A truck transmission repair is not an effortless project. However, when you complete the job properly, you will again enjoy a cooler line that functions as it should.
Truck transmission cooler lines keep your transmission from overheating, particularly during summer days when you are stuck in a traffic jam with your air conditioning on full blast. Cooler lines convey the automatic transmission fluid further than the transmission’s hot gears. The fluid cools a little during the transfer via the lines prior to returning to the truck’s transmission. Without that kind of cooling mechanism, its transmission fluid can get extremely hot and cause the transmission to stop functioning.
Step 1 – Familiarize Yourself with the Cooler Line Operations
Immediately automatic transmission fluid approaches a particular temperature, its viscosity alters and the liquid thins greatly. The transmission fluid no longer accurately lubricates the moving components of the transmission, while the truck’s gears can stick or never shift at all. The fluid, being a lubricant, cools the transmission in order to keep it from bending and warping.
The cooler lines help the fluid in cooling by eliminating it from the warm transmission, then permitting it to pass along the cooler zone. Remember that cooling equally prolongs the fluid’s life. Nevertheless similar to any truck tubing, the transmission cooler lines can equally develop leaks. Leaks will cause your transmission to overheat and fail if you do not restore the cooler lines at once.
Step 2 – Purchase Transmission Cooler Lines
You can buy cooler lines designed specifically for your truck’s model. Trucks require two separate lines: a return line and a feed line. These lines are twisted into particular shapes to mount to the truck’s underside. While regular brake lines can be modified in order to fit the truck, they are usually too short for the task and necessitate huge rerouting of the truck’s transmission cooler lines.
Bear in mind that standard cooler line sets are offered for $30 dollars or less. If you prefer the most proficient cooling system for the truck’s transmission, consider including a second cooler line to the factory-installed line. Keeping your transmission fluid cool will prolong the entire transmission’s life considerably.
Step 3 – Change the Cooler Line
Because the detached lines will possibly weep fluid, you have to place a drop cloth in the floor after raising your truck with a jack. Next drain the transmission fluid in a pan and reserve it to fill up the system afterward. After removing the old cooling lines, you will deal with the radiator. You have to verify that the replacement exactly match the former parts. Given that hard tubing is prone to leaks once bent extremely, you should bend the tubing only lightly to keep its original shape.
Repair and mount first the top line to keep blocking access along with the lower line. Mount the bottom line; then tighten all the connections with an adjustable torque wrench. Lastly refill your truck’s transmission fluid. Test the installed lines for any leaks before you start driving the vehicle again.
