Motorcraft RG630 Thermostat Seal Review

My analysis of this replacement seal revealed that it was significantly lower in quality than the original. The seal did not fit properly and continuously leaked coolant, causing frustration and extra work for my mechanic .While the price point may be appealing, the cost of constantly replacing the faulty seal is not worth it..

After trying this thermostat seal, my car’s engine cooling has improved significantly... The seal is sturdy and fit perfectly in my engine, preventing any leaks or overheating issues. While it may be a bit pricier compared to other brands, the long-term benefits make it worth the cost..

I used this when I replaced my thermostat on my 2012 Ford Mustang 3.7 liter V6 engine. It worked fantastic, no leaks and was very similar to the old gasket I replaced. Glad I replaced it as the old one was warped in the car since it was new. My car now has 100,000 km on it.
