So I decided to dump the Propylene glycol coolant I put in and go back to ethylene glycol.
I did the usual remove the bung from the radiator flush it out, I also took the heater hose off the fitting on top of the engine and flush through there as well.
Whilst flushing it out coolant was coming out of the stat housing port where the heater hose connects to and was pouring onto the alternator before dropping to the ground.
Thought nothing of it, when I was done I hosed the entire area out.
I then noticed to what I thought it was smoke coming from the alternator. I could hear a faint sizzling sound also. The smoke had no odour apart from the slightest smell of coolant, but that could have been remnants of the washed off coolant. The smoke to me actually looked like vapour though.
Not sure on what was going on I disconnected the battery and all was good. Reconnecting the battery it came back.
So I started the Patrol up and ran it for a good ten minutes. As usual, upon start up for the first few minutes the alternator charged at 12v, then it kicks in and charges per normal, not sure why but it’s always done this.
I turned off the motor and all is good. No sizzling sound, no smoke/ vapour.
My thought is maybe a chemical reaction from the coolant and components inside the alternator???? But when 12v is cut off nothing happened. So maybe not.
If I knew how to upload a video on YouTube I would but tried to work that out and my head just hurt. lol
Any suggestions on what had just happened? More so. Why?
Cheers
