alright , i recently bought a Nissens radiator fom my 95 525i. it seems that this radiator has an internal oil cooler integrated. the external oil cooler on my 95 seems to be punctured and leaking oil. my question is can i utilize the internal oil cooler on my new nissens radiator and use the lines that are on the 89 525 i because the earlier years actually do have internal oil coolers intergrated into the radiator. i want to steer away from purchasing an external oil cooler from bmw. is it possible?

anybody?
