Went too Dougherty in West Chester Pa for inspection/emissions ( I'm exempt on emissions ) and wanted to say again what a nice clean shop they have. Had a couple nice GT3s set up for track, three cup cars, a really cool 993 race car, super clean 328GTS and a hand full of other 70s 911s. My only complaint is the traffic and 85mi round trip.

 

You get you're windows tinted when you were there?

 

I wanted to but ditty took the last roll lol. They did quote me between 350-400 for radiator flush/coolant, the lazy me wants to let them do it.

 

So you're not buying into the "lifetime coolant"? The burping seems to be the technical side with having the right tools. If you do dyi I'd flush it out with water after you drain it then refill the coolant.

 

Yea I have the tools and have done it before just would be nice to not have to fool with it. I read an article recently about checking conductivity of coolant and even 10 year old coolant was way below limits? Who knows lol.
