Review on Beck Arnley 143-0865 Thermostat: Optimal temperature control for ultimate engine performance by Sam Anez

Leaking at the base of the small hose connector that goes to the PCV system. . Luckily, due to my suspicion of these cheap Chinese fakes, I kept my original case and was able to fix it. I will write them to the support people and see how they solve the problem. They claim to have a 12 month warranty, but their "Warranty" department has no contact information. If you've never changed it on this car, you'll need to remove the power steering pump to remove the housing and drain some coolant. If this is a big task for you, I would consider switching to another manufacturer.
