Reviewer: Perfect replacement

I discovered my radiator expansion tank was crumbling from old age. Thought I'd have a hard time finding replacement but within minutes had located it on PartsGeek, within days I had it and in minutes installed it. It was an identical replacement. This is how an online shopping experience is supposed to work. Thanks.
