I was going out with a few friends the other day for a bit of a spin. We drove about 30 miles up around the 100 mark, when we stopped a small amount of steam was coming from under the bonnet. After popping the bonnet i noticed it was coming from the back of the engine, (toward the drivers side) next to the bulk head, dripping down onto the exhaust.

 

I couldnt see much in there (pipes and engine everywhere), so i let it cool down, checked the water level and it was still full!!

 

I then went on to drive another 150 miles without a problem at all - still holding water, and no steam !!!!!!

 

I seem to remember this happening on a particullaly hot day last year - drove down the road and got steam from the same place - after driving further i had no leak !! On that occasion, i had the Econ on, and i put it down to the condensor for the Econ - however the last time it happened, i did have the blower on but not the ECON - any ideas ???

That'll be either of the heater pipes to and from the matrix. Not too hard a job to change, best doing both at the same time, £15 each from Nissan.

 

Maybe the jubilee clip needs tightening tho, or you could have a pinhole leak which drips under higher pressure when its hotter. They are right above the exhaust so you'd hear them drip.

 

Good time to swap them anyway before they go pop and you go home on a flatbed ;)

 

Cheers
