The engine bay gives off the subtle scent of burning coolant. I check underneith the vehicle to find a wet spot under driver front. Not much of a leak and I don’t actually see an active drip. The source is under the drivers side radiator. I can’t see the true source but this is as far up as the wetness travels. The coolant level in the reservoir doesn’t seem to change. I’m hoping this means the leak is sloooowwww. Any obvious tips as to where I start. (Aside from straight up radiator replacement). Is there a common source in this area?

 

 

Check the two hose connections on the top, driver side of the rad. There's the main hose from the intake manifold and a smaller line that feeds back to the reservoir.

 

It also could be the water pump gasket. Mine started leaking like that last August and it was the WP gasket.

 

 

IF the leak is from the Radiator on the Drivers Side (providing it's not the tank or core) remove the Fan Shroud and have a look at the above 3 areas.

 

And easy to check for leaks there.

Otherwise you need to use a good flashlight and inspection mirror to visually inspect for leaks from above and while beneath on your back looking up. Helps to remove the underbelly panel.

Your leak is not slow enough to ignore and just keep adding coolant.
