2000 BMW 740iL Q&A
2000 BMW 740iL Question: im losing coolant,have to fill atleast twice a week.
Does vehicle consume engine oil? Smoke could be Engine oil consumption or coolant is finding its way into the combustion camber internal leak. Step one psi test cooling system when cooling system is cold only. Best practice with Spark Plugs removed. Repair any external leak first. If no leak is present possible cylinder Head/Head gasket could be the case. Good luck - M and R Car Import
