Hey guys , recently i did m50 swap , and am facing some troubles plz i need help my engine is going overheated ,i used a E36 radiator new one , thermostat 71 degrees before that i had one with 88 the temperature gauge stay on half to the 3/4 , now with that things i installed , it goes to the half and idle it will go more ... I installed an electric fan with a switch not to a thermostat , so now temp goes from the first mark to the half , but after that i don't feel power coming from the engine whats wrong ???
