I understand the flow of the cooling system, but with the extremely small hole in the coolant filter AND the extremely small size of the coolant filter return line there's no way you're going to get 8* coolant drop with a small cooler. Sorry, but I just don't buy it. There are actually 3 feed lines going into the Degas bottle and by the time the coolant from your little cooler goes into the Degas bottle and mixes with the coolant from the other two and makes it's way to the temp sensor it's physically impossible for an 8* difference. Something else is wrong.

One other thing needs to be pointed out here: This very small amount of water is being dumped at the same location that the water comes OUT of the motor BEFORE it goes through the radiator. If you remove the cap and watch flow that comes out of that pipe you'll find that with the thermostat open there is uncooled water running through that pipe at all times anyway. Hot on hot as you put it.

clane,

You have effectively created another cooling loop in your cooling system... I have to agree with NPCCPARTSMAN 8 degrees seams like a lot... either way doing so is pointless. If you want to run cooler temps change your thermostat it will to the same thing...

No. The Degas bottle is just that. Maybe it should be typed DEE gas as in to remove gas?

I agree with ehgeeray and NP 8 about the ability of your cooler dropping temps any measurable amt. For what it's worth,the engine is desighned to operate at and have maxium longivity at + - 195*. If temps normaly remain -10 or +10 outside that,imo,changing the t-stat to a hotter/cooler t-stat will cause far more trouble than it will remidy. A new t-stat may often cure temp problems on any engine but only if it is the OE reccomended degree.
