Wth is this random hose?

welcome!
did you put those clamps on, or were they already there?
how many miles on your car?
are you the original owner?

 

I can only see a short portion of it on my car and can't see either end. But if I had to guess, I'd say it must go between the radiator and the inverter coolant pump. The end you're holding is hidden by the hood latch on mine.

 

Took a look at ours: that black plastic junction is a Y shape, with two spigots on the right side. The disconnected hose looks to be the lower hose on right side.



I've heard the screw-style clamps are tough on the spigots btw, create a "point load". The kosher clamps provide even pressure. Also, there's no clamp on the left side, as it comes from the factory. Ours has been fine thus.

 

i googled 'kosher clamps', they don't seem to be available in the states.

Must have more Rabbi’s up there?

 

They are called "Corbin" clamps, although the original "Corbins" were made of wire. Dorman makes them. I've seen small ones available at Pep Boys. Larger ones for radiator hoses are available on Amazon.

This type of clamp is preferred and used by most OEM applications, because it applies even pressure on hoses over plastic fittings. Common worm drive clamps impart a "stress riser" at the point under the screw area which could eventually destroy the fitting underneath. The worm drive screw clamp should not be used to replace OEM Corbin type constant pressure spring clamps. The spring clamps should be replaced with the same type for long plastic fitting life. Should the hose in the clamping area compress with age, spring pressure will maintain pressure and the seal.

When I installed my OCC, I used Corbin type clamps. that I got form Pep Boys.

 

@Georgina Rudkus thanks for the info. I ordered this:





OD of the 3/8" fuel lines I'm using is 5/8" (aka 16mm). Only thing: it is a royal pain to pry the hose off hose barb fittings; might be simpler to just buy some more hose. My lines were both slightly short anyway.

 

for the briss?

 

Oy

 

Was that Y-connector missing when you got the vehicle? Something fishy here.

 

maybe you need new hoses

 

could a blown head gasket or clogged egr cause excess pressure?

 

sorry to hear it. this is a big problem with gen 3, and 2010's especially, since they have the most miles.
i hope the mech is wrong!

 

Bisco all up in there
