My engine has the almost identical thermostat housing ( both made in Taiwan )and I couldn't get it to stop leaking around the base. So I ordered this new housing and installed it with a thicker gasket than came with it with permatex and it leaked worse than my original. Upon inspection I found that the bases on both housings were not flat, if you put the on a flat plate they would rock back and forth. I took my old one and using a statioary belt sander simply sanded the base flat, it no longer leaks. I returned the new one and of course had to pay the shipping again.
