Questions & Answers
Do I add AS105 every time I flush if it's necessary to do so?
I put the stuff in, drive around for a day, flush the motor with clean water a few times until the water looks clean, and then repeat the process. I use another dose of Flush, then drive for a day, then water several times until the area is clear. In my case, the "extra" crud that the second flush removed surprised me.
I couldn't find any mention of driving around in the directions. Is this a different version of the cleaner, or am I missing something?
Standard flush no, there are two sets of instructions. For severe buildup or something, it says to leave it in for a couple days, but be careful not to let it freeze. It takes a long time to get everything out because my cooling system is only 1. I used 8 gallons and the entire bottle, and I ran it through a heat cycle twice, cooling it to over 100 degrees Fahrenheit each time. It appeared to aid in the removal of any film that had formed on my rad cap.
What is the proportion of each ingredient in the mix?
For up to 12 quarts (3 gallons) of water, one 22 oz bottle is sufficient. If your total capacity is less than 12 quarts, go ahead and use more; if your total capacity is greater than 12 quarts, go ahead and use more. You can leave it in the system for as long as you need to achieve the desired results. No part of the cooling system appears to be harmed. The most common cause of radiator clogging is lime deposits, which are the most difficult to remove and may require multiple treatments. This is due to the antifreeze being diluted with tap water. Only use distilled water when mixing the Prestone flush with it.
Is this product suitable for motorbikes?
Why not? I'm not sure. Steel and aluminum parts are found in car engines.
Selected User Reviews For Prestone AS105 Total Cooling System Cleaner for Radiator, Heater Core, and Hoses, 22 oz, 6 Pack
This is something I've used before and it's always worked well. Antifreeze that is too old has a nasty habit of corroding an engine's internals and causing damage that you may never notice.
Hint: If you buy a complete flush kit, you must also remove the thermostat to flush the motor; otherwise, you will only be flushing the heater coil and not the engine. Here's how to do it right: buy this stuff, pour it in, drive around for a day or two, and let it cycle into the engine, water pump, and heater core. Remove the thermostat (now is a good time to replace it) and reconnect the connector without it. Turn on the water hose and start your engine, then wait until all of the water is perfectly clean (around 5 minutes should suffice, more if desired). Turn off the water, close the flush kit with the cap, install the new thermostat, and close the radiator drains, making sure the radiator has completely drained. Fill with new 50/50 antifreeze until the container is full, then check it later or the next day to see if it needs to be topped off.

**WARNING** THIS WORKED WAY TOO WELL
Leave it in for no more than a few minutes. During a heater core flush, I used this. br>After flushing the core with water, I added this product to soak in and hopefully remove any dexcool gunk that had built up. br>Well, it was winter, so it got dark quickly, so I decided to leave it on overnight in the hopes of breaking up the dexcool that had become stuck in the core. MISTAKE ON MY PART. REMEMBER NOT TO LEAVE IT IN OVERNIGHT. br>The next morning, I flushed it out, added some coolant, and drove it around for a while. The heat went from being non-existent to being extremely hot. amazing. br>When I pick up my young daughter the next day, she says, "I smell gas. " She detected a coolant leak from the heater core, rather than gas. I left this in for far too long, and I'm pretty sure it ate away to the point of causing a leak. I was fortunate enough to have some K-cups on hand. I had a seal lying around that I put in, and it appears to have stopped the leak for the time being. br>In conclusion, this product is effective. BUT DON'T LEAVE IT IN FOR AN EXTREMELY LONG PERIOD OF TIME. It was my error, not the product's, that caused the problem.

Calcium has a negligible impact
I bought a six-pack and used all six bottles, two at a time, for about 350 - 400 calories. Scale deposits in a radiator can be removed at a rate of 400 miles per session. After about 1000 miles and effectively giving this cleaner three chances to do the job, the deposits had little effect. During the first flush, it appeared to remove some dark material from the system, but it does not work on calcium (lime scale) as advertised. From a company whose entire business revolves around cooling systems, I would expect more. It's possible that if I buy another 18 bottles and use them for another 3000 miles, the calcium will be removed. The photo on the left is the original, while the photo on the right is after 1k miles and most likely 25-plus miles. Running for 30 hours.
Allow the engine to overheat overnight with distilled nitrate
Although I dislike prestone, citri acid is an exception. A foush solution diluted to 100k in distilled water and left to sit overnight cleans effectively. Some vehicles may not be suitable for this, but most, if not all, will suffice. I emphasize that it must be diluted in distilled water. People who brag about how it cleared garbage when they dumped in coolant are a bunch of knuckleheads. You can make a sludge by mixing any random garbage with your coolant. Drain and rinse the radiator with distilled water until the drain fluid is clear. Then take advantage of it. Then flush with distilled son several times to ensure that nothing is left behind and that the new coolant is mixed properly.

The heater core was replaced, as well as the thermostat, which had become stuck open
My 20-year-old SUV's heat was restored thanks to this miracle product. I've replaced the coolant on a regular basis, but I've never performed a chemical flush. At only 105 degrees Fahrenheit, the heater in my 20-year-old SUV was lukewarm. Warming up the SUV took a long time. The temperature of the coolant was also slightly below normal. It appears that I have a thermostat that is stuck open. I wanted to replace the thermostat and flush the heater core, but the heater core hoses and thermostat were in inaccessible places. Before taking it to the mechanic, I thought I'd give Prestone a shot. I poured a bottle into the reservoir and then ran around with the heat set to maximum for three days. Although the heat had improved, it was still not up to par. I drained the coolant. Fill to approximately 65% of capacity and add another bottle of Prestone. I ran for an hour with the heat turned up to its highest setting. It resulted in a significant increase. The temperature inside the dash vent has risen to a scorching 154 degrees Fahrenheit. The coolant temperature reading has returned to normal, indicating that the stuck open thermostat has also been resolved.

When changing coolant, make sure to flush the system
Always. CLR will not work in a modern engine, but Prestone Flush can be used according to the Super Flush instructions. The short instructions are never followed by me. Before I use this flush with water extended time frame, I usually water flush it (except in the winter, when I'd leave Anti Freeze in). I'm telling you, there will be so much junk in your motor that you won't know what to do. It's fantastic! br>br>I received this after replacing the head gasket on a 2. You can imagine how Crusty the coolant system looks on a 0L DOHC with a plugged water port on the head/block in one spot. I've already flushed everything except the block, and I'll use Prestone Flush to make sure it doesn't re-plug the system, as I've done in the past with other cars. It could cost up to $1,200 to have a shop do it all, and I have no intention of ever repairing it again. So, as far as you're concerned, do it correctly. Delete everything from your computer. In the winter, better heat transfer means a hotter heater and fewer problems.

The seal on the water pump has been damaged
My water pump seal began to leak as a result of this stuff. It happened after I flushed the system and added the final 50/50 Preston mix. The water pump's weap hole has now developed a leak. This stuff messed up the shaft seal, resulting in a minor leak. To fix, it will be necessary to replace the water pump. That will be a money issue with my car. My system was so clean that there was no color change when I flushed it, so don't use this stuff if you've already drained it several times with distilled water and it's crystal clear. Just toss in the finishing touches.

It works fine, but it's not necessary if your coolant system is in good working order
If you haven't flushed your coolant in a while, it's probably time. Changing the coolant every two years, on the other hand, is a good idea. There's no sediment or rust to remove after three years of using the same product. This item is most likely unnecessary.
