What is claimed is: 1. A snowmobile, comprising: a chassis, an engine supported by the chassis, a drive track, the engine coupled to a drive train for propelling the drive track, a pair of steerable skis suspended from the chassis, and a straddle type seat supported by the chassis; a heat exchanger
What is claimed is: 1. A snowmobile, comprising: a chassis, an engine supported by the chassis, a drive track, the engine coupled to a drive train for propelling the drive track, a pair of steerable skis suspended from the chassis, and a straddle type seat supported by the chassis; a heat exchanger mounted to the chassis and including a reinforced portion, the reinforced portion positioned adjacent a chassis wall to increase the rigidity of the chassis wall, the heat exchanger containing an inner passage for carrying heat absorbing fluid, the heat exchanger having a heat exchanging outer surface for dissipating heat from fluid carried by the inner passage; and an engine mounting assembly mounting the engine to the chassis, the engine mounting assembly including a connector that connects together the engine, the reinforced portion of the heat exchanger, and the chassis wall to support the engine in place. 2. The snowmobile of claim 1, wherein the chassis includes a rear portion forming an inverted U-shaped drive tunnel, the chassis wall being generally transverse to the vehicle and mounted at the forward end of the drive tunnel to form a close-off panel. 3. The snowmobile of claim 1, wherein the chassis wall is positioned between the reinforced portion of the heat exchanger and the engine. 4. The snowmobile of claim 1, wherein the engine mounting assembly includes an engine strap connected to the engine, and the chassis wall is positioned between the reinforced portion of the heat exchanger and the engine strap. 5. The snowmobile of claim 1, wherein the connector extends through the chassis wall and into the reinforced portion of the heat exchanger. 6. The snowmobile of claim 1, wherein the reinforced portion of the heat exchanger is shaped to conform to the chassis wall to increase the rigidity of the chassis wall. 7. The snowmobile of claim 1, wherein the reinforced portion of the heat exchanger is positioned against the chassis wall to increase the rigidity of the chassis wall. 8. A snowmobile, comprising: a chassis, an engine supported by the chassis, a drive track, the engine coupled to a drive train for propelling the drive track, a pair of steerable skis suspended from the chassis, and a straddle type seat supported by the chassis; and a heat exchanger containing a sealed inner passage for carrying heat absorbing fluid, the heat exchanger having a heat exchanging outer surface for dissipating heat from fluid carried by the inner passage, the heat exchanger formed with an open-air interior cavity to increase the rigidity of the heat exchanger, the heat exchanger mounted to the chassis to increase the rigidity of the chassis. 9. The snowmobile of claim 8, wherein the heat exchanger is mounted in several locations to the chassis to increase the rigidity of the chassis. 10. The snowmobile of claim 8, wherein the heat exchanger is mounted to multiple panels that form the chassis to reinforce the multiple panels to increase the rigidity of the chassis. 11. The snowmobile of claim 8, further including an engine mounting assembly mounting the engine to the chassis, the engine mounting assembly supporting the engine and including a connector that connects to the heat exchanger to mount the engine to the chassis. 12. The snowmobile of claim 8, wherein a connector connects together an engine mounting assembly supporting the engine, the heat exchanger and the chassis to increase the rigidity of the chassis. 13. The snowmobile of claim 8, wherein the heat exchanger include stiffening ribs that extend within the open-air interior cavity to increase the rigidity of the heat exchanger. 14. An integrated engine mount and heat exchanger for a snowmobile, comprising: a heat exchanging outer surface having cooling fins for dissipating heat from within the heat exchanger, an inner passage for carrying heat absorbing fluid, a reinforced engine mount portion formed integrally with the heat exchanger and an aperture for receiving and connecting an engine mount connector. 15. The integrated engine mount and heat exchanger of claim 14, wherein the inner passage and the reinforced engine mount portion form a generally triangular shape with the inner passage forming two of the sides of the triangular shape and the reinforced engine mount portion forms the third side of the triangular shape. 16. The integrated engine mount and heat exchanger of claim 14, wherein the reinforced engine mount portion connects to the inner passage to form an open-air cavity. 17. The integrated engine mount and heat exchanger of claim 14, wherein the inner passage is sealed off from the reinforced engine mount portion. 18. The integrated engine mount and heat exchanger of claim 14, wherein the aperture is defined by a threaded portion that threadably receives the engine mount connector. 19. The integrated engine mount and heat exchanger of claim 14, further including an inlet and an outlet through which the heat absorbing fluid is circulated. 20. The integrated engine mount and heat exchanger of claim 14, wherein reinforced engine mount portion and the inner passage are formed from a single extrusion.
