Premixed Antifreeze brand?

[DaveNW]

So I called the place where I bought the car last year. They're friends of mine, and I trust them to tell me the truth.

They checked their records, and saw that they'd replaced both the water pump and thermostat before I got it. They said that means they replaced the coolant, and they used (drum roll please) Porsche OEM coolant! It's a good thing I asked before I did anything. Because I don't have tools or experience with this sort of thing, I took the car to them today. They're going to do a flush and fill (with Porsche OEM coolant) and do a pressure test.

When I pulled out of the garage, I noticed a tiny spot on the floor with a clear, slightly odorous fluid. It felt kind of slick, but not like oil. This is new, so I'm going to think it's coolant. So I may have a small leak.

Those of you who are better at this than me: If there is a small leak, will a pressure test pick it up? If not, is there an easy way to figure out where a leak is coming from?

Sounds good so far. Pressure testing is to detect small leakage so they could tell for sure to diagnose your coolant loss. Good luck!

Ask them what brand of water pump. The aftermarket pumps are pretty much garbage with the exception of Pierburg. Porsche factory is your best bet on that one too. Also ask if they installed a standard temp sensor or low temp sensor. Generally a good upgrade is the low temp version.

So I picked up the Boxster today. The shop did a pressure test, and everything is fine. Strong pressure, no leaks. The water pump and all coolant lines are dry, no leaks. So that's all good, I think.

They topped things up with Porsche OEM coolant, and gave me the rest of the gallon so I'll have some if needed. I've got the car safely back in the garage with cardboard under it, so I can see where any leaks may happen while I'm out of town for the next two weeks. Hopefully, no surprises.

I'll ask them about the brand of water pump they used, and the temperature sensor.

Thanks for the help, guys. I appreciate the education.
