A heat exchanger is provided for dissipating heat from a dual turbocharged engine. The heat exchanger has a jacket water cooler, and first and second charge air coolers. The three coolers are arranged in parallel enabling each to operate with a maximum temperature differential, and have fronts that lie in parallel planes. Charge air from a first turbocharger is directly piped to the first charge air cooler, and charge air from the second turbocharger is directly piped to the second charge air cooler. A first baffle is between and upstream of the first charge air cooler and the jacket water cooler. A second baffle is between and upstream of the second charge air cooler and the jacket water cooler. The baffles can direct selected amounts of air to each of the three coolers and prevent radial convective scrubbing. A fuel oil cooler can also be provided.

A system for mounting a side frame to a heat exchanger is provided in which the heat exchanger has a header plate and the side frame, a radial extending flange that lies parallel and adjacent to the header with aligned openings in the header and side frame flange. For each of the aligned openings, a spacer that is used has a tubular portion at one end and an enlarged diameter flange at the other. A bolt extends through the aligned openings and through the spacer. A nut on the bolt secures the spacer to the header. A tubular elastomeric washer is received on the spacer tubular portion and is compressed between the spacer radial flange and the side flange. Changes in length of the heat exchanger are permitted without changing the length of the side frame by compression of the elastomeric washer.
