daytona74 Posted November 6, 2023 Report Share Posted November 6, 2023 Hi all, new member of the club after purchasing a 2005 987. She is beautiful and looking to purchase antifreeze top up. Where do peeps go to, to purchase and does it need to be ‘Porsche’ related? Just want to look after it as best I can and get things right. Thank you 1 Quote Link to comment Share on other sites More sharing options...
greenman986s Posted November 6, 2023 Report Share Posted November 6, 2023 First question should be why do you need to top it up? Where's the coolant gone? 1 Quote Link to comment Share on other sites More sharing options...
daytona74 Posted November 6, 2023 Author Report Share Posted November 6, 2023 Hi, it’s just above the minimum and want to top it up. Quote Link to comment Share on other sites More sharing options...
iborguk Posted November 6, 2023 Report Share Posted November 6, 2023 (edited) Welcome. If it were mine and assuming it's got regular Porsche coolant in it (the coolant colour will be a clue i.e. pink) then I'd buy this from a Porsche Centre. Don't be afraid to ask for discount. https://www.design911.co.uk/p/coolant---antifreeze-1ltr-topup-bottle---long-life-5-year-red-00004330103-00004330147-00004330515/ Edited November 6, 2023 by iborguk 2 Quote Link to comment Share on other sites More sharing options...

Paul P Posted November 6, 2023 Report Share Posted November 6, 2023 I would imagine that such a small top up would be fine with de-ionised water. perhaps treat yourself to a tester. Figure out if what’s in there is in range and top up with water for now. Then monitor and see if you need to investigate a leak. 1 Quote Link to comment Share on other sites More sharing options...

There's nothing particularly special about coolant. As long as it's the right spec and the same type as what's already in there sling it in! 4 Quote Link to comment Share on other sites More sharing options...

Agree, I use this from Halfords, you can stick your reg. number in and it will point you to the correct coolant.

½cwt Posted November 7, 2023 Report Share Posted November 7, 2023 (edited) The alarm bell can be the reason for it needing a top up. The front coolant pipe joints corrode and then start to leak. Not an easy or cheap thing to fix unfortunately. As for what you use, these car hold 18 to 22 litres of coolant depending on which engine (the S had an extra rad in the front), so a 50:50 mixture covers you down to -36°C and a 33:66 mix down to -20°C, so adding a litre of water (deionised preferably) to a 50:50 mix is not going to give you a problem unless it has been done lots of times already because there is a leak.... Something like the Comma listed above is fine, or any decent brand OAT (orange) tye anti-freeze will be fine. In this case the Porsche stuff is a fair price.

Hoster987 Posted November 10, 2023 Report Share Posted November 10, 2023 First of all, if you are just above the min then nothing to worry about. My 2005 987 was below MIN (which I just noticed since the purchase back in Apr but no cooling / temp issues) and filled with Valvoline / Zerex G40 which seems to be the go-to, pink coolant here in the US (and easily available on Amazon). Just FYI, although mine was well below MIN, I only had to use about half-quart to bring the level just above MIN (where the letter MIN is). 2 Quote Link to comment Share on other sites More sharing options...

Boxsters don’t use consume coolant and are generally filled upto just below max when refilled by a garage. If it’s got to the min level then there’s a leak and something to worry about. Yours is clearly leaking somewhere to get below min, so I’d fill it up to max while I investigated the leak. Top trouble spots are water pump, from crossover pipes and expansion tank. Leaving it that low when you have a leak is risky. Quote Link to comment Share on other sites More sharing options...

As I acquired the vehicle back in April, this was the first time I actually noticed the coolant leval (as i was doing a few other things like oil / tranny fluid changes, new exhaust tips, CDR24 fix, etc.). The previous owner repalced the thermostat / water pump 12 year ago (but only 14000 miles in 12 years), and I suspect those guys may have "under filled" as I have not seen any leaks but will monitor for sure due to its age.

Boxer boy Posted November 15, 2023 Report Share Posted November 15, 2023 Whip the front wheels off .Remove the liners ( easy ) and closely inspect the cross over pipe connections. Report back on state of dryness or dampness . Until you have a handle of those joints further speculation is futile . 1 Quote Link to comment Share on other sites More sharing options...
Menoporsche Posted November 16, 2023 Report Share Posted November 16, 2023 Possibly also corrosion at the bottom of the rads from rotting leaves. Though they usually get the condensers first. 1 Quote Link to comment Share on other sites More sharing options...

I have been thinking about removing the front bumper to further clean out junks (and maybe install a grill). Thanks! Quote Link to comment Share on other sites More sharing options...
Menoporsche Posted November 17, 2023 Report Share Posted November 17, 2023 Condensers are in front, then a 1-2cm gap, then rads behind. Enough leaves can work their way backwards. Happens if they are never protected. Quote Link to comment Share on other sites More sharing options...
