How to Install a Radiator
When you notice that you have a strange odor while driving your car or truck or you see steam curling out from under the hood you may need to check your radiator. It could be that the cap is bad or a broken hose. Should it be the radiator and it needs replaced, do it yourself and eliminate the cost of having a mechanic do it.
Once you have ascertained that the radiator needs replacing simply follow the proper procedure and it can be completed in a short order. It is not that difficult and requires no special knowledge.
- Drain the old radiator after the engine has cooled down for at least half an hour. The drain, which is called the drain plug or petcock, is on the bottom of the radiator. Collect the coolant for re-use in a clean container. Be sure to take off the radiator cap so it will all drain more quickly.
- Remove the radiator hoses from the top and bottom of the radiator.
- Disconnect any other lines attached to the radiator at this time.
- Locate and remove the mounting points and any fasteners holding the radiator to the fan shroud. Keep track of these items, as the new radiator may not come with them.
- Slide the radiator straight up and out. Be careful not to hit the fan blades. There could also still be some antifreeze so handle carefully.
- Compare your new radiator side by side with the old one to make certain they are the same.
- Lower the new unit into position carefully and do not damage the fins on the radiator or the fan. It should slide easily into the rubber-mounting washers on the bottom of the housing.
- Locate your mounting screws and start them in to finish alignment. Do not over torque these screws as they are going into clips most of the time.
- Install your hoses back and tighten them down. If they are being difficult, try putting some coolant on the barbs and that should help.
- Tighten everything back down, replace your coolant and check for leaks.
