Some say it doesn’t matter what radiator you choose to purchase for your vehicle. When my radiator was installed it was complimented multiple times during installation…the quality and fit was mostly recognized and opinions agreed that the quality was indeed worth the cost.

It being an acdelco, it was exactly as I hoped. It fit like a glove and I appreciated the fact that the oil connectors were sent with plugs. Thumbs up folks !
