"My BMW is running awesome. The acceleration is back and the coolant level is staying right where it needs to be."
-Chris, BMW 3 Series (testimonial left Jul 10, 2023)

"It took maybe an hour to do the whole process and Presto! everything is fine. This is my third day now driving the truck -- no smoke no running hot. Everything is perfect."
-Jessie, 1996 GMC 5.7 (testimonial left Dec 13, 2021)

"I have a 1997 Lincoln Town Car with 33k miles and it started running hot and using coolant. I used several products that claimed would fix the problem. They would work for a short time but after a few weeks I’d notice the coolant disappearing again. I thought it was over and was planning to suck it up and have the head gasket replaced but found Thermaweld. Read the reviews, watched the videos and thought…maybe. I ordered and [technical support was] a phone call away when I applied the product. I followed their directions and it has COMPLETELY sealed up the coolant leak. I have taken the Lincoln on a road trip and no issues, no coolant loss and no overheating. Thermaweld is the REAL DEAL! Finally a product that does what it says with REAL PEOPLE following up with you. THANK YOU!"
