Sound off!

Have you done the coolant flush procedure? Please tell the story. I made a passing comment in a recent thread in the Canadian Forum...

https://www.rx7club.com/forum/showth...hreadid=132011

and now I feel like I'm getting gang-banged by people who are a little quick to rant about something that they have no experience with.

I can't be the only one who's done this procedure.

 

wow I don't about that... god knows what the temp really is when it hits H LOL... probbaly like 250F.

 

Well, Im not going to say anything negative about it, Im sure RETED has his reasons for doing that, and it may work very well, but I personally would never purposely overheat my engine.

 

I followed the procedure when I flushed my TII, it was running fairly hot a little over 1/2 on the gauge.

After filling the radiator with the solvent and distilled water, I couldn't get my needle on the gauge to go all the way to H, but it got close and then the buzzer went off. I drove it back to the garage, about 200 feet, and shut it down. After 30 minutes, I opened the cap and this white gunk came out. I started the car and let it run with the hose in the filler cap until it ran out clear. I filled up with water wetter, distilled water, and a little coolant, now my temps never go over 1/4.

I'd say it works.......

 

I did a flush this weekend but i had no idea that there was a write up on it...
I went got a thermostat, pensoil super flush, and pensoil rush protectent,

I replaced the thermostat ran the flush then put in coolent and the protectent and i was runing at over half to 3/4s now i'm runing 1/4 to 1/2

 

Didn't know there was a link floating around in there...

I should've posted in here for a more appropriate place to post.

Don't worry guys, I'm going to edit and paraphrase and copy my reply onto my website soon...

Normally flushing procedures call for running the motors at normal, operating temperatures for approximately 10 minutes; read the container for detailed instructions. We've found that this does not sufficiently flush the motor of contaminents. We recommend a modified flush procedure:

1. Drain entire cooling system (of coolant) - on the 13B, use the radiator drain (plastic plug) on the bottom of the radiator and the engine block drain (14mm hex plug) located in the driver's side engine mount bracket.
2. Close drains and fill with your favorite flushing additive. We recommend using Prestone Superflush™.
3. After pouring in bottle of Prestone Superflush, top off with water as per instructions on the Prestone Superfluch bottle. The cooling system should now be filled with the Prestone Superflush and water mix.
4. Start the car and run till the cooling system boils over. Yes, you heard that right - till you see steam coming out of the overflow bottle. You might need to drive the car around the block a few times to get it to steam; it might not steam just idling in your driveway. Try not to drive very far away from home when doing this. Stay calm and do not get alarmed when the temperature gauge hits "H" and the low coolant light/buzzer goes off. As soon as you gauge hits "H", calmly drive back home and kill the engine.
5. Shut the engine down and let it cool down.
6. Drain everything out of the cooling system - it should look milky white!
7. Flush the cooling system with as much running water until everything comes out clear. Don't forget to flush and clean out your overflow bottle also!
8. Drain and fill with your favorite coolant and (distilled) water to the appropriate ratio depending on your climate. Again, don't forget to fill the overflow bottle also.


This sounds like a disaster waiting to happen. I would really like to hear your reasoning for this method Ted. I am in no way trying to argue the matter; just trying to make myself believe it.

I'm kind of a novice here. The traditional (most safe) method of flushing a radiator would be...what? All help much appreciated

 

Just follow the instructions on the bottle.

There are no special procedures for flushing a rotary (none that I've encountered.)
