How to Install a Radiator - KOYORAD - Track Life Episode 4
Drain the Radiator Fluid Out of Your Vehicle
Firstly, make sure that your vehicle has cooled down to prevent any accidents. Uncap the radiator where the fluid goes into. Open the peacock from the bottom to release all the radiator fluid from the radiator. Make sure to place a bucket/something to catch the radiator fluid with underneath the vehicle.
Remove Your Radiator Step by Step
Start by unscrewing the intake box bolts from the vehicle to gain access to the radiator tube. Once that has been removed, disconnect the fan from the harness. Make sure to disconnect the fan for both the radiator and the AC condenser. Next, remove the radiator hoses. Wait until the radiator has completely drained. Remove the top hose first, then the bottom. Remove the overflow. Remove the brackets supporting the radiator onto the chassis. Make sure to unplug the fan's temperature sensor from the bottom of the vehicle before removing your radiator. Once all necessary parts have been removed, you can now remove the radiator out of your vehicle.
Transfer Your Reusable Radiator Parts
Once the radiator has been removed out of the vehicle, set it firmly on a surface and remove the 10mm bolts for both top and bottom fans. You can also reuse the rubber grommets attached to the bottom of your old radiator. Unscrew them from the radiator to attach to the new one. Radiator fans' temp. sensors may also be re-used, so make sure to remove and set aside. Once all the parts have been detached, transfer them over to your new radiator in reverse fashion.
Place Your New Radiator Into Your Vehicle
Re-insert the new radiator in place, sitting into the rubber grommets. Re-attach the brackets securing the radiator. Re-install the radiator hose, which is just the exact opposite of the previous hose removal step. Re-install the radiator temp sensor. Make sure you hear a click when doing so. Once the radiator hose is back on, re-install the intake box and prepare to fill with coolant.
Refill Your Radiator Cooling System
There are 2 ways do do this: 1) The budget friendly way, using a funnel 2) Using a vacuum-technology pump To use a funnel, uncap your radiator fluid tank and insert the funnel. Fill the funnel to about half way its capacity. Open the 2 bleed screws in your vehicle: 1 on the intake manifold and one on the back of the firewall. Once coolant starts to release form the 2 bleed screws, close them back in and finish filling the system. The vacuum pump way: use compressed air to remove any remaining coolant. Once the coolant has been drained with the vacuum-powered tool, you'll notice the radiator has been fully collapsed with negative pressure. On your tool, open the valve of the fill tube and you should notice coolant injecting back into the radiator system. Once your radiator fluid has been filled, you can start your car to make sure your radiator fans have been properly set.
