I have a 98 Ford ranger with the 3 liter engine. The original radiator side tank cracked so I bought another radiator. I am going to do a citric acid flush on the system before I put the new radiator in. I am looking for a cheap reliable coolant to use. It has always had conventional green. I see Walmart has all makes coolant for 9.88, is that ok to use? I'm not up on coolant's and I know there are oat and hoat and many others. I am just looking for something cheap that will offer good protection and not eat my gaskets like those early gm cars with the v6.
