Heater hose

[KennyW]

H All,

I've got a pesky leak from a heater hose No 11 Citroen service (part No 6466 27), this part s NFP

See attached picture.



Simple question what size is it?

[Peter.N.]

Probably about 5/8" - 3/4" I would think. Can't you measure it?

Thanks Peter,

I am going to do that but I was hoping someone may have had to replace/find replacement and had the size.I want to be prepared before remove and refitting since I have to empty the coolant. So going to replace coolant with new stuff.

Measure the outside diameter, I would think the wall thickness would be about 5mm, can you see the end to measure it? Most small hoses are about the same size, used to be 1/2" but I think its nearer to 3/4" now.

Hi Kenny,

The internal diameter is 3/4" from what I remember.
Working on the heater hoses is very tricky because the plastic connector to the matrix is brittle.

Sticking a piece of gaffer tape will keep the coolant in for now, and driving with the coolant cap loose will prevent pressurisation.
I never tighten coolant caps, and no problems here even when it’s 30 degrees.

Happy New Year.

one of my xants 1.9td broke its aux belt and damages the bottom hose...i was stuck and needed to get to work so i went to halfords and bought an exhaust repair kit and wrapped the hose up...it lasted till i broke the car..but to the point as a precausion i took off the coolant cap and continuied to drive...infact i diddnt put it bk on and i done thousands of miles like that..just astonished it diddnt spew all the water out or evaporated(well i did top itup every now and then but it wasnt more than a mug of tea!

Thanks for the replies Clogzz and Taffy,

At the moment with the amount of rain falling there is no need to top up 3/4 " ideal was think of using a new plastic connector.
