The reasons to buy the fittings are clear to me. 1) Time is money and having to carfully take the stock ones out costs more in terms of time. 2) lets say you do damage one of the stock fittings getting it out because sometimes you do find the one that is very well glued in. How long do you wait for the replacememt to arrive... Again time is money.


For me it was welding all the way, pinning IMHO is a futile procedure.

I can't vote twice, but I experienced a catastrophic coolant pipe failure on the following car during a test drive - on the first pull up a fwy onramp.

Oh man, how did the seller react? You break it, you buy it?

Seller was fortunately a large dealership. On the contrary, they were very apologetic. Catastrophic in the sense that all coolant was lost in a blink. Car still ran of course.

Good thing she let lose during the test drive and not after a purchase, since this was during the peak of summer, at a dealership about 400 miles away. I happen to be passing through while on vacation. There were other things, mileage included, that I would have passed on that particular vehicle anyways.

This first hand experience encouraged me to pin the lines on my now current car, as I surely did not want to experience it again.
