My 318is ('93) has sprung a leak, driving along noticed the temp light on.. It is not the radiator or the hoses. It appears to be coming from the engine block to the left (as you face the car) and behind the thermostat housing. Only managed to have a quick look as it was torrential yesterday.
I have read in the manual (Haynes i'm afraid) that there are
| cylinder block drain plugs |
but there are no pictures or descriptions etc. I can feel a square headed plug of some description and close by a small hole which may or may not be missing a bung.
Anyone got any pictures etc..or help with this area of the cooling system.
I can't be more precise as the car is at my mother in laws so can't take any pics right now.
