I need some help desperately. My 2007 toyota kluger when I got it , it never had any problem with the coolant system. Only recently in the last 2 or so months the coolant levels seems to go very dangerously low, but there is no signs of a leak anywhere. I had a mechanic look at it and he can't find anything wrong with it. I am spending alot of money on coolant and I have to constantly refil it everyday. It will be at the correct level when I park it at home and the next morning it's so low it's dangerous but again no signs of a leak on the ground or anywhere. I need help I can't keep on spending money on the coolant.
The cost of coolant is the least of your problems. If it's not leaking, it's burning. Have you checked your oil lately to see if it looks like a chocolate milkshake?
I have and the oil looks just fine, looks like when I had it serviced a few months ago.
Replace the pressure cap
Any weird smells in the cabin?
