Dev's Thoughts on Experiences, Projects and Lessons

I took Rhino out for a drive today to get some lunch. As the car was not warmed up properly yet, I decided to let the car idle while I packed, and 10 mins later, I noticed that the temperature was idling at about 90c. I checked the engine bay if the fan was running and it wasn't. So I decided to check and look around if there is any clue that could be causing this. I noticed that the cable that connects to the aux fan resistor or aux fan ballast seems to have had its insulation melted. This is strange as the insulation was corrected not too long ago. I called the wireman to share my observation and he mentioned that the issue could have been a bad resistor or aux fan that was drawing too much current. But till this is checked in person, we will not know for sure. I called the AC guy after that to get some opinion, what he shared was new learning for the day: The Aux fan will trigger at a low speed once the AC pressure reaches a certain level When the freon level is low, the pressur...

It looks like my journey with the vibration and sound may not conclude just yet. There is a distinct noise that comes up when the transmission is in D and it comes up at about 1800rpm. I have no clue at the moment what this is. When the car is Neutral and revved to 1800 - 2500, this issue is not seen. So that concludes that this only happens when the car is in drive and has something to do with the transmission/drivetrain. The strange thing is, as I work on refreshing old and worn-out parts, all of these symptoms are coming up. I remember when the rear absorbers (link: here ) were replaced, the ball joint bush went faulty a few hours later that prompted an Adhoc fix. Could there be a link with regards to the changes in dynamic of the ride height, flexibility, movement against the drivetrain that is bringing all these noises out? Strangely, I did put a hot tip on changing some new parts that would potentially introduce new noises. When driving at 80km/h, there is a particular vibration ...
