Ok so me and my buddies just threw a b16a2 swap from one eg hatch into another one and now the car temp gauge dont work we changed the thermostat engine head temp sensor , coolant temp sensor and still nothing. the fan does not turn on at all the lower radiator hose is cold upper hot no coolant passage at all it also started blowing whitish smoke once in a while so we dont drive it temp gauge doesnt read anything at all any help will be appreciated we think its the water pump but not sure... thanks
