What is the best antifreeze to use in a 1995 viper?

Answer 1

There are many antifreezes on the market which makes choices difficult. Certain wetting agents are added to antifreezes which help absorb heat and give lubricity to antifreeze. There is a drawback to this, it is cycle time. The antifreeze works great for so many cycles or time exposure to metals. Antifreeze also changes pH value over time. With aluminum radiators, iron pump impellers, iron metal pump seals, rubber hoses, some iron heads joined to aluminum blocks antifreeze moves heat all over. The radiator is the heat eliminator however with the drastic heat change that takes place in a radiator it takes a beating by collecting the impurities. Change your antifreeze once every three years whether you drive the car or let it sit. Pull your thermostat and boil it in baking soda for two minutes. Drain and dispose of the antifreeze, flush with good clean water, fill the system with clean water and no thermostat add one heaping tablespoon of baking soda for each quart of water, take your time mix it well, leave the radiator cap off, run this engine until your gauge moves to half the normal temperature. Now you have a clean system, drain it, change whatever hoses you like, put the thermostat back in but drill a .0625 bleed hole in every thermostat from one side to the other. This one hole to allow the air to bleed and prolong thermostat life. Now mix your antifreeze 50 50 any recommended factory brand with distilled water, add a wetting agent (used in diesels) for a hard towing vehicle and i mean hard or you waste your money. These simple steps take time but add life to hoses, pumps, and free up a few horsepower by allowing more constant operating temperatures. As a safeguard pressure check your system during the baking soda cleaning to 1.5 times the radiator cap rating, if something goes fix it. The baking soda will find the smallest leak and its cheaper to fix with a little lost baking soda instead of antifreeze.
