The Goods On Coolants

[KrazyKong]

After searching these forums about coolant info, it hit me we need a thread just like the excellent Oil one just for coolants. Maybe one of the admins/mods might agree and sticky this right next to the Oil one

I was having a talk today with my neighbour about coolants. I'm currently replacing my heater core and thus will have to do a full coolant flush. Having only done one a few months back this shouldn't be a problem. But the discussion soon turned to what type of coolant to use. I know alot of folks here use different coolants, with some stating the Nulon Long Life Concentrate is one of the best. I was using previously a cheap coolant from K-Mart. What was interesting in this discussion was that I had thought all coolants "cooled" about the same, and the only difference was the length of time it lasted, or whether it had rust inhibitor or antifreeze in it. But it turned out, that after putting in this Nulon my neighbour mentioned how the temp gauge was reading lower. And his coolant was still clean and green before he did the swap. I know it's only one car, but having an engine run cooler is a great thing. Based on this, I'll be trying the Nulon stuff myself.

What about other peoples experiences? How have you found a coolant that works for you? or are happy with it, but want something that works better.

I was happy paying $5 a bottle for the stuff I was using before. But had I known this Nulon stuff could cool a car better, I would have purchased it immediately.
