Coolant System

Recommended Posts

The water pump on my 02 C2 is due for another replacement. I do this at 60,000 mile intervals as a preventative measure. While doing the pump I’m thinking that this would be a good time to replace the coolant tank.  Its still original unit and though is not leaking it looks very yellow and brittle. 
I’ve read what others have posted on the tank replacement and their clear instructions are much appreciated. My question is; are there hoses or fittings related to the work that I should be replacing or at least, have on hand ?
Thanks for all the help this forum has given me.

There is a hose that comes out from under the coolant tank that has a plastic T fitting.  You will break that T fitting.  And also the plastic coolant fitting next to the alternator will surely break as well.  There is a SS metal coolant fitting that is a much better alternative.

 A couple of thoughts having done this a few times because of mistakes I made;


1. The part you'll likely break is the coolant level sensor on bottom of tank, but it's cheap


2. Pay up for a Genuine Porsche tank and cap


3. Drop the engine a few inches- it's easy and will give you room


4. on mine, the fuel filter is attached to tank- change it while your there. Get 2 stubby 19mm wrenches and it's easy.


5. I swapped a few of the spring clamps to screw type by necessity. Didn't change hoses. They looked fine on my 20 year old C4 with 130,000 miles
