We offer a guarantee that Prestone is suitable for all cars and engine materials. It can be used in all cars effectively, offering the same levels of protection, and without any damage. Prestone is an OAT coolant/antifreeze but also contains anti-corrosion ingredients to protect your cooling system. Designed for both diesel and gasoline engines, the coolant has low-silicate, pH, anti-phosphate technology that protects all metals, like aluminum against corrosion. The ZEREX G-48 coolant is ideal for BMW cars. Replace Cap – Secure the coolant reservoir cap.Add Coolant – Determine coolant type and add fluid properly.Check Level – Determine the coolant level.Find Reservoir – Locate the coolant reservoir and clean it.8114117) Does BMW require special coolant?Ĭoolant & Antifreeze BMWs have specific coolant requirements (nitrite and phosphate free) to prevent build-up and corrosion of aluminum components, so not just any off-the-shelf antifreeze will do. Pentosin – Pentofrost NF (G11) Silicate European Concentrate Antifreeze / Coolant – 1.5 Liters (Part No. Given that the coolant is blue, it could be that the cooling system has been adversely affected by the use of a coolant type it wasn't designed for, though I'm not sure if I would blame it for this vehicle's coolant loss woes.24 How do you top up BMW coolant? What kind of coolant does BMW X3 take? I'd recommend cleaning the oil spots and monitoring to see if the stains return in the short term. The power steering reservoir is also a possible culprit.
BMW COOLANT LOW CRACK
If the oil hasn't been changed recently, there may be a leak associated with the neighboring oil cooler or a crack in the oil filter housing. Given the oil filter housing is in the nearby vicinity I wouldn't be surprised if the stains are the remnants of a recent oil filter change. The reason for this should be obvious, but the consequences of engine damage from overheating is far worse than any impact of using the wrong fluid on the cooling system.Ĭoolant evaporates and leaves a milky-white stain behind that's oil on the radiator hose If the recommended coolant/coolant grade is not available and the coolant level is low, top up the reservoir with distilled water and have the system evaluated by an authorized dealership as soon as possible.
BMW COOLANT LOW MANUALS
In a pinch, any coolant is better than no coolantĮven litigation-wary vehicle manufacturers will invariably recommend this in owner manuals (paraphrased from my W12 Touareg manual): I am attaching following picture that may provide more hints, because there is fluid exhausted with force from what I think is radiator hose: The coolant is pouring on the street (in this case there could be something dipping below the car)Ĭoolant gets burned together with fuel and goes out through exhaust pipe (not sure what hints are for this case).Īre the any possible root causes that could explain why coolant disappears? I guess there are three possibilities:Ĭoolant is leaking in oil compartment (in this case the oil may become milky) I suppose it is also important to find out why coolant has disappeared. If it is better not to drive around in current condition, can I simply pour in a liter of distilled water to get the car around for a day or so? I guess this would dillute the water:coolant ratio from 50:50 to something like 60:40. If coolant reservoir is not completely empty and low coolant light is turning on only intermittently, is it ok to drive around for a day or so for short trips until this gets properly fixed? Does this kind of job imply also coolant change? if so, then I guess there is possibility that it is not the blue BMW coolant in her car anymore and in this case the coolant should be flushed if its type can't be determined anymore? She got engine gasket replaced outside BMW a year ago. I would be inclined to buy and pour in new coolant, however, after googling around I have few doubts now: Nevertheless, the float stick was still floating and there was still some fluid left inside the reservoir. I checked the coolant reservoir and float stick was slightly below the "low line". In the last few days the "low coolant" light has been intermittently turning on on my friend's BMW X3 (2007 ~70K miles).
