Saxosim Posted March 23, 2018 Report Share Posted March 23, 2018 Morning All Well ehatbstarted as an exciting time taking my 986 to work for the first time has now ended an absolute nightmare. I literally parked on the parking space switched off the engine and as I got out heard running water, all of the coolant was coming out at an alarming rate next to the drivers rear wheel I am going to try and call a garage to help, anyone experienced this before, any ideas could a hose of come off or something, seems a bit rapid to dump the lot in about 1 minute ? Any help or advise massively appreciated. I assume I will need to get it recovered too on a flat bed. Gutted isn’t even close to how I feel now Link to comment Share on other sites More sharing options...
Boxob Posted March 23, 2018 Report Share Posted March 23, 2018 A failed water pump lets out water at the point. Was there any noise? I think the overflow exits there too. Overheating? Is there coolant in the boot (under the lining)? If so likely to be the header tank split. Link to comment Share on other sites More sharing options...

Sounds exactly like what happened after i parked up when the pump went, under a minute to pretty much dump the lot on the floor. Link to comment Share on other sites More sharing options...
Saxosim Posted March 23, 2018 Author Report Share Posted March 23, 2018 Hiya no noise at all and it was driving nicely. The water pump was also replaced by Mick the last owner a few years ago too. I will go and check the boot liner thanks. Link to comment Share on other sites More sharing options...
Saxosim Posted March 23, 2018 Author Report Share Posted March 23, 2018 The other annoying thing is my newly purchased breakdown cover doesn’t kick in until the 25th either Link to comment Share on other sites More sharing options...
Bike Loon Posted March 23, 2018 Report Share Posted March 23, 2018 Check the number on the coolant cap, the new ones end .04 older ones the spring weakens and they don’t hold pressure so the water goes out the overflow. commin problem Link to comment Share on other sites More sharing options...
Nobbie Posted March 23, 2018 Report Share Posted March 23, 2018 I wouldn't discount the water pump going again, some of the replacement units don't seem to last that well. A simple check to do is to remove the engine access panel behind the seats and check for movement in the water pump pulley. The bearings go and then water spews out.

Patt Posted March 23, 2018 Report Share Posted March 23, 2018 Tends to dump on the OS rear wheel. Molly had 4 pumps in the time I had her - but she did have a tendency to be awkward like that. Link to comment Share on other sites More sharing options...

Doesn't have to be, mine showed no signs before it went apart from a puff of steam from the drivers vent just before i got home. Link to comment Share on other sites More sharing options...
Saxosim Posted March 23, 2018 Author Report Share Posted March 23, 2018 If it is the water pump will moving the car at all damage anything? Also if it is water pump what sort of money would I be looking at to replace it? Thanks for the advice everyone Link to comment Share on other sites More sharing options...
Saxosim Posted March 23, 2018 Author Report Share Posted March 23, 2018 Just checked it is the later 04 cap fitted too Link to comment Share on other sites More sharing options...
Topbox Posted March 23, 2018 Report Share Posted March 23, 2018 Tough luck, but it could have happrned in many a worse place. This time next week it will most likely be all sorted, the sun will be shining and you will be enjoying your car again. OEM pump is around £200, I think for a 986, plus fitting, just had mine done during a service as it was weeping. Link to comment Share on other sites More sharing options...
Patt Posted March 23, 2018 Report Share Posted March 23, 2018 yes you can move it when it's cooled down ie park it in a better spot, but I wouldn't recommend driving it far or for any period of time - things tend to get hot real quick Link to comment Share on other sites More sharing options...

Add a thermostat into that and you might as well put the "upgraded" one in while you're there. Then add the thousands of litres of coolant you'll need and labour (2-3 hours) and that will be the bill. Link to comment Share on other sites More sharing options...
edc Posted March 23, 2018 Report Share Posted March 23, 2018 Check the filler cap area. If it's wet at the overflow then the cap has vented because there is excess pressure in the system. It could also be that the cap isn't screwed on properly. Most likely is that after a drive and then parking up the coolant flow stops but the temp continues to increase a bit. This builds the pressure and it will find the weakest point. If the expansion tank hasn't been replaced then I wouldn't be surprised if that is the problem.

perleman Posted March 23, 2018 Report Share Posted March 23, 2018 Don't the header tanks split too happened on my 997 Bit of a pig of a job to get to on the Boxster Wouldn't worry too much £500 and you'll be back on the road in no time Link to comment Share on other sites More sharing options...
Saxosim Posted March 23, 2018 Author Report Share Posted March 23, 2018 Thanks all it’s at the garage now just waiting till they can get it on the ramp and work out what’s going on.

Saxosim Posted March 23, 2018 Author Report Share Posted March 23, 2018 Hopefully they will look at it today and give me the verdict. If not it will be locked inside their garage safe and sound. I am pleased thinking about it that it went now really and not in 2 weeks when on the border run or not when I was on the motorway at speed. At least there is time now to sort it. I ran it slowly to the garage after putting water in and the temp didn’t go above normal of 80 to 90 degrees which is a bit odd. Link to comment Share on other sites More sharing options...

That means it will still operate but at an angle beating the impeller against the block, hopefully it's not that as there could be a whole load of plastic fan bits floating round your water system now.

I got my Laso pump on a deal from ECP for £150 as didn't want to take a risk with the cheaper ones as I tend to drive my car enthusiastically and reckon the cheaper pumps can't take the high revs. I would have thought 2-3 hours labour should get it done. Good luck? Link to comment Share on other sites More sharing options...
Menoporsche Posted March 23, 2018 Report Share Posted March 23, 2018 Get a pump with plastic impeller, don’t go for metal. Link to comment Share on other sites More sharing options...
Saxosim Posted March 23, 2018 Author Report Share Posted March 23, 2018 Thanks yes I will make sure they fit a good one if that is the diagnoses when they come back to me. I don’t think it’s the expansion tank as there was no water loss since plus the boot floor was dry. There was some water vapour on the boot lid where it must have been under pressure this morning when it dumped its coolant though. The cap is also the newer version with 04 on it Link to comment Share on other sites More sharing options...

Okay thanks the garage we’re talking about ordering one from Porsche if it does need one, what type would this be or are there better ones available? If anyone has a link to some good ones and also an updated thermostat I can send the links to the garage to order. Thanks They usually use europarts for most of their car parts, so they make a decent one quality or better water pump? Link to comment Share on other sites More sharing options...
