Even if you find a mechanic that works at a fair rate, paying someone to replace your Nissan Titan radiator is expensive. With a few handy tools and some time, you can replace your radiator yourself. As you see below, here are the tools and the proper steps needed to replace a radiator on a Nissan Titan.
1) Phillips Screwdriver
3) Drain Pan
4) Ratchet and Socket Set
The Radiator can be purchased at any local auto part store or online to be shipped to your house when you are ready to work on your vehicle.
Either of the two work spaces listed will work successfully. There needs to be enough ample space that is leveled to allow you to work in the front of your Titan with the hood open. No work should ever be done on a slanted driveway or garage without the parking brake set accordingly.
1) The drain pan needs to be placed under the radiator. The radiator cap needs to be loosened if not completely removed. The driver’s side drain plug on the radiator needs to be opened and the fluid allowed to drain.
2) Once completely drained, go underneath the Titan with a wheeled cart. Once underneath, remove the undercover with the ratchet and socket set so that you have clean access to the radiator from the bottom.
3) Unattach the hoses connected to the old radiator by loosening the clamps with a set of pliers. You may have to use a screwdriver in this instance if the clamps are a different brand or have been replaced.
4) Remove air component parts, such as the air cleaner, so you can get more room to remove the radiator. Once the air parts are removed, carefully remove the lower half shroud of the radiator and watch for any excess liquid. This may be removed manually or may require a screwdriver to assist in the removal.
5) Back on top under the hood, remove the upper half shroud of the radiator by unscrewing it using a screwdriver. Once removed, you will have to unattach the hose leading from the reservoir.
6) Remove the brackets and fasteners from the radiator and lift the component out of the engine.
7) Install the new radiator into the engine and re-install the brackets and fasteners to both the upper and lower half of the component.
8) Place the upper shroud back on the radiator and secure properly with the mounting screws supplied with your new component. Once everything on top has been fastened, reattach the reservoir back to the radiator.
9) Place the lower shroud back on the radiator and reattach the air components removed during the above procedures. Once all parts are secures, the upper and lower hoses connected to the radiator need to be clamped accordingly and then the engine undercover would need to be re-attached.
10) At this point, the drain plug should be tightened and the radiator then filled with a combination equal to half antifreeze and half water.
