Stupidly Overfilled Coolant Tank.


Recommended Posts

Hi again all.

Today I took my 996 out for a spin. Before I did I checked the coolant level and noticed it was just above the MIN mark.

So I decided to top the coolant up with 1.A full bottle of Redline WaterWetter and 2.Some distilled bottled drinking water. No sooner did I pour in the bottled

water about 500ml or less and the tank was overfilled!!!

The level is just above the word MAX (yes I know before anyone say's it, it's marked MAX for a reason :) )

This maybe was stupid of me, but I thought I was at least capable of toping up my coolant?

So the questions that are worrying me, are:

1.Is there a coolant overflow pipe

2.Will the excess coolant drain itself via this overflow pipe

3.Will I now have to purge the tank to eliminate any air bubbles in the system

4.Will this cause any serious problem for the car, can I drive it?

Many thanks guys, in advance.

James

Quick fixes when the engine has cooled down:

  1. Open the coolant reservoir cap and remove some of the coolant with a clean syringe or baster like ones used for battery top up or cooking meat.
  2. Use a clean lint free cloth to soak up the coolant and squeeze out the cloth and repeat until the level is OK.
  3. Check the relief valve to the left and forward of the coolant filler cap (looks like a black filler cap with a spring clip and plunger arrangement on the top). If the system is under pressure the plunger may be raised (check by pressing down, it will feel springy). Move the metal clip from the horizontal to vertical position above the plunger so the bottom of the clip is resting on top of the cap and the plunger is raised. This physically holds the relief valve open. After driving for a couple of hours and keeping an eye on the temperature gauge the level will probably have dropped and the system will have had a chance to purge any trapped air. Don't forget to reset the relief valve clip to the normal horizontal operating position when you are done.
