The shop wasn't trying to get new Business, what happened was I stoped at a shop along my trip path because of a overheat and they said my antifreeze was way past due, they drained it and I watched, it was dirty and rusty, they changed it and I was on my way, ( in Oregon) I arrived in Vegas a week later and my water pump failed, and when they pulled it apart everything was rusty.
I had not changed the antifreeze in about 5 yrs or about 60k,
So my bad...( bad to about 1,200.00)
So I was thinking the waterless would prevent rust, but I'll stay with the normal stuff and change it when I should...
