  Q: How to service and repair the radiator on Scion tC?

  A: Start radiator servicing by gripping and removing the radiator drain cock plug while extracting its O-ring. Install the claw of Special Service Tool: 09230-01010 (09231-01010, 09231-01030) on the overhaul handle while adjusting dimension B to the range of 0.2 to 0.3 mm using the stopper bolt to protect the claw from damage. The core plate receives treatment through straightening using the same tool until the stopper bolt terminates the process. Start faucet drain removal that clears the radiator tanks one by one through targeted light hammer tapping at their brackets followed by O-ring removal from each side. Examine the radiator core sub-assembly for damage by using pliers to fix any core plate groove deformed areas and note that replacement will be necessary if bottom damage occurs due to its two permitted recaulking operations before necessary change of unit. The left radiator tank installation should begin with a check for foreign objects in the core plate groove followed by addition of the new O-ring which must be untwisted before installing tank placement and final tapping to reduce gaps. Repetition occurs for the installation of the right radiator tank. To perform the core plate caulking process, use Special Service Tool: 09230-01010 (09231-01010, 09231-01020). Insert the punch assembly into the overhaul handle and adjust the stopper bolt until the dimension B measures 8.4 mm. After installing a new O-ring onto the drain cock plug users should install the plug.
