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.

1. A baffle for engine fluid cooling, comprising: a fluid coolant guide having a pair of side walls, a bottom wall, a coolant fluid inlet end and a coolant fluid outlet end disposed substantially opposite the coolant fluid inlet end;wherein the bottom wall includes a first portion with a first elevation extending from the fluid inlet end, a second portion distal from the fluid inlet end and having a second elevation and a transition portion disposed between the first and second portions;wherein the first elevation is lower than the second elevation, and the transition portion provides a transition from the first elevation to the second elevation; andwherein the side walls and bottom wall provide, at least in part, a channel adapted to receive at least a first engine fluid cooling heat exchanger and a second engine fluid cooling heat exchanger therein so that the first heat exchanger is positioned proximate at least a part of the first portion of the bottom wall and so that the second heat exchanger is positioned proximate at least a part of the second portion of the bottom wall. 2. The baffle of claim 1, wherein the channel is adapted to receive at least the first and the second heat exchangers therein so that the entire first heat exchanger is positioned above the first portion of the bottom wall and so that the entire second heat exchanger is positioned above the second portion of the bottom wall. 3. The baffle of claim 1, wherein the transition portion of the bottom wall includes a ramp extending from the first portion to the second portion of the bottom wall. 4. The baffle of claim 1, wherein the coolant fluid inlet end and the coolant fluid outlet end are open ends. 5. An engine fluid cooling assembly for an engine comprising: a fluid coolant guide including a pair of side walls and a bottom wall, a coolant fluid inlet end and a coolant fluid outlet end, the bottom wall of the fluid coolant guide having a first portion with a first elevation extending from the coolant fluid inlet end, a second portion with a second elevation distal from the coolant fluid inlet end and a transition portion between the first and second portions; anda first engine fluid cooling heat exchanger and a second engine fluid cooling heat exchanger positioned within a fluid coolant channel formed by the side walls and bottom wall of the fluid coolant guide, the first heat exchanger being positioned proximate to at least a part of the first portion of the bottom wall, the second heat exchanger being positioned proximate to at least a part of the second portion of the bottom wall, and the first and second heat exchangers including engine fluid flow paths routed therethrough. 6. The engine fluid cooling assembly of claim 5, further comprising a cover mounted to the side walls of the fluid coolant guide and disposed over the fluid coolant channel, wherein the first and second heat exchangers are mounted to the cover. 7. The engine fluid cooling assembly of claim 6, wherein the cover includes engine fluid flow paths respectively in fluid communication with the engine fluid flow paths of the first and second heat exchangers. 8. The engine fluid cooling assembly of claim 5, wherein the first portion of the bottom wall of the fluid coolant guide extends along the length of the first heat exchanger and the second portion of the bottom wall of the fluid coolant guide extends along the length of the second heat exchanger. 9. The engine fluid cooling assembly of claim 5, wherein the transition portion of the bottom wall of the fluid coolant guide includes a ramp extending from the first portion to the second portion of the bottom wall of the fluid coolant guide. 10. The engine fluid cooling assembly of claim 5, wherein the coolant fluid inlet end and the coolant fluid outlet end of the fluid coolant guide are open ends. 11. The engine fluid cooling assembly of claim 5, wherein: the engine fluid cooling assembly is adapted to cool engine oil; andthe first coolant fluid inlet end of the fluid coolant guide is adapted to be supplied with engine coolant. 12. A method for distributing coolant fluid to at least a pair of first and second engine fluid cooling heat exchangers arranged in series in an engine fluid cooling assembly, the first heat exchanger positioned proximate to a fluid coolant inlet of the motor engine fluid cooling assembly and the second heat exchanger positioned distal from the fluid coolant inlet, the method comprising: passing a first portion of fluid coolant entering the fluid cooling assembly into the first heat exchanger and a second portion of the fluid coolant entering the fluid cooling assembly by at least one of around, under and in proximity to the first heat exchanger; andpassing the second portion of the fluid coolant into the second heat exchanger after the second portion of the fluid coolant passes by at least one of around, under and in proximity to the first heat exchanger. 13. The method of claim 12, wherein: the step of passing the second portion of the fluid coolant entering the fluid cooling assembly by at least one of around, under and in proximity to the first heat exchanger involves a step of passing the second portion of the fluid coolant entering the fluid cooling assembly under the first heat exchanger; andthe step of passing the second portion of the fluid coolant into the second heat exchanger involves a step of passing the second portion of the fluid coolant up into the second heat exchanger. 14. The method of claim 13, further comprising: exiting the first portion of the fluid coolant through outlet openings located between the first and second heat exchangers. 15. The method of claim 13, where each of the passing steps are performed, at least in part, by a baffle having a larger cross-sectional area in a region corresponding to the first heat exchanger than in another region corresponding to the second heat exchanger, and having a ramp extending between the first and second heat exchangers. 16. The method of claim 12, wherein each of the first and second portions of the fluid coolant individually amounts to less than 100% of the total fluid coolant entering the fluid coolant inlet.
