Thanks | | |

Double check the timing, valve adjust etc. Also, dont run straight coolant, just enough to prevent corrosion. Straight water will cool better than coolant. Also, your temp gauge may be off as well, don't forget to run a thermostat. | | |

Doesn't matter how hot or cold outside, always within a coupe of degrees of that. Also has the stock radiator cap, which is non-pressurized. | | |

Numerous checks with thermoter in radiater said 180. 180 thermostat, pickup for the capilary tube is close to the head and I assume it is a little hotter there. Ck and see what your true water temp is. I had reversed flushed the entire cooling system and radiator twice. Truck never boiled over. I bottle of water wetter will lower you temp about 5-7 degress also. | | |
