    86 528e expansion tank hose

    Hi guys I recently just bought a 86 528e that has been sitting for 2 years it starts and idles roughly but theres a huge issue where when it starts it spews out a bunch of coolant from a hose connected to the expansion tank. The hose runs from the expansion tank to behind the back of the front passenger side wheel and from the looks of it there seems nothing connected to that hose. My question is is the hose supposed to stick out from the rear of the wheel or did the previous owner moved it to that location

    That's normal to vent to the outside but it shouldn't be putting out that much fluid

    That is just fine, that is over flow. Do yo uknow the last time the timing belt was changed? If not ,do not run the car until you change the belt. These belts need to be changed every 4 years or 60,000 miles. If it breaks you will cry and wish that your mother had hit you more to get you to listen to reason.
