Mother had a 2008 Buick Century that we might still have had it not been for DexCool. It had the 3100 (?) V6 engine. Often the engine would just overheat some, which caused knocking. Turns out the coolant looked like and was the consistency of Metamucil. The dealer several times replaced the Dexcool but there was still that overheating. Buick was finally traded in on a Chevy Malibu that seems to have DexCool too but not any trouble. GM must have solved the problems by then.
I understand that the DexCool trouble occurs should the coolant be exposed to air, as might happen if you remove the radiator cap. In the case of your truck, maybe that did not happen and as long as no exposure to air, you may be fine. |

The Asstec still has the original at 122,000 miles. Zero problems. |

I've been told by many mechanics that the orange stuff is garbage and you need to flush it more often than it says you need to to avoid the sludge. They've said you can change back to the green but you must flush the whole system very thoroughly to get all the orange out first before filling with the green.
