Both of these parts were excellent. They were indistinguishable from the original Mercedes parts.they work perfectly and now in my car I have heat again. For anyone planning to do this job is extremely difficult to get to the lower bolt of the thermostat. don't even try to save the old hose cut it off immediately. Get a thermostat on then boil the hose in hot water. Then you will be able to partially get it on,next take a large turkey baster and get a really hot again by squirting water on it and then you will be able to wiggle it on. This job took me five hours. Some people say if you take the oil dipstick tube out it will help. I can get my dipstick to wiggle after unbolted but I was never able to get it out.
