Hi all,
Long time lurker, first time poster...I drive a 2017 MT Toyota 86
I was doing an oil change and everything seemed to be going fine, until I forgot to use a piece of timber between the front jack position of the car and the jack. It seemed as I was letting it down it slipped for the last bit and dropped maybe 10cm. I think when the jack slipped it went forward and might have damaged something...Stupid of me to not do the most important part right (securely jack the car)
The issue I'm experiencing now is that the thermostat seems to be broken.. I'm thinking maybe this is due to the force of falling that 10cm and possibly the jack slipping forward to the area the header plate is...
The reason I say thermostat is because the following things are occurring:
- Fans for radiator only switch on if I turn on the air conditioning
- when idling
without the a/c on the coolant temperature creeps up (I read through this thread -
https://www.ft86club.com/forums/showthread.php?t=76948) thus, idling, I let it climb all the way till 101C/214F before I turned on the a/c to cool it down) - the fans never cycled on/off
- Also upon normal start up I notice the coolant temperature takes long than usual to heat up. This to me is also indicating thermostat. As the valve should only open from 90C or something like that. But instead its "broken" open and the the coolant is constantly flowing and when I drive and the wind flows through the radiator (fans still not on) the engine coolant dips to around 88C (prior to this whole situation it would stay at 90C pretty solidly regardless of idling/driving -and then only after constantly shifting at redline on hot days, it would climb to a max of 92C/198F meanwhile the oil would be at 109C/228F) The service manual details how the thermostat should restrict flow till 86 to 90°C (187 to 194°F) then cycle fans once it reads at 95°C (203°F)

- the "idiot proof" radiator gauge shows the progres of the coolant getting warmer as I start-up and drive, so this tells me the coolant sensor is working (also I'm getting an accurate reading in TorquePro)
I use 5w30 oil cause Australia is hot af. All the temperature readings came off Torque Pro app
Being a newb to all this I'm just wondering if it is possible I have missed something and it is not infact the thermostat?
