HI ..
I have a 2011 Cayman with only 1600 miles on the clock .... Took the car out for Christmas but had a warning on Dash Check Coolant level ...

Filled with top up coolant but then noticed a piddle forming underneath the car .. Quite a big Drip .....

Put car back in Garage then checked later when engine cool ... No leak .. Started car an once again leak ..

Is it the water pump that is the issue ..... ? Haven't looked for a leak yet so suggestion appreciated ...

Many Thanks in advance

Martin


 
Are coolant drips at the front or middle of car. If car really only done 1600 in 4/5 years then it could well be dried out seals in the pump.

Get it repaired and resolve to use it more.

 
I'd agree with John's comments Martin.

A coolant leak at the front of the car is most likely to be one of the radiators or pipe connections whereas if it's at the front of the engine it could be from the water pump. A split in the coolant expansion tank is also a possibility and you could just try replacing the coolant cap (they're known to leak occasionally).

Definitely resolve to use the car much more. It's a driving machine not a garage queen...!

I'd agree with what Jeff & John say but I'd like it to be quantified, how much of a puddle is it? And does it get worse as it warms up? Continuous dripping?

If it is just a small amount and the leak stops after a short time then it could be that an airlock has pushed some water out but also if it has been topped up then as it warms up it may well blow some out as the water expands. You could try warming it up and seeing how the leak goes, I have had water blown off due to overfilling, check where it is, from the RH side of the engine about half way along it the water tank is in the top of the engine bay about that point although it can run onto the engine and then reveal itself fore or aft of that position, as Jeff says the seal on the cap can leak, it won't show at the top up point in the boot. Front of the engine, hoses or as Jeff says pump seal dried out quite possible at such a low usage, front of the car rads or hoses/connectors.

And Porsches are built to be driven not only pump seals suffer from lack of use but oil ways and seals dry out and wear far more rapidly if not given exercise and lubrication.

 
Hi All

Thanks for all the comments and you are all right I should drive it more .......

Seals to me sound the best point to look at .....

Thanks for all your advice
