I took my 2004 Sierra to Hal, when I was at wits end. I had taken it to multiple different shops just for them to want to either throw parts at it, or they said there was nothing wrong with it. I smelled antifreeze, and had an overheating at idle issue.
Hal found that the radiator was 60% clogged, the heater hose connector was leaking, the radiator needed repair, and it needed a new thermostat. He fixed it all and did a power flush of the system and now the needle on the temp gauge doesn't move. It was an amazing price for everything they did, and Hal was 100% honest with me.
He showed me that there are still mechanics out there that care about you driving away with your vehicle with no worries. Instead of you being just another number.
