how many hours will a shop charge you for a coolant flush and water refill and also a brake flush and top up?

Coolant is supposed to be lifetime, so no flush needed.
Brake fluid flush about $200-$300 USD

Tbred911

sure.

but how much and how long does it take to flush and refill?

I don't care what Porsche says there is no such thing as lifetime coolant. Be smart and change it every 3-5 years.

A couple hours I'd guess on the coolant question. The coolant drains out pretty quick. The time comes from drawing a vacuum on the cooling system and then filling the system air pocket free.

Still, I'd guess a couple of hours. But you'll have to call around.

Brake flush about the same, save the brake system doesn't get a vacuum but gets connected to a power bleeder that forces in fresh brake fluid while the tech walks around the car bleeding each brake caliper in turn.

Sincerely,

OK, I have Wayne's book on 101 projects and am looking to put in a center radiator. Step one is draining the coolant...and he points to the two large hose returns and says "disconnect the two large hoses..." Well, I'm very new at this and after pulling the snap connectors and looking to separate the metal pipe from the rubber hoses...I have the feeling I'm just digging myself in deep on something that isn't probably critical to adding the center radiator. Figure 3 on link below. http://www.pelicanparts.com/techarti...lant_Flush.htm

However--any tips on separating these hoses? And is it worth the pain at the end of the day? Coolant is very new after motor rebuild recently by a shop.

A newbie...

If you have an air compressor, you can do this method instead. No need to mess with the big hoses.

Excellence recommends a coolant flush and change every 2 years using a 50/50 mix of Porsche coolant and distilled water. Seeing how you should be doing a water pump every 4 years as scheduled maintenance also.

While I subscribe to a 4 years or so coolant drain (flushing not required) and a refill with Porsche antifreeze/distilled water blend I can't subscribe to a 4 year water pump R&R with no evidence of any water pump issues. If I had followed that schedule my 02 Boxster would have by now had 3 going on 4 water pumps vs. just the one which I had replaced at 172K miles. The replacement has over 110K miles on it.

(The Turbo's water pump lasted around 115K miles and 10 years.)

FYI - My shop wants to charge me an hour labor to drain and fill or two hours to flush and fill. For brakes, an hour labor. Hourly rate is $150. Plus consumables obviously.

Ahsai--thank you for the great tips and the tool pics. Both are very helpful to us newbies. I'm going to leave the heater cores alone....it's great to have such a clear explanation and measures of each segment's coolant. Tom

my indy charges $100 for a brake flush. It is a simple job with the right equipment.

I agree and how big a job is it anyway. Easy DIY work and maybe if this was done, Just maybe less coolants tanks would split for unknown reasons. My coolant tank is original but my coolant is NOT.
