If you have an older vehicle especially one with plastic on the sides of the radiator be prepared to be buying a new one. I was wanting to keep my 87 Ranger radiator because it was original and didn't leak at all. I knew the risk but went ahead with the flush. It worked really well. Follow the directions to the T. But the nearly 40yo radiator o-rings on the side tanks gave out. So I ordered a new aluminum one yay! It worked and I got a lot of crud out so I'd buy again. Review: Great stuff, saved my engine. - This stuff ate the junk out of the radiator of the car next to me, it's that good. I have a VW Jetta Diesel that had a mystery water leak for quite a while. The PO dumped an asinine amount of 'stop-leak' into it, trying to fix it, to no avail. When I bought it, the system was so plugged up, the heater wouldn't work and the thermostat was glued open. I tore into it and found the leak, the water pump o-ring, under the timing cover. The vanes on the water pump were covered in goo, you could see caked up crap in the passages behind it. I thought I'd be hunting for a new car, but decided to give this stuff a try on the recommendation of a friend. Mind you, this system was so plugged up, it barely held a gallon of coolant, and the fans were running almost constantly. I went a step beyond the instructions, I replaced the thermostats, and flushed the system as best as I could with hose water, then drained it with a suction pump. I then filled it as the instructions recommended, and topped it off with distilled water. After the first 15 minutes, the recommended time, the heater started to work. I let it go 30 minutes, twice the time it said on the instructions. The water in the reservior looked like mud at this point and I was concerned about it eating the seals and gaskets in my engine. It took over an hour to completely flush the system after using this and get clear water running out of it, at first, there was goo coming out in clumps, it looked like river mud. After it cooled down, I again used the suction pump to be sure it was drained, used a scope to inspect the radiator, it looked like a new one inside, then I refilled it. It took the full gallon and a half of coolant to refill. It's been running fine ever since, the fans hardy ever come on, even with the A/C running. ## Features - Powerful Cooling System Cleaner: Thoro-Flush effectively removes rust, scale, grease, oil, and sludge from your vehicle’s cooling system, restoring optimal coolant flow and preventing overheating. - Clears Gelled Dex-Cool: Specially designed to break down and remove gelled Dex-Cool antifreeze, Thoro-Flush restores proper coolant flow and prevents engine damage caused by clogged systems. - Compatible with Multiple Materials: Safe to use on cast iron, aluminum, brass, and plastic, Thoro-Flush is ideal for all types of engine cooling systems, ensuring thorough cleaning without damage. - Prevents Overheating and Blockages: Regular use of Thoro-Flush helps clear out debris that blocks coolant flow, improving temperature regulation and reducing the risk of overheating or cooling system failure. - Easy-to-Use Powder Formula: Simply add the concentrated Thoro-Flush powder to your cooling system for a quick and efficient flush.

It works best when it also is heated and under pressure like it would be when the vehicle is running at normal operating temperature. Leave the Thermostat in and turn on all heat to get circulation through the heater core. Wait for the vehicle to get to normal temp then start the clock and after the 12 min. turn off, let cool, and drain. Fill with clean water, run, turn off, let cool, drain. Repeat until clean water comes out. **Q: do you have to flush out or can you leave in?** A: It's a flush, so you must flush it out with water. If left in too long it will degrade non-metal components like hoses, and gaskets, so it is important to NOT leave it in. **Q: Will this remove stop leak and safe for the heater core and transmission coolers? i have a bmw x3** A: Regarding if it will remove "stop leak"; that is a big "maybe" because it depends on many things. It is "safe" for the heater core and transmission coolers as long as you follow the directions on the bottle. It is a very powerful cleaner so you do not want to overexpose any soft materials like hoses and gaskets. Especially if they are older hoses and gaskets. It does clean cooling systems and fuel systems "dishwasher clean" as a friend of mine likes to say. Rinse well after using. heat and pressure make it work even better, so leave the thermostat in. And start the clock after the car gets to operating temp. Then wait for the car to cool enough to safely remove the product and then rinse with water repeatedly until it comes out clean. **Q: will this help with cleaning the oil cooler on a 2005 ford power stroke coolant side is plugged** A: Just to point out that the bottle and advertising all state that it is designed to remove rust and corrosion. Nowhere does it say it will flush "stop leak" from the system. While there are many people who have been successful cleaning some brands of stop leak using Thoro-Flush, that doesn't mean it will work on every variety of stop leak product available for use. Expecting a chemical reaction to a stop leak product from a product designed to react to metal oxidation (rust and corrosion) is an unreasonable expectation I feel. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works great. *by J***N on July 25, 2026* Worked great but...

Their website says 10 mins run time in the direction video they have yet the bottle says 12 minutes. Be careful draining the hot coolant but the product works very well in my 25 year old jeep. Restored my heat from 90 at the vent to 135 degrees . ## Frequently Bought Together - Irontite Thoro-Flush Coolant System Cleaner - Removes Rust, Scale, Oil, Sludge & Gelled Dex-Cool - 16oz Powder - Cleans Cooling Systems, Restores Coolant Flow, Safe for Cast Iron, Aluminum & Plastic - Lisle 60800 Heater Core Backflush Tool with Air - Eastrans 10ft x 5/8" ID Clear Vinyl Tubing, Flexible Hybrid PVC Tubing Hose, Lightweight Plastic Tube UV Chemical Resistant Vinyl Hose, BPA Free and Non Toxic --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.mx/products/13185960-irontite-thoro-flush-coolant-system-cleaner-removes-rust-scale-oil](https://www.desertcart.mx/products/13185960-irontite-thoro-flush-coolant-system-cleaner-removes-rust-scale-oil) --- *Product available on Desertcart Mexico* *Store origin: MX* *Last updated: 2026-08-16*
