Hello everyone and welcome back to capcounter our series of short articles on automotive tools and how to guides for the new weekend warrior mechanic. These aren’t written for the professional but for the average Joe who is looking to get his hands a little dirty. In today’s article I’m going to talk about opening the cap of an older style radiator. This is the type of radiator that you will find in cars that don’t use the current system with a reserve coolant tank on the fender well. newzhit
The first step is to make sure that the radiator and engine are below operating temperature. Ideally you will want to have let the car sit overnight if possible. However, skylightmarijuana since that is not always possible, just make sure it has sat long enough that the water is below boiling temperature. A great way to do this is by grabbing the squeezing the upper radiator hose. If it’s hot, then don’t open the radiator.
You will want to appoura use a fresh towel or rag over the radiator cap when removing it just in case there is still any steam trapped in the system that might have otherwise burned you. Turn the cap counter clockwise until it’s first catch or stop. That will allow any remaining pressure to escape. If you do see any liquid or a lot of steam, immediately re-tighten the cap and come back later because it’s not cool enough yet. If you don’t see either of those, buzzindeed continue to turn the cap counter clockwise until it’s loose and remove it by tilting it towards you to block any steam that still may escape. helpforsoul
You will now have removed the radiator cap safely, and can look into the radiator to see what the fluid level is. If low, mix the proper kind of fluid with a 50/50 ratio of fluid and water and fill the radiator. Once again, do not do this while the vehicle is still warm. You could potentially seriously burn yourself if the cooling system is still at operating pressure and temperature. For more info please visit here:-zprostudio.com
