Coolant reservoir hose leak?

Hi guys, my 2012 SR5 is leaking a few drops of coolant from the hose where it meets the bottle, Sounds like this is a pretty common issue, just snugg a clamp down over it and be done?

 

Sounds like a reasonable solution.

 

Had the same issue with my truck last year. I disconnected the hose from the tank, cleaned the dried anti-freeze off, lightly scuffed the mating surface of the tank nipple with a Scotch-Brite pad, then put the hose back on with a new clamp. Problem solved.

 

A zip tie pulled tight also works well.

 

I used one of those spring clamps that comes with fuel filters on mine. If you use a screw clamp, be careful not to over tighten.

 

Thanks guys, I’ll get on it!

 

I clamped the hose today, haven't driven it yet to see if it is leaking, but I started thinking, why is the radiator kicking coolant into the overflow to begin with? Is that normal with this radiator system? The other thing I was wondering is if the vent hole under the cap on the overflow is where the droplets are coming form, any thoughts?

 

When the coolant gets hot it expands and the extra fluid goes to the overflow tank. When it cools off and contracts it takes fluid from the overflow tank.

 

Right, so this is normal, I was under the impression the coolant overflow was only used if there was some other issue with the radiator not being able to contain the coolant, Excuse my ignorance haha.

 

Yes completely normal.

 

In the old days radiators were not completely filled with antifreeze. There was an inch or two of air space for the coolant to expand when hot. The air did not just stay at the top of the radiator, it circulated throughout the cooing system and reduced the effectiveness of the system. It also increased corrosion as the oxygen in the air reacted with the coolant and the metals in the system.

 

Mine did the same thing. I replaced the hose with a new silicon hose and put a band clamp on it. As has been stated, do not over tighten.
