Built for Transmission Fluid Routing
This Dorman 624-552 transmission line is engineered to replace a worn or leaking cooler hose that carries automatic transmission fluid between the transmission and the cooler. The molded metal-and-rubber construction supports a secure fluid path, while the OE-style configuration helps match the original inlet upper routing on Buick Rendezvous, Pontiac Aztek, and Pontiac Montana models. This part cross-references OE numbers 5801440 and 10360648 for the same application.
Common Problems It Can Address
- Transmission fluid seepage at the cooler line
- Cracked or deteriorated hose material
- Corrosion or damage in the original line assembly
- Restricted fluid transfer between the transmission and cooler
- Fitment issues with a damaged inlet upper hose
Installation Notes and Tips
Verify the inlet (upper) position before installation and compare the end style, hose shape, and length to the original line. The hose uses male threads on end 1 and no end fitting on end 2, and the 2005 Pontiac Montana application notes a 12.25 mm end of hose to flare measurement. No gasket or seal is included, so inspect the mating connections and sealing surfaces before service.
Quality Assurance
Dorman replacement parts are built to match the function of the original component using quality materials selected for transmission fluid service. Part number 624-552 is designed for direct replacement use on the listed Buick and Pontiac applications.
