Hi. Thanks for all the replies Today Saturday just checked the tank level and it has lost an amount on coolant around 150ml. The car has been standing since driving back from Lexus Thursday evening. There has to be a leak be it a small one. There is no sign at all of liquid on my drive. Would a hair line crack or leak on the recently fitted water pump be the cause? Just to state Lexus dealer who fitted the pump could not find any leak Thanks Rob

Thanks Rayaans. Did this early today as coolant reservoir was almost empty. No signs of any leaks or water loss after short drive to reach normal engine temps, smell was evident. Gave in and drove to Lexus who could not find any problem at all they suggested I may have picked something up off the road which had stuck to the exhaust creating the smell, I asked why had the coolant dropped then and they suggested an air block. I must admit I have lost a little confidence in Lexus service which is a shame as I have owned several Lexus cars over the years. Any way back home and coolant level seems to be normal. Strange. I will check tomorrow. Thanks again

Hoping someone can help me with some thoughts or advice... Tonight, 30 miles into a 50 mile journey the cabin filled with a strong chemical/electrical smell which disappeared with the air con on. I got it home, lifted the bonnet and when I rev the engine I can hear a knocking or clicking sound from within the engine. The cam belt was changed recently and also the water pump (approx 4000 miles ago). The engine is still hot but the coolant level still looks very low- is this normal when the engine is still warm? Could there be a leak on the new water pump that was fitted? Any thoughts before I can get into the garage in the morning?
