- [05191925A](/bulletins/10149006.md), 2018-11-26, Service bulletin: ENGINE AND ENGINE COOLING:COOLING SYSTEM:RADIATOR ASSEMBLY. Radiator If vehicle comes in for transmission fluid leaking from trans\-oil cooler fittings on the radiator, please check the following before replacing the radiator/cooler:\~ 1. Remove both of the transmission lines from the cooler?s top/bottom flared fittings on the radiator. \~ 2. Loosen the hex nut on the top flared fitting on the radiator tank.\~ 3. Torque the top flared fitting to 235 \+/\- 15 Lb\-In.\~ 4. Torque hex nut to 100 \+/\- 10 Lb\-In.\~ 5. Repeat for bottom flared fitting.\~ 6. Reinstall transmission line per normal installation procedures and ensure correct fluid level.\~ \~ If vehicle is in need of a new radiator for another reason, check the new radiator for correct torque on the trans\-oil cooler fitting per steps 2\-5 above.\~ \~ If radiator has a yellow mark by the trans\-oil cooler fittings the torque does not have to be checked.
