low coolant resivor - nissan x-trail

By the way.... I forgot to add that I STRONGLY advocate the fitting of a low water alarm to every vehicle .... Engine Saver Low Water Alarm

I have no interest in this business, just a very satisfied customer. Remember that if you suffer a split hose or radiator which causes the loss of your coolant, you WILL NOT see it register as a high needle on your temp gauge.... in all liklihood the motor will be cooked before you know anything about it. The Engine Saver will alert you about low water AS SOON as you've lost about 1 litre.

Hi Roachie,
I second that, money well spent, They also sell now a Low Coolant Alarm that has a Temp gauge that gets it's sensor bolted to the is engine block.

Low Coolant Alarms And Block Temperature Sensors

So now Roachie, not only is there the warning of low coolant, if for any other reason the temp may rise, broken fan belt, seized water pump or clogged radiator there is an accurate temp gauge.

I don't have any affiliation with this company, I just believe they have a great product and highly recommend it.

thanks for the replys,
if there was any signs of a cracked head or heads, would the car be running ruff or just normal?
would it be an idea to put a little bit of water in the resivor, mark it on the side and see if it goes down?

thanks for everyones help!

Most likely your coolant level has dropped because there was still air in the system after the dealer changed the coolant, and that air has since been eliminated. That's why I suggest that you watch it.

But if it continues to fall substantially, then you may have a problem. If it doesn't change, then you're fine. The level in Xtrails normally drop a couple of centimetres every 20,000k.

Engine often runs normally with a small head leak. You just start losing coolant or the main radiator level drops or you see bubbles coming through in the coolant when the motor's running. The Xtrail forum has a few threads from people who have had this happen - not common, but can happen.
