360 coolant /fans gremlins

Hey guys so finally my 2000 360 is running a dream sounds perfect drives amazing .. went for a small 5-10km drive down the highway few side streets ..got the 430 muffler on sounds insane .. soon as I got home I noticed coolant coming out on the tray and floor at least 600ml-1lt when I moved the car in to park checked the temp was just over a 100 no thermo fans were on either when driving it the temp was perfect everything was ... turned it off before it got worse few hours later checked the resovior was a inch under so still very full .. let it sit overnight then came back bout 2pm started it waited for it to heat up took some time finally got up gave it couple light revs the temp needle went down quickly then up slowish near 100 fans kick on drops back down .. i turned it off to chill and could hear little bubbling sound from the resovior.. came back checked coolant was still full no drop ... the caps new to / cars running best its ever run / no white smoke / no coolant level drop in the resovior .. coolant was flushed on service I don’t understand why the fans didn’t switch on when I got home after a good drive plenty revs and fun then today was just sitting still running fans kicked in no coolant leak ????

 

The temp on the gauge was over 100 bout 120 say.. not in the red but heading there just jumped as soon as it got in my garage .. my fans usually kick in bout 90-100 .. thing that ****s me is it’s the best it’s ever driven now .. what about hooking up a switch in the cabin to manual turn the fans on ??

 

thanks heaps man for that I will give it a go tonight I was having the time of my life the other night just got my 430 muffler on the new carbon seats .. what a difference feels like a new car but still learning these little glitches and gremlins that are happening at the moment will report back with the outcome I was all stressing I blew a head gasket

 

will get down tonight let my baby run and check them radiator see if it’s got some heat .. was just weird after a big drive it did it and the fans didn’t kick on but when sitting in the garage running next day fans come on .. will start there tho and let you know how it goes ..

 

Hey man not sure how it was done but I think it was done poorly it never had the problem before ... how ever what you and 24000 rpm said make sense if the radiator wasn’t getting the signal cause a air blockage or thermostat stuck closed after the long drive the resovior was getting hot hence the leaking out the overflow .. the following day when I tested to see if the fans kicked on on they went and the temp stayed good .. just had some light bubbling noise in the resovior .. how ever coolant levels there are still good even after such a big loss I am going to try again tomorrow give it a wash to .. as I say starts great no smoke runs like a dream best it’s been since I had it beside that

 

Ok boys so
Radiators get hot
Fans came on at 100

had to switch the car off move it turned it back on fans didn’t come back on car went over 100 coolant leaking out the resovior

 

Thanks man honestly was stressing hard cause one minute was fans on next minute overflow was out of control Ok so will check the coolant level tomorrow add some do your steps I really do appreciate you replying and helping I am not very good with typing stuff I get to excited lol

 

Hey man hope your well just a little update haven’t been able to drive much cause the lockdown so on .. I did some the methods you said to bleed it threw the resovior I seem to get both fans kicking on which is good I haven’t taken it for a huge drive cause worried going end up frying the engine lol... I did notice tonight tho going to get some petrol in it that the passenger side fan wasn’t as hot as drivers and I get a light bubbling noise from the resovior when it’s switched off after a drive .. caps new changed that seems to always have lots coolant to .. any idea what the bubbling noise would be ??

 

Thanks again man will give it a crack again I was thinking I hope it’s not my head gasget


That’s my worse fear lol
