It works great 2001 gmc work van. Gasket went out and dumped coolant, hour away from home. Sealed it up and cooling system is fine. Need to make sure you drive it after you wait the 15 min.

A real difference. My goal is to get our Chevy minivan to 250,000 miles. The transmission is the “critical path” item. I noticed a significant difference after adding this product recently (in late Spring) to our vehicle. The transmission was slipping at almost every stop. Now it shifts much more smoothly.
