Small Coolant Leak.

[Cormo]

Hi,

Is there anything special about the heater pipe to thermostat housing o-ring due to its  exposure to temperature & coolant?  If nothing special, what size?  Where do people generally buy them, from Ford or aftermarket etc?

What type & ID sized hose is required to replace the two short pieces (2" approx.) in the water coolant lines that run to & from he turbo.

I just want to make sure I've got the right bits beforehand so I don't get stuck over the weekend.

 

Thanks . . .

If this is the right bit then I've taken some pics with some measurements and also included a conversion chart from metric to imperial. The bottom picture shows a hard, old farked one compared to the good condition green one.

 

As for the type of hose I just salvage old hose I have lying around for small bits like that but here is some hose info if you are interested.

 

 

 

 

 

 

 

 

 

Tl;dr

2 bits of 3/8 hose @  6 cm and 7 cm

The large o-ring has a 19mm ID

 

Nice mine there too by the way

Spot on, thanks for all your effort & measurements.  Exactly what I was after.  Appears as though the hose has to be coolant hose not fuel hose.

No worries. Fuel hose will work but if you're buying it then get coolant hose.
