Thanks guys & Stuart G- much appreciated (as usual). I had a new coolant tank put in at the unbelievable cost of $700.00 AUD- I questioned this as I researched the net and could have gotten the part for $200.00AUD and I imagine labour would be relatively uncomplicated being at the top of the engine and easy to access...so they dropped the price to $500.oo, still outrageous for a piece of plastic, even if it is under pressure....so in answer to all that- expansion tank works like a dream.

 

I am glad you haggled the price. The expansion tanks pay I think 1.2 hours customer pay. I don't know why your extended warranty would not cover the expansion tank.

At any rate, glad your heater is working fine.

 

Thanks for that tip, it's HUGE as the #1 cause. Will check mine right now!
That's why I was checking this thread. Keep up the xlnt advice.
