Pentosin coolant v. Porsche coolant - 986 Forum - The Community for Porsche Boxster & Cayman Owners

I was quoted in one of the posts, but I refilled my car with OEM stuff when I changed to the LN low temp t-stat. Even though my shop uses Pentosin, I just wanted the OEM stuff as the difference in price was negligible.

So I haven't helped your cause...

They also swear by Royal Purple, but that will cause a whole other uproar.

I recently replaced my coolant (Peak extended life) and the procedure for burping the air was a little scary. It took a long time to purge the air and things got a little too hot for my comfort zone...220+ but all ended well. This is definitely not like flushing the Toyota. Follow the instructions carefully.

Thanks for the feedback. I just ordered Pentosin for $12/gallon... added to my list of other maintenance to do in the next couple of weeks. Sweeeet.

If my car blows up, I'm blaming you, JFP in PA and your red font color.

"the procedure for burping the air was a little scary"

When I changed mine, I followed the procedure on Pedro's site initially. I then drove the car to my WI home (approx 125 miles) with the bleeder valve open. Next morning when cool, I topped it off and closed the valve and it's been fine since.

Yes. After my initial concern I talked to Brad Roberts. He said "just leave the bail open and drive it around. Some cup cars never close the bail." That's what I did and after three days or so the coolant level was stable. It just freaked me during the initial air purge watching the temp climb. I know what happens if it pegs 250F... Hello Jake, have you got a motor for me?

After running a fleet of Toyotas for 30 years it just startled me how long it took to purge the air. All went according to plan though.

did you buy this locally or on the net? I am having trouble finding any coolant besides at the dealer.

Call Suncoast or Sunset Porsche. Both great dealers should have the lowest price.

On Suncoast's web store...

Shipping kills the price savings there. The stealership is around $30 a gallon

Ah - forgot to follow up on this one.

The "gallon" for $12 that was listed on PartsTrain.com was actually 1.5 liters (about 1/3 gallon).

I brought this mistake to their attention and returned the Pentosin, but they didn't care or make any kind of apology or offer any way to make up for their error... great customer service there. When I asked to speak with a manager, they hung up on me. I called back again, and they hung up on me a second time.

They still haven't fixed the error on their website where it clearly states "1 Gallon, 1 Gallon Size Container".

Anyway, if you don't go the auto store route, just get the Porsche stuff. It's cheaper than Pentosin.

it seems like that's the route i will be taking. I just find it silly to pay for the name on the outside of the container when it can be had much cheaper.
