Abstract: A baffle for engine fluid cooling includes a fluid guide having a pair of side walls, a bottom wall, and a coolant fluid inlet. A channel receives a pair of heat exchangers such that one may be positioned proximate to or above a part of the bottom wall and the other may be positioned proximate to or above another part of the bottom wall. Some coolant entering the guide flows into the first heat exchanger and some coolant is passed under the first heat exchanger and subsequently into the second heat exchanger.
