How to cool a cs4 or cs4-i, even better than just bleeding the air pocket.
- Thread starter 1900colt

Will add this inline to confirm coolant flow.
The fans are not very powerful but being the head temperature is so low I have no need
to improve. I’m going to add a water temperature probe also.
SS, if you’re referring to my Gx the external fans don’t add any noise above the unit itself.

I just rotated mine and all I have to say is wow. I must have had an air pocket because I’m running like 20+ degrees cooler now.

@blackdog899... I noticed your coolant in the external radiator was green... Is that PC coolant? or an automotive Coolant?

If I have to change coolant I’m going to auto antifreeze though as the pc coolant was $20 for a quart

Dang Blackdog, looking good! you could enter that into a contest-Pimp my Pressor and for sure a winner.

Got some new parts to go on… haha .
But please don’t put me in the category of worrying about the life span of my compressors. I was keeping busy while immobile during the winter. Another poster had a computer fan and radiator and I just thought it was a cool haa project.
Mostly cheap Aliexpress parts. So now I’m adding a larger reservoir and pump.

Rotated my CS4-i today. Took me longer than 20 minutes and I spilled way more than a teaspoon of coolant.
While running the pump checking for leaks I rotated the assembly right and left. Was surprised to see a lot of air bubbles in the top tube from the radiator to the holding tank when rotating. Oddly in one direction only. My fan power cable was long enough so I did not have to reposition the fan on the radiator. I did have a minor wire/connector clearance issue with the connections on the bottom of the internal power supply. Had to bend the connection lugs on the power supply circuit board to gain clearance.
Have not used the compressor other than in my air conditioned shop to fill a Ghost so water temp had not gone above ~97 degrees f. Gun is full right now so I will have to go out shooting so I can fill it again to check post mod water temp.

just did the change to mine. super easy to do. my fan had plenty of wire to not need to flip it like some others. Temps are definitely lower...guess time will tell how well it works....

What were your before and after temperatures? Just curious. I have not used mine since I did the mod so do not have an after temp yet.

So long as PC coolant works and is ok for the system it's a small price to pay if your compressor ever leaks coolant all over the place. You'll be glad it's non toxic PC coolant and not nasty toxic automotive antifreeze. How does it work? If PC coolant works well, is non toxic and prevents corrosion I'd go with it.

I was curious about the ingredients of PC coolant. Here is an AI response I got on one query:
PC coolant typically consists of a base fluid, which is often water, mixed with additives like glycols and corrosion inhibitors. Distilled or deionized water is frequently used as the base fluid. Additives may include ethylene glycol or propylene glycol for freezing point protection, biocides to prevent microbial growth, and corrosion inhibitors to protect the cooling system components.
Here's a more detailed breakdown:

While water alone can be used, it's often preferred in its distilled or deionized form to minimize mineral buildup and potential corrosion.
- Glycols:

Glycols are commonly used in PC coolants as they lower the freezing point of water and also have a good capacity for heat transfer, according to Titan Rig. Ethylene glycol is commonly used in automotive antifreeze and is a major component in some PC coolants, says Chemical Safety Facts. Propylene glycol is another option, and some PC coolants are based on it, as reported by Reddit.

So go to Amazon and take a look at XSPC Pure Distilled Concentrate PC Coolant, 150ml. Check the Label and MSDS at the address on the back of the bottle. Makes 1000ML for 20 bucks.

The MSDS says very little other than it is 98 to 100% distilled water. What I want to know is comprises the up to 2% other stuff. Since it has a very low conductivity I have to assume that the up to 2% isn't salts in solution.

I’m adding a external coolant tank to my Gx cs4i
Said hell with it and bought automotive premix
