My truck also bubbles after the engine has been shutoff. How does this rule out a bad HG?We have verified that 2 of them continue to bubble when the engine has been shut off for a couple minutes, suggesting that head gaskets or block compression leakage is not a likely culprit.
I've also noticed my lower radiator hose never gets hot. I drove it for around an hour today on the interstate, getting into boost, going uphill etc. Temp gauge reads normal around ~1/2 on the stock water gauge. I ordered a new Toyota thermostat and gasket to rule that out.
