Odd story. So I was working on my TII a few weeks ago, and replaced the upper rad hose and some other stuff.
My "helping" friend filled it up with the jug of green stuff in a coolant jug. About two weeks later I realized it was simple green.

I drained the radiator, block, and disconnected all the hoses to drain is throroughly. I then ran water though it with the block plug out. I used REAL coolant and I've kept a sharp eye on the coolant temps, which have been ok (under 90C).

Any possibility I damaged coolant seals?

 

i doubt they have been damaged. but i bet you have really clean coolant passages...

and your friend is a dumbass. smack him.

 

Simple green only has very dilute levels of weak solvents, so paper gaskets should be fine. It's a water based cleaner afterall.

Your aluminum radiator may have some oxidation inside though. You might find deposits in your coolant for awhile, but it should be fine.

If it was in a gallon jug looking like coolant, it was probably the concentrated stuff...

In any case, I wouldn't be worried about it unless I'd seen it overheat while it was in the system.

Be happy! You no doubt have the cleanest cooling system in any RX-7 on the face of the earth!!

 

Ha ha, thanks.
