A couple of tips I can remember right now. I used this tool to trim the fan. It’s actually very useful. And also, make sure you mark the polarity on the cable if you are cutting it. Read the post at the beginning.

This how it looks on my iPhone. I build an app for it. I’m reading all the data using two arduinos and one obd2 controller. With the Camaro fan also. 👍👍

Hello everyone! Just to share my experience, at 115f ambiente, and driving at 70 miles per hours with the AC on, it will make a difference on the ECT temp and also the air coming out the AC. With the fan off on those conditions, the ect temp will probably go to 220 but the ac will be impacted...

Hi. I would like to take this approach. Can you tell me the steps you take in order to accomplish this project?

Hello everyone. I just want to give you an update on the setup I have using the arduino. My temperatures reading are from 199 F to 205 f while driving below 50 miles per hour with AC on. Driving at 65 miles or more temp will be close to 210 F with ac on. The max amps reading I got so far is...

here is the code for reference // —- Pin Definitions —- const int FAN_PWM_PIN = 9; // Digital pin for fan PWM control const int NTC_ANALOG_PIN = A1; // Analog pin for NTC thermistor input // —- Fan Speed Parameters —- const int PWM_MIN_SPEED = 38; // 15% duty cycle (base speed) const int...

All this was accomplished with the information already provided on this post of course.

I did a recap using Google AI. This is the tool I used for coding and do research since I am not an expert at coding.I used an Arduino R4 wifi, same NTC controller, a fixed resistor for voltage divider (440 ohms) and this MOSFET...

Hello, everyone. I manage to swap the controller with an arduino. I will post some information but it’s working great. The most important is having fully control on fan speeds.

Thank you for the feed back. Not sure why but fan starts slower using this setup, can’t tell why. Been driving around around 91f (ambient temperature) and temp is at 199. I can’t hear that ramp using the 130/190 for example. Using the 160/200 the fan speeds faster. Ina bout a week we will a...

Hello everyone, just want to share something I did following this setup mentioned in this post. I used two diodes connected in serial. Why I did that, just to find out if there was away to have the fan on but be able to have the fan speeding slower to higher and see if there is any difference...

Any recommendations on what pump to use? I know I will need one very soon. Jeep tj 2004 4.0

Yeah, I can only see people recommend from other post is the Delphi one. The other store brands doesn’t look promising.
