Rather odd one this morning....took the dog up t'hill in the Rangy for his morning walk and when I stopped there appeared to be vapour/smoke coming from the top righthand corner of the bonnet. Jumped out and lifted the bonnet but the vapour/smoke dissipated within a couple of seconds. No real smell of burning (i.e. plastic/rubber etc) and temp gauge normal for that length of journey - no coolant loss either. Mentioned it to a mechanic friend and he said it could have just been coolant spilled when the heater hoses were refitted and the coolant topped up yesterday, and this may have settled somewhere and then dropped onto the exhaust or heat-shield. The garage did take off the bottom hose from the header and drained the header prior to topping the coolant up - allowing the coolant to spill down the block, onto the floor...not acceptable! Must admit I find this theory hard to believe. Can't find any evidence of burning/burnt wires or components in or around the area (i.e. fusebox, header tank etc), all fuses seem fine and everything (electrical) works as it should. Driven the car three times since, left it running (away from anything even remotely flammable!) and nothing. Strange! Still no odour or visible sign of anything hot or burnt in the engine bay. I was planning to have the car subjected to a full electrical health check in the New Year, and don't really want to bring this forward with Christmas looming....however, neither do I want the truck going up in flames! Any thoughts on this one would be greatly appreciated. Driving it at the minute is probably ok as its absolutely hammering down so would just have to lift the bonnet and let the climate do its job!!!
