all new hoses, i have put a 185 thermostat in it, it had a 195 last time but canadian winter call for that sometimes, i bought the coolant pre mixed, i did test it and it was good from -40 to 120 degrees c. i made sure to run the car and when the thermostat opened up i did top off the rad so no air locks. my fan kicks in when it's sapost to and the water pump is working fine( 1 lees thing to change, thank god).this over heating thing dosn't happen every time(2 out of 5 times)

so i will try the heatercore flush and see what happens from there.
