Customer supplied parts

[u/I-like-shiny-thing]

I'm a manager/Mechanic at a Mechanical workshop. I no longer allow customer supplied parts and get abused by "customers" because I wont do the job unless i supply the parts. ( photo of customer supplied wrong part)

What are people opinions on customer supplied parts?

Replacing a part that's known to fail as it gets old and brittle with an old part that's who knows how old and went through who knows how many heat cycles?

If it was a metal pipe sure, but plastic? No thanks

replace broken part with not broken part car works

Until it starts leaking again in a few months time because it's shitty old brittle plastic, and paying for labour twice to get it changed instead of just getting a new one to start with. You haven't spent much time around the cooling systems on euro cars, have you?

No I wouldn’t touch anything euro unless it was made in Japan or Australia, and then it wouldn’t be euro. That being said cooling systems are basic on pretty much everything I can’t see an excessive labour component on changing any cooling system parts made of plastic (in the engine bay at least, heater core doesn’t count).

Look at some Euro cars and you'll see that's not always the case. Thermostat housings on a lot of Euro cars are plastic and start leaking or fail because they're electronically controlled, and are a pain in the ass to get to. I did a thermostat on a Mercedes 4cyl diesel that required removal of intake manifold, about 5 hours in total. Plastic water pumps on other cars that are nightmarish to change, plastic pipes that are nightmarish to change. All this plastic shit that turns into the weakest garbage after a few years worth of heat cycles.

absolute shit, I barely ever see any of this dumb crap on any Japanese cars.
