Maybe a stupid question, but have you tried Water Wetter (I think that's what its called, never used it myself) or some similar product?

some people **not rotary** have success with that as it is supposed to help with heat transfer... but he needs to make sure he's got solid (and capable) system with no air.

Redline Water Wetter.

****sidenote... There is also Heater Hotter for the winter lol***

Water wetter is bad, it dissolves coolant seals. DON'T use it

You could drill a small hole in the thermostat plate to allow some coolant to bypass it all the time; I've done this when not running a heater core. It's best to run the water pump all the time, so as to keep some positive pressure inside the engine (particularly important in the area around the exhaust ports and the spark plugs), and the bypass acts as a restriction to allow some flow through (preventing cavitation) while maintaining pressure.

That is very good to know! Where would we be without forums?

great. I read this right after I just added water wetter. Time to drain!
By the way, Autozone rents cooling system pressure testers for free! just a $75 deposit

Gotta watch out though, the other extreme are kiddies who know nothing but run around spewing crap from their mouths. I once read someone suggest using hardware store washers to space rims......

Good friend/fellow rotary car shop owner years ago couldn't figure out why one car, flat out race car, needed rebuilds ever year from coolant seals just disolving. He found out that the owner would go home and put water wetter in the cooling system. So he went ahead and took a few coolant seals and put them in water, strait green antifreeze, dexcool antifreeze, and strait water wetter. He told me that withen 20 minutes the seals in the water wetter were disolving and turning stringy. Mystery solved.

I also bought a parts car once that was running on one rotor. Owner thought that the rear rotor was toast. Comp was fine, but the jacket rotted out a little and a section of the coolant seal was just gone. I knew the guy, knew the car, knew that he had put water wetter in the car after a mutual friend with a 500AWD eclipse used it after he started having issues. Eclipse was fine, few weeks later he thought he fragged the engine. Used iron from my collection and I had another good engine. It clicked years later when I found out about the water wetter. I always just thought that the seal broke loose but the seal itself was rubbery/stringy disolving

interesting. Thanks for the info. You'd think redline would put a disclaimer on the water wetter bottle regarding rotary engines. I wonder if they even know?

I got water wetter once in '97 for my REPU to try it out. It didn't do anything noticeable but I haven't used it since. Glad I didn't.
