So my 87 4runner has a small coolant leak. It only drips a tiny bit after it's warmed up. I finally located the place the leak is coming from but don't know what it's called. And I know my engine is dirty. I also had a small oil leak that I fixed and haven't had time to clean it yet. Thanks for your help.


The hose starts from the bottom of the radiator.



Here you can see the drip.


It then ends up right here.

Is this something that is easy to replace? Or would I need to take it somewhere?

 

Your truck is an automatic right? Those would be the hoses that run from your auto tranny to the small section of the radiator that cools the tranny. There is tranny fluid in those lines, not coolant. There is probably a leak a little higher up and it just runs down and onto the lines. Take a closer look.

Dangit. I tried looking further up but can't see anything. What could be above that leaking?

 

And according to the 1st pic I need to replace that hose that connects to the radiator since it's leaking a little bit.

 

Could be a leak anywhere on the rad. Coolant could be running down and that is just where you happen to see it. I would top up the rad and take it for a drive to get it up to temperature. Then use a flashlight or something and look over the rad front and back for wet spots. Most likely you'll see a wet trail from the leak down to that hose you noticed the coolant on.

Thanks for your help. I'll take another look at it in a couple of days when I have some time off.
