I just swapped my E30 320i to M50B20 from M20, the car runs okay, but the needle from the temp gauge jumps a little front and back when driving in the city, and I want to know if I can keep the radiator from M20 with an electric fan, can you give me some advice please?
Unfortunately I have no information and can’t help you in this matter! But if the m50 radiator fits, why not get one! But I would understand if the sensors don’t fit bolt in! But you could check behind the instrument cluster behind the temp gauge and check if the nut is loose(common problem) Or just buy a new temp sensor! Sound like you have an issue in your instrument cluster tbh! Check the nut and look for erosion! After I cleaned mine up and change the si board and temp sensor everything works perfectly
