A clogged or damaged radiator will greatly affect the cooling system in your Honda CR-V. You need to remove the radiator in order to clean it out or possibly replace it altogether. The radiator is mounted in the front of the engine compartment and removing the unit itself is a very simple procedure. The more difficult task lies in disconnecting all the fans and hoses connected to the radiator so you can then pull it out.

Disconnect the battery from the CR-V by unplugging the negative battery cable. Apply the parking brake and block the vehicle's rear wheels.
Raise and secure the front end of the CR-V on jack stands. Remove the splash shield beneath the radiator. Raise the hood and remove the radiator support cover at the front end by removing the pushpin fasteners with a forked tool.
Drain the engine coolant. Place a large container under the radiator's drain plug and remove the plug -- it may require pliers to move it. Once the coolant is drained from the radiator, drain the rest by removing the engine block's drain plug.
Disconnect the electrical connectors to the cooling fans, unclamp the wiring harness and position it away to the side. Remove the battery and its tray and place its wiring harness away.
Unplug the wiring connectors to the cooling fans. Remove the upper and lower radiator hoses by squeezing their clamps with pliers and sliding them off the radiator neck. Unscrew the mounting bolts connecting the cooling fans to the radiator and lift them out of the engine compartment.
Detach the transaxle cooling lines from the radiator's lower tank if the CR-V has an automatic transmission. There is a hose on the left and right sides of the radiator that are attached with quick-fix connectors. Depress the tabs to disconnect them.
Remove the brackets holding the radiator in place. The brackets are bolted in place on opposite ends at the top of the radiator. Use a wrench to remove the brackets.
Lift the radiator up and out of the vehicle. Make sure no coolant spills onto the body and avoid scratching the paint as you remove it.
Tips and warnings
- Check the radiator for any leaks and damages after removal. Spray the back end with a garden hose nozzle to remove any bugs or dirt. Flush the radiator with the hose before reinstalling it in the vehicle.
