Antifreeze OEM BMW or OEM Honda

I’m running 110k miles in my M40 X3. There was a coolant issue but other than that it’s been an excellent engine.

I only use honda coolant. My 2003 crv has almost 300k on the original water pump.

I use BMW coolant cause it's similar in price, so why not. Actuall,y a little cheaper cause my dealer does discounts

By “air intake reservoir tank”, I assume you mean it’s the coolant tank for the water-air charge cooler. We need to know what car to tell if the coolant is suitable. That “G30” on the front is the important bit.

Use the OEM honda stuff. It's really nice.

I'm running Honda type 2 coolant in my 94 sonoma. Flushing helped but it seems getting a good P-HOAT coolant stopped or at least paused the rusting while offering better protection.

I used genuine bmw coolant as the price was around the same.

BMW coolant is down right awesome stuff.

They called her back again to say after they started working on it, it's not the water pump, but a coolant leak at the cylinder head, at the head gasket, so what was originally a water pump, is now a head gasket job, 3-4 days.

330i, coolant repairs.
