Best Practices When Using Irontite Coolant Additives

Irontite make three different coolant additive products all intended to compliment each other and provide the best results when used in combination. You can purchase these additives individually from most major automotive parts stores in North America.  You can also purchase a "3 pack" direct from the manufacturer from their website here or also available through Amazon.


The Most Powerful Flush Available

Industrial Strength Radiator, Coolant System and Fuel Tank Cleaner.

Loosens and removes rust, scales, grease, oil and sludge.

Cleans auto and heavy duty truck cooling systems.

How it works - It attacks the oxydation that forms on metals. That means it's safe for all metals. However, after enough time it will start to degrade soft materials like hoses and gaskets, so don't leave it sit in your system for long periods of time.  Follow the directions and all will be fine.

Ceramic Motor Seal

The Performance Enthusiast and Racer’s Choice

Permanently seals engine coolant system leaks.

Seals porous castings and improves heat dissipation for added power.

Seals head and intake gaskets, aluminum and cast iron, cylinder heads and blocks.

Added to radiator ONLY AFTER removing antifreeze.

How it works - This is a "sealing treatment". Your cooling system must be drained and then Ceramic Seal mixed with water put in place of your Antifreeze Mixture. While running at operating temp and circulating it forms a micro finish over all surfaces filling in metal pores and cracks and making the inside walls of your cooling system smooth as glass. The longer you treat the thicker the seal. After treatment you will remove the unused portion, and rinse several times with water. Then allow to air dry before adding your Antifreeze mixture back into the system. NOTE: Do NOT allow any of the mixture to get into anywhere oil is as it will harm bearing and friction surfaces of the engine.

All Weather Seal 

The Ultimate Fix 
 for Head Gasket, Radiator and Other Coolant system Leaks.

Easy to use – pour directly into the radiator.

Blends with coolant to permanently stop existing and future leaks.

Ideal for the most extreme weather conditions – Hot or Cold.

How it works - When mixed with the existing Antifreeze of your cooling system it dissolves to a micro-emulsion. Instant coffee mixed with water forms this same micro-emulsion. It means that it doesn't settle out and is so fine that it can't clog anything. All Weather Seal remains dormant like this until 2 conditions are met. 1) the solution must be at or near engine operating temperature and 2) it must encounter air.  When those two conditions are met, the solution begin to form a barrier much like a Beaver building a dam to plug the leak. This make All Weather Seal a very good product to fix an existing leak AND to patch any future leaks that might crop up.

Be sure to read and follow the instructions on each bottle.

Don’t over use. Estimate the proper amount of product for the size cooling system you  have. Adding extra amounts does not make Irontite “work better”.

Flush with water frequently between processes.  After using Thoro-Flush and again after  using Ceramic Motor Seal, it’s best to flush the cooling system with water.  Because no  cooling system can be completely drained, by flushing with water you further dilute the  remaining product and get your system better prepared for the next process.

Use protective materials and fender covers to keep any splashing or drips away from  chrome and painted surfaces.

Proper flushing may reveal more leaks than originally seen as hardened rust and sludge  are dislodged from potential leak areas. This is normal and will allow these steps to further permeate all areas for long lasting protection.
