Hello. I have a question for you about my 06 vz wagon. I look after it it's serviced. I checked the coolant and everything but today randomly my temp gauge spiked. All the way. Checked coolant and I took about a litre. I check my coolant all the time and in the 8 months I've had the car it's always been fine. Since this happen it seems to be burning through coolant somewhere. No leaks. Nothing from hoses yet I've put away 2 litres of coolant in it. Its all clear and no milk or muck. Also found this hanging down. Doesn't explain the heating but what is it.... Any ideas? Really hope it's not the head as that makes no sense. Coolant level is always fine. I don't thrash it and it was serviced in November... Thanks for the help.
