Put Koyo in today...
 

and it was a b-i-t-c-h. Well, let me rephrase. getting 16 yr. old, rounded off, striped, etc. bolts off was a PITA. The radiator actually went in pretty smoothly, along with the new hoses and thermosat. But my question is: I really did not flush the new radiatior. I just got the hose and let fresh water in for a min and let it run straight through. After that drained out, then I put a 50/50 mixture in. So should I reflush to be on the safe side with some of that prestone crap? Or am I cool as it stands. :confused: Thanks

reflush just to be on the safe side.

Why would you flush a new radiator? That makes no sense. Just flush the engine.

Damn, sorry to piss in your wheaties. I dont know, maybe there is some junk in there from the factory that needs to be cleaned out from the assembly process. Making sure everything clean makes sense to me.:confused:

Oops, the triple post

My Bad

strange I have removed a rad in like 30 min

Did you have to modify the battery tray with this radiator?

WEll, I would go flush it now...

Don't use tap water. Too much shit in it. Use DISTILLED water. Distilled is "pure" water.... spring water, all that shit isnt pure. And a garden hose is probably full of crap. Tap water is not what I would put in my radiator...

50-50 mix of coolant and distilled water.

w3rd on the distilled water.

throw in a bottle of water wetter for good measure!!

Craftsman Bolt Out's man. You have a 2g RX-7. Get a set.

Does that unit have a hookup for the heater?

DO NOT>>> DO NOT>>> DO NOT >>> DO NOT add water wetter....

Dave at KDR told me not to put that crap in my engine, he said (drag on a cig... exhale.... talking with smoke comming out his mouth) "it eats the water seals homer..." dont do it!" (another drag on the cig.)

i figured screw it, i'd give it a shot since I was going to rebuild my engine anyway...

about 1000 miles after i put it in, my car started drinking water, running hot, and the exhaust smelled sweet. and the final shot was that it started fouling out plugs everytime you shut it off (sucking water into the housings)

thats right, the seals were on their way out... when we cracked the engine, the seals looked like someone had poured acid on them and they had tuned to powder..

Luckily, i had taken the car off the road before i did any damage to the housings, thank god it never really overheated....

i have heard you have to be exact with the amount of water wetter you add to the coolant system. Perhaps you put too much?

The previous owner of my Turbo2 used water wetter, and the engine was at about 141k miles, and doesnt have a coolant seal problem. Im not trying to promote the use of it, just giving my own personal experiences...

I totaly agree here. I lost my motor to Red Line Water Wetter. I used it exactly like the directions on the bottle stated to use it. Just to let you guys know my T2 was running mechanicaly perfect, and was running cool as well. It all started when I went to a Performance Shop to buy a couple of things I needed, so I noticed the Red Line water wetter, and decided to buy it, and give it a try. "Let me tell you that was the biggest Fu - - - - - mistake I made was to buy that shit, and put it in my radiator" ! After close to a couple hundred miles I had "EXACTLY" all the same symptoms "Years of Decay" is describing. When I opened my block up the water seals were disinigrated from that shit. :mad:
