Heater Hose question (1 Viewer)

Ive been monitoring a coolant leak on one of my heater hoses. Doesnt seem like the leak is getting worse so Im attaching a pic to ask if this is something to worry about? Maybe replace the hose already? Looks new as my mechanic baselined it last February.

I have a camping trip 3 weeks from now so getting the truck dialed in to make sure its good to go. TIA

I would replace the heater valve. Yours isn’t the worst I’ve seen, but that is one way those heater hoses start to leak.

X2 on comment above. If the heater valve is original then that's likely your problem.

Both the heater valve and hose were replaced less than a year ago.

Get in there, get your hands dirty and see exactly why it’s leaking. Maybe just need a tighter clamp ? I just did a rear heater bypass hose and rockauto has the valve for about 25$.

Those do not look like the Toyota clamps I used. But the heater valve is not looking like it is only a year old

The hoses appear generic and cut to fit.

Best guess is the clamp is not squeezing equally or tightly enough around the hose to make a good seal.

However as already mentioned it might also be a crack in the side pipe to the heat control valve so the only thing to do is to disconnect the hose on the right in the photo and carefully inspect the side pipe for cracks and the hose for defects.

If you find nothing, a quick fix might be to purchase a BREEZE Constant torque clamp based on the OD of the replacement hose.

You might also want to invest in a good rubber hose cutter. They're all about the same but IME the blades are often
not super sharp so I take a knife sharpening tool and clean up the blade a bit. Also FWIW a swipe of silicone grease
on the blade before cutting the rubber hose helps the blade go through, IME.
