FAQ for the last Day

  • Should coolant be filled to top of radiator?
  • Top off the coolant reservoir If the coolant level is low in the reservoir, you can refill it to the max fill line but do not overfill it. The coolant mixture expands when it heats up and needs the extra room. Keeping your coolant at the correct level is one of the ways to keep your radiator good working order.Should antifreeze be at the top of the radiator? The coolant reservoir has a cap that yo...


  • Should the radiator overflow tank be full?
  • To open your reservoir or radiator, place a rag on the cap while opening it, to ensure water doesn't split on you. The coolant amount that should be in the overflow tank has to be on the full level – this connotes the coolant is at maximum level.Should your overflow tank be full? You should never fill your overflow tank beyond the 30% mark because you might cause an issue that could lead to you ge...


  • Why is my coolant reservoir empty after filling?
  • Some of the most common causes include: A leaking head gasket or block. Leaking radiator cap or coolant reservoir hose. A cracked engine block that's letting water out into the oil pan/sump area (this would also cause your vehicle's dipstick to show an excess of moisture on its surface)There are a few different things that could cause your car’s coolant reservoir to be empty even though the radiat...


  • Should I add coolant to overflow or radiator?
  • This small reservoir on the side of the radiator collects any fluid that spills out when the radiator overflows. Tip: Most overflow tanks have a way to move the coolant they contain back into the cooling system, so it is a good idea to add the radiator fluid to this overflow tank rather than directly into the radiator.Pour the coolant into the overflow tank or radiator. The overflow tank is the pr...


  • Is antifreeze and coolant the same thing?
  • Engine coolant, also known as antifreeze, is mixed with water to keep the radiator from freezing in extreme cold and overheating in extreme heat. There are many different types of coolant, so it's important to know what variety is right for your car or truck.Should I use coolant or antifreeze? And now you know that antifreeze and coolant are basically the same thing and can be generically referred...


  • How much coolant do I put in the radiator?
  • The reservoir has minimum and maximum level marks embossed in the plastic or marked on it, so you can check the level without opening it. If the coolant level is below the maximum line or, worse, below the minimum line, you should add coolant to the reservoir to bring it up to the maximum level.To mix the radiator fluid properly, mix the coolant and distilled water in a 50/50 proportion. Fill an e...


  • Can you lose coolant without a leak?
  • Even if you don't see a leak on the ground, you could still have a tiny pin hole leak in one of the hose fittings. If the cooling system isn't perfectly airtight, some coolant may evaporate slowly over time. Sometimes you actually have a slow leak that allows coolant to seep out of the cooling system in liquid form.Where is my coolant going if its not leaking? If you've ruled out an internal leak,...


  • What happens if you put the wrong color antifreeze?
  • It's important to note that the type of coolant you should use can't accurately be identified by color. Using the wrong coolant can lead to corrosion and other damages to the radiator, water pump, radiator hoses, cylinder gasket, and more.What do I do if I put the wrong antifreeze in my car? To answer your question I wouldn't bother switching, if you decide to do so anyway simply flush the system...
