just bought a skyline r33 gtst a few days ago
want to know why its overheating
it started overheating today because the previous guy put techaloy 60 in, i filled it up with 90, the reservoir was at full mark, and when it overheated it went about 3-4cm above the full mark and the radiator had barely any coolant in it, n the coolant in the reservoir was boiling for about 10-15 mins...
so i did a coolant flush, put techaloy performance 100 in
but after about 30-45min drive it started overheating, the coolant in the reservoir was almost empty (was up to the full line before) but the radiator still had the right amount of coolant in it...
i cant figure out the problem, the cap seems alright, the thermo was opening because it was able to bleed the coolant
p.s. when it overheats it only ever got to the white line iust before it hit the hot mark (the white line is bout 5mm before the hot line), so it never hit hot
anyone got any ideas? much appreciated
