Antifreeze...


I'm getting ready to replace the thermostat in my truck and flush the system.

The parts guy at Federated (knowledgeable and helpful chap over the years) said that as long as I flushed the system well, I could use regular antifreeze and not the expensive HOAT variety.

Anyone got any input on that?

Re: Antifreeze...


Pretty sure you can, you'll have to change it sooner though, so maybe factor that into the decision.....

Re: Antifreeze...


You know if you would just use spring water you wouldn't have to worry about it. It doesn't freeze.

Re: Antifreeze...


You'll probably be okay if you're flushing but how much $$ are you saving? If you plan on keeping the truck I wouldn't change even if it can be mixed.

Re: Antifreeze...


Should be no problem at all pending you get ALL the old ****e out.

Ive done the opposite on my motorcycle. It rolled off the assembly line with IAT coolant. The old green stuff. I cleaned the system out and switched to a P-HOAT coolant.

Ive not had any temp issues before, or after. I did have to drain all the new coolant a few months after it was changed in order to perform an unassociated repair. The coolant looked to be just fine at that point.

I refilled with P-HOAT again and it's been good since then. That was 4+ years ago.

In my experience, yes, you can switch. Cost difference is negligible IMO.

Re: Antifreeze...


I have done the same with my ATV too. Switched from IAT to P-HOAT. No issues with it after switching. Its been a few years.

It all started with my dirtbike. I always ran IAT (old, green) in it. IAT antifreeze relies on silicates as the main source of corrosion protection. That bike seemed to go thru water pump seals every couple seasons. Finally, I bought new bearings, impeller, and seals. I flushed the coolant and switched to P-HOAT (zerex asian). Never had an issue with the pump seals again. Sold the bike to a friend. He hasnt had issues with them either.

Eventually, i switched the ATV, and street bike too. When i first switched the dirt bike, i was grasping at straws. I was doing everything i could to prevent another break down. Im not saying the antifreeze change actally helped. Im sure it was the new parts that did it. But, when it came time to work on the other toys i figured i may as well have the same coolant in all of em so, everything got switched.

Re: Antifreeze...


Long life, and use purified water. Never use spring water, or well water. PH has everything to do with the anti-freeze turning into a battery. Speaking of which use your DVOM to check the voltage before draining. The voltage in the cooling system is what causes all the issues.

Re: Antifreeze...


I don’t know about the haot stuff but , all my vehicles theat call for dexcool ( the orange stuff ) I use regular green antifreeze in without any problems. One of which has 380,000 miles on it. More of a concern would be the water used , if you have questions about the water quality, use distilled water or the 50/50 antifreeze.
