This Koyorad radiator suits Toyota RAV4 ACA20/21/22/23R from 2000 to 2005 and is set up with a core height of 375 mm for standard front coverage. The 738 mm core width and 25 mm thickness keep coolant moving across the face without crowding the fan shroud. A 34 mm inlet and 34 mm outlet let you hook it straight to factory hoses when you are getting the wagon ready to tackle another trip.

The core runs a 375 mm by 738 mm finned section that sheds heat consistently in slow traffic or on hot gravel roads. Tanks and mounts line up with factory points so the 25 mm thick assembly sits square in the support panel. An integrated transmission cooler sized for this RAV4 layout helps hold fluid temperature when you get out there with a loaded trailer or roof basket.

Q: Does this radiator suit automatic Toyota RAV4 models?

This radiator includes a transmission cooler suitable for the listed Toyota RAV4 ACA20–23R models. The integrated cooler connects to the transmission lines that run through the lower tank. Always confirm your existing radiator also uses transmission cooler fittings before ordering. If your current setup has no cooler ports you may need a different unit.

Q: What years of Toyota RAV4 will this radiator fit?

This radiator suits Toyota RAV4 ACA20R, ACA21R, ACA22R and ACA23R from 2000 to 2005. These models share similar front-end dimensions and hose layouts. Checking your build plate to confirm the ACA code helps avoid mismatch. Measuring your current core height and width is a good final check.

Q: Do I need new hoses to install this radiator?

The radiator uses 34 mm inlet and outlet diameters that match factory hoses in good condition. Many owners fit new hoses at the same time to freshen the whole cooling loop. A hose that has gone hard or swollen can leak under pressure. Replacing clamps during the job is also common.

Q: Is the transmission cooler separate from the main coolant circuit?

The integrated transmission cooler sits inside the radiator tank but uses separate fluid passages. Transmission fluid flows through its own tubes while coolant flows through the main core. Heat transfers across the tube walls without mixing the two fluids. Any sign of fluid mixing indicates internal damage and calls for immediate replacement.

Suits Toyota RAV4 ACA20R, ACA21R, ACA22R and ACA23R models from 2000 to 2005 equipped with manual transmission and air conditioning. Fitment is as a direct replacement radiator assembly in the factory mounting position. Confirm core dimensions of 375 mm height and 738 mm width plus 34 mm inlet and outlet diameters against the existing unit before installation. Professional installation is recommended to ensure correct hose routing and coolant bleeding.
