There are a lot of factors affecting the quality and performance of products including tsats as we all know.

In theory, it should work as designed... but thats in theory and may not always work as designed. Thats why not same products perform the same. Variables include workmanship, material, installation, other components in the cooling system, etc.

As said, Dieseldiant has a pictorial on drilling holes to help adjsut the temp. I believe that one big factor (covered in a discussion in this forum) affecting cooling performance is the oem radiator vs aftermarket. Based on the performance of my 84D (aftermarket rad) vs my 85D (oem rad), I beleive that the oem rad does not cool as well. The cooling performance of the rad has a direct bearing to the engine temp. I don't think this means that the oem rad is no good. Its just the the non-oem maybe more efficient (more surface area?).

Of course the stat is a key element. The oem stat is designed to work with the other oem components in the engine.

my 2 cents
