Preferred Coolant For Iron Engines With Aluminum Intake & Radiator

[GoDadGo]

What coolant do you guys prefer for your "Iron Engines" sporting aluminum intakes and radiators?

• There are so many coolant types out there that they've got my head spinning.
• My climate is mild so the car will never be winterized & stored.
• Living in the Deep South has some advantages.
• Hurricane Season Isn't One Of Them!

Thanks-N-Advance!

I'm going to try waterless

I have waterless in mine and so far so good. I had to drain it once to replace the oil pan and water pump gasket but I used a clean pan and put it back in. If you've ever had water in your system there is a flushing chemical you have to use first which costs as much per gallon as the coolant. Once it's in the coolant lasts basically forever.

For my street cars I use whatever the OEM recommends -- these are usually longer lasting types (none last forever). However, for my race car I use the tried and true 50/50 premix (I use Peak but choose your brand) ethylene glycol. It's relatively cheap and easy to get rid of. I also have to pull my engine every two-years for SFI certs so the coolant will never stay in there long enough to gel up.

I also use an anode plug that I replace yearly as it’s eaten away to deal with the galvanic effect of the dissimilar metals. Got it from Summit Racing and you just need a spare port (mine is in the lower intake). I also add VR-12 a “vitamin” additive for your antifreeze. It has slightly lowered my operating tempature...

I went with the Dexacool (Prestone Brand) coolant.

I had that stuff in my old 1995 Corvette that I recently sold to a friend of mine so that he could get back into the Car Hobby.

It is also in Baby Go-Dad's 2000 Camaro.

Since those cars have iron blocks, with aluminum radiators I figured why not run that stuff since I've already used it.

Thanks For The Input Gang!
