if our engine run at 82 celcius there no reason its start boiling when you turn it off its normal for temp to raise when you turn off the engine but to start boilling thats mean our temp is higher then 84 degre check our gauge manuelly check the temp with a thermometer directly in the radiator and compare with the gauge that mean the faster you go colder its get so the radiator does its job but what weird it goes up at lower speed so not enought air goes trough the radiator are you missing a front spoiller that redirect the air to the radiator if you raise the boots you gonna have to raise the cooling capaciter of the car check it out let me no. . pierre

hi jasso, I would recommend checking the water pump if you see no flow in the radiator. Make sure when you fill up the cooling system, that you fill it cold, and that the vent screw in the radiator is loose. fill system until fluid comes out the vent screw. tighten the screw, start the car and have someone run at 1500rpm and check for flow.also, make sure that you have your temp setting full hot and blower on middle speed so that you don't trap air in the heater core.

Change the radiator cap, it may be the wrong pressure rating which will cause the coolant to boil at a much lower temperature than designed.

Try replacing the thermostat first. If it's new with the head job then try removing it altogether and see if that helps. New ones can go bad. Make sure it is installed with the coil down in the engine.
Is there any chance that silicone or form-a-gasket was used in the rebuild especially around a water jacket? Silicone can break off after the part is tightened and could be plugging a water passage.
When you redid the head was there a choice of more than one head gasket and did you compare the new with the old to be sure it was an exact duplicate? I would be extremely suspicious of either the wro ng head gasket or it being up side down.Either of these could block water passages and create your problem. Hope this helps.
