Tacoma coolant overflow tank purges coolant ?

I’ve noticed coolant on the outside of the overflow tank when I get home and wondering if it’s a Normal characteristic. It’s never low though

 

Check the hose on the tank.
It’s been know to leak.

For good measure, check the level in the radiator too. Just to be sure.

 

Check your radiator cap as well, it may be going bad and not holding pressure.

 

Might try a new pressure cap just for good measure.

Mine spits a little coolant out of the reservoir too, but it never really needs topping off.

If it never overheats and never needs topping off I wouldn't worry too much about it

 

Someone recently posted a similar issue. The op never said so but I’m certain he just needed a new cap. You can read through the suggestions there.

Thanks guys!

 

If the cap is good and no issues with head gasket it will self adjust from an overfill. If you fill it to the hot line when cold, excess coolant will come out of the overflow when hot. Check the coolant level in the radiator when cold. It should be right at the rim. A good cap will allow it to suck in coolant as it cools and capture it when expanding as the temp rises.

 

Yes sir checked it at the end of the work day cold and it was right at the brim. Ordered a new cap from Amazon for $16 Oem part for shits and giggles. Thanks!!

 

Good deal.

I too would have went with OEM cap. Not the biggest fan of Stant. Or other after market cooling suppliers.

 

oem is always the best bet IMO. cheers!
