However, they eventually came to see me to have their coolant leak repair done properly. Coolant Leak Repair Additive ResultsĪs I mentioned, some of my customers poured this stuff in and received mixed results. In the next section I'll talk about what I've seen when replacing the leaking parts for the customer.
Whether or not you want to believe these product stories is up to you. When you start reading through the reviews most of them start out saying they remained skeptical, but became pleasantly surprised. With that said, if you go to the web page they say it works in these areas. And this prevents the product from hardening to seal the leak. I've also never seen it work on a leaky water pump situation, because the pump often leaks from the input shaft seal.Ī worn out, water pump allows the spinning shaft to move around. I'm saying I haven’t seen an additive permanently fix a head gasket. With that said, I have run into a few people that say they’ve seen success in these areas. This is really hard for me to believe and I've never seen any product work on a blown head gasket, because of the high combustion chamber temperatures and pressure. In addition, the product makes claims about solving cylinder head gasket failures and water pump leaks. This stops them from blocking the larger coolant passages throughout the engine, heater core and radiator. The product description goes on to explain that the particles bond together when they find the leak. The idea is these particles find the leak and then harden to stop it. The claim remains that the formulation includes microfibers containing ceramic and copper particles. Therefore, I'm just repeating the propaganda dispersed on their product page. Whenever you look at the ingredients of these specialized formulas you really won't find any explanation of what's inside.

I also do not recommend the installation of this additive without a full understanding of it. Although I'm writing an article about this product, let me be clear that I have never poured it in myself. This is highly unusual for any fluid in the stop leak category. However, the K-Seal product has more than 670 reviews and an average rating of four stars at the time of this writing. Generally speaking, stop leak products don't produce excellent reviews. The reason I'm writing about the K-seal coolant leak repair additive is because of the reviews on the Amazon website.
Nevertheless, instead of taking their cars to me, a trusted mechanic, they find themselves trying low-cost and temporary solutions. In fact, this is the reason why I started the fix my old website. These people become stuck in automobiles far longer than expected. Although my customers like me, many of them are in difficult financial positions. The answer is although I haven't installed it myself, I've seen vehicles that tried it. So why am I writing about a coolant stop leak product when I never actually poured this stuff into a cooling system? If the heater core drips on the passenger side floor I believe in replacing the heater core. For me coolant leak repair means replacing parts.
