This Jayrad JR8532HD radiator slots into Mitsubishi Fuso Rosa KK-BG64EG buses running 4M51, 4D36 or 4D33 engines, with a core footprint of 440 mm high by 610 mm wide for steady cooling on hot town runs. The 48 mm core depth helps the bus handle long climbs and slow school routes without temp spikes, and the matched 47 mm inlet and outlet line up with standard hoses so workshop swaps stay straightforward.

The integrated transmission cooler inside the 48 mm thick core keeps auto gearbox temps in check when the bus sits loaded in 40°C traffic or crawls through hilly streets. Jayrad builds the JR8532HD to suit the KK-BG64EG mounting pattern so brackets and shrouds stay put, which is a smart buy for operators wanting predictable fit and less mucking around. This spec is geared for Australian fleets that need cooling gear made to work every day.

Q: Does this radiator include an integrated transmission cooler?

Yes, this JR8532HD radiator includes an integrated transmission cooler. The cooler sits inside the main core and shares the same 440 x 610 x 48 mm body. It connects to the vehicle’s transmission lines using the factory-style ports. This helps manage gearbox temperatures under load without needing a separate external cooler.

Q: What engine codes does this radiator suit in the Rosa bus?

This radiator suits Mitsubishi Fuso Rosa KK-BG64EG buses with 4M51, 4D36 and 4D33 diesel engines. These engines share the same basic cooling layout and hose sizes. The 47 mm inlet and 47 mm outlet match the factory pipework used across these codes. Always confirm your chassis code and engine plate before ordering to avoid downtime.

Q: Do I need to modify the original mounting points to fit this radiator?

No, this radiator is built to match the OEM-style mounting layout for the KK-BG64EG Rosa. The overall core height of 440 mm and width of 610 mm line up with the existing frame and shroud. Using the factory mounts keeps the fan shroud positioned correctly. A mechanic should still check for prior body or chassis repairs that may affect alignment.

Q: Is this radiator suitable for constant stop-start operation like school or shuttle work?

Yes, this radiator specification is well suited to stop-start bus work. The 48 mm core thickness gives enough coolant volume and surface area for long idle periods. The integrated transmission cooler also helps when the auto stays in low gears around town. Regular coolant changes and system checks are still important for fleets that run every weekday.
