Surprisingly, I can exchange almost all the coolant in the system by using this method (according to cooling system specs for my vehicles)!Īlso, my GM cars have small brass coolant bleeders on the high point of the system at the thermostat housing. I have a beer and listen to the Rolling Stones or Bee Gees. Sarge goes for breakfast during his cooling system service. The coolant is drained directly into gallon jugs sitting on the driveway, no fuss, no mess. Then I use a small plastic syringe (a couple bucks, sold in auto department of Wal-Mart) to create a suction and begin a siphon. I put in the amount that I take out.īack to coolant… I periodically run a small diameter plastic tube straight down the side of the radiator tank, directly below the cap/neck until it bottoms out in the radiator. I have a Liquid-Vac that I use to periodically extract most of the transmission fluid through the dipstick tube, no fuss, no mess, goes right into bottles. I do as much car maintenance as I can from the top of the car. I’d use the specific coolant required, not some universal stuff. Unpressurized fluid boils at a lower temperature.ĭoes it have to be genuine Toyota Super Long Life Coolant? And how many gallons do I need when flushing the engine coolant? Do NOT allow it to heat up with the radiator cap off. Park the car such that the radiator fill hole will be the highest level in the system and run the engine with the radiator cap open and the heating system ON to open the path to the heater core. Your car has no such protection.Īnd be sure you burp the air out well after refilling. Your stomach contains enzymes to protect it against the hydrochloric acid it uses to break down food. Safe to drink, but not safe to use in the car. While safe to drink, a lot of tapwater contains high levels of minerals and, in the case of the water I had from my last house, is highly acidic. I can tell you from experience that using tapwater can cause problems. I also agree with using only distilled water (about $1/gal at any grocery store) if you buy the “concentrated” antifreeze and mix it yourself. I drin it by disconnecting the lower radiator hose. I agree with the practice of draining as fully as possible and refilling.
