How can the Engine Oil Cooler be removed and inspected for damage on Mazda RX-7?

The oil cooler which is positioned at the bottom of the radiator but is independent of the radiator can be removed independently. Start with the removal of the engine under-cover and empty the engine oil. The next step involves removing the two oil hoses at the bottom left corner of the cooler with the help of two wrenches without damaging the cooler. Unscrew the bolts that hold the cooler onto the radiator and there are two bolts on the bracket and lower the cooler straight down the vehicle and out of the bottom. Look at the cooler to find out whether it is damaged, cracked, or leaking a lot, and then repair it, by welding it with aluminum, or changing the whole. Reinsert the cooler and loosely fit it with the brackets to the radiator followed by hooking and fastening the oil hoses. Lastly, screw the bracket bolts, put back the engine under-cover, add oil to the engine, turn on the engine and inspect whether it leaks or not.

How to remove and install the Engine Oil Cooler on Mazda Tribute?

Oil coolers are used on 2007 or even earlier 2.0L and 2.3L models and early V6 models only. Start by lifting the car and jackstands. The second step is to drain the engine coolant and the engine oil and then remove the engine splash shield. In the four-cylinder models (2007 and earlier 2.0L and 2.3L (and early V6), disconnect the two coolant hoses to the oil cooler, loosen the oil cooler mounting bolt and disconnect the oil cooler to the engine block, taking care to install a new O-ring. The reverse process is the installation which involves the installation of the oil cooler on the mounting bolt tightened to the required torque. In the case of 1.5L and 1.6L, loosen the hose clamps with the pliers in order to unconnect the coolant hoses with the oil cooler. Use the Allen wrench to loosen the screw through the center of the oil cooler adapter bolt until it is loose, then remove the oil cooler by removing it out of the engine block and throw out the O-ring. Check the block surface, replace a lost O-ring on the oil cooler, apply a little oil to it and place the cooler in place, tightening the adapter bolt to the correct amount of torque.

Mazda Engine Oil Cooler

The Mazda engine oil cooler has a double role: lubrication and cooling. It is situated close to the radiator, so it maximizes the airflow, allowing for effective cooling. The oil cooler keeps the oil in its proper temperature range while maintaining its lubricating properties. Engine oil not only serves as a lubricant but also helps cool down the motor. In some instances, it can get contaminated and affect its performance. Replace your oil cooler if you have driven over 50,000 miles in your car. Here are signs of an ailing oil cooler that you need to be aware of: loss of engine power, which results from dirty oil; misfiring due to fouling by oils, resulting in poor general vehicle performance; increased coolant temperature occasioned by contamination of engine oils. Thereby, immediate redress should be made to avoid any possible damage that might occur. Always check your Mazda engine oil cooler regularly so as not to compromise safety or reliability while driving.
