission cooler.

Of course, we have been leaving out another standard, which is the full length mud flap going across behind the wheels.

  It seems I read something like that once before, like on old SAAB's or something. Are you suggesting a full flap ahead of the engine would act as an air dam? That it would create more low pressure aiding air flow through the rads?

Yes, as I understand it, it was standard practice with GMC's.

Any more info on the mudflaps? That sounds interesting!
Misters are only needed on a steep climb, so they are rarely used enough to clog up the radiator. We installed some on a DL3 and they work well and are only needed on a hot climb.

Just try and use soft water in those misters. Regular water can lime it up and compound your problems in time.
