Don't know if this helps - but Hey!! I have noticed in pictures of Mercedes for sale on Ebay that there is no Hood insulation on cars in Florida. My insulation is foam and 1" thick - could this be holding the extra heat in?? All those in Texas and elsewhere who are getting normal 85C-90C temps - do you have insulation pad under hood? Those whose temps are like mine - do you have insulation pad?? Maybeeeee????
