The Ultimate Cooling System; Complete System Upgrade
#21
Aaron, I'll grab a picture for you in the next couple days, but I'm just running a like $50 adjustable fan controller. 30/40 amp relay in it running a switched ground, not switched power. I got the controller off of ebay, but I think it came from Jegs. It just has the radiator push in style thermometer on it. Some people seem not to like them, but I haven't had the first issue with it. I actually used some CPU heat sync thermal compound on it this most recent time. Easy to find at your local electronics store, but not necessary as I ran without any on the factory rad for a year or two.

They're not really important as vehicles went without them for decades until they were invented, and some vehicles (such as Toyota Tundras) still don't have them.
Important is a relative term as in decades past there was never a shortage of overheating engines. At least with a catch can as Lisa Bunch showed us we can reuse the liquid coolant that may be lost when your cap occasionally vents.
There are maintenance advantages, less things to leak/break with a simplified system and removing the reservoir may free up some space to store flammable fluids......

True reservoirs are not needed to simply fill the coolant systems on vehicles with a radiator cap. Many of us are too young or too old (memory gone) to remember or don't know most radiator filler necks didn't even have a nipple to attach an overflow. After a nipple and tube were added the first "reservoirs" were simply overflow containers (aptly called overflow tanks). The reservoir plumbing and cooling systems later allowed the overflowed coolant to be sucked back (recovered) into the cooling system as it cooled.

My Chevelle does NOT have an overflow, the hose leaves the cap section and drains right on the ground. Having an overflow does not really help with purging air either.

Here's my fan controller setup. I mounted the controller itself next to the battery and pushed the sensor in right next to the radiator inlet for the closest possible temperature readings. You're correct, they do indeed make one with a 1/4" NPT sensor. If this one ever dies I very well may go to that kind.
Pay no mind to my fan mounting. It's a little janky, but it works fine as long as it's not overtightened. Even added foam and a little RTV to guard againt friction wearing through the radiator.
That's the idea! Those Heineken cans are neat. Never seen them shaped like a keg. A real bummer they don't make a better beer!

Haha, as many American made/designed parts as I've got on this thing (including the engine) I could also use an American beer. Been thinking PBR, my favorite sh*t beer. Helps that I've got a few left in the garage. Might be a fun project today.
