Dishwasher Soap Flush Update

[55 Fargo]

Hi all, re-filled the cooling system with clean water today, for the final rinse/purge of using the Electrosol treatment.

The system took somewhere around 17 US quarts to fill, does that sound right.

I filled up the rad and block have a small hole in t/stat to allow air to escape. Got it filled up, to just above the rad core in the top of the rad, then started engine, let it warm up, added some more water, temp gauge shot up to 180, then t/stat opened, temp then settled to 170, I added the rest of the water to bring it's level to 2 inches below rad cap hole.

The temp gauge in car was now settled at 160, I would give the engine some gas, the temp gauge would drop to 150, the temp in the rad was around 150, I have a 160 thermostat and the ambient temp at this point today is a yucky 34 . If I let the engine idle it would settle in at around 160, the temp would be 155 in the top of the rad, if I revved up the engine for a few minutes, the temp gauge would drop to 150, and you could tell the t/stat would close a bit, the temp would come up a bit. The whole time the heater in the car had a nice even temp, stayed warm

I could stick my finger inside of the rad, it was good and warm, but would not burn my fingers.

The rad had an even temp change from top to bottom.

So what is going on here, even when it was colder, I could not let here idle like this for 20 minutes and have the temp remain at 150 to 160 on the gauge, it was always 165 on the gauge and 155 in the rad, now the rad temp and gauge temp are very close.

Could it be possible I either had blockage before, or not enough coolant, causing problems.

The real test will come when the weather warms up next week, it is very chilly here today.

I would not want my engine to run at 155, on a longterm basis, would want it up closer to 180.

Is it okay for me to keep straight water in the cooling system for a week or 2 , so I can see what she will run at, I have it indoors, so even if it gets cool at night the temp in my garage will be above 40...........Thanx guys Fred

Fred I made some suggeestions converning water coolant mix on one of your other threads. I believe when you noted it was nearly 30 degrees cooler today than the other day you expained much of the difference in today's results. Go for ride, see what happens.

Just emptied the rinse water, it came out of the block like a race horse relieving itself, water was clean with a few crumbs that flew out of the block first.

Next will run straight distilled water, with water pump conditioner, such as redline water wetter, see how that goes on a hot day, if all well, will introduce 25 % antifreeze, and strengthen to 50 % in fall.

I need to find out on a hot day what the temps will be doing on the highway..................Fred

Filled the cooling sysytem up with deionized water and 25% antifreeze, went for a highway drive, ran at 160 all the way, but it is miserable cold here tonight, around 30 and windy, so not a very good time to decie, she is cured of her poor cooling abilities..........Fred

Fred, on a flat rock or in a bucket? Flat rock, she'll run at 180, bucket, she'll top out at 160.
