Pls how do I solve the problem of smoking from the radiator area when I start the ignition and the engine steams. The car is a 2003 Toyota Rav4. I did some repairs recently including electrical but the battery has been weak despite several recharges. The fans are working. What could be the problem and solution? I need suggestions please..

for ba3 seems a wrong electrical connection is causing ba3 drain. a good electrician should look into it. If the fan start immediately you switch the ignition on, then the car has been remixed, you need to unremix the car

for smoke coming from radiator, i dont understand the explanation. but if you open bonnet, start the car and when engine is warm smoke is visible, then there is a leak of fluid, could be engine oil, could be steering oil, it could also be ATF the leak is dropping on the exhaust manifold/hot metal areas. but you need to investigate it yourself to ascertain leak location
