what diameter of hose do I need?

Post by **trickytroggle28** » 03 Aug 2009, 15:15

URGENT
Can anyone tell me what diameter hose I need. It is the auxillary pipe off the water pump. Is it 9.5, 13 or 16 mm?
I need to know quickly as I have to order it by tonight

Would you like to know inside diameter (ID) or outside diameter (OD), would it not be simpler to remove and measure yours , to be sure you get the right one ?

Regards

thanks for the reply
the inside diameter is the most important but No I cant take it off because it has to go to the garage on Thursday and if it snaps or is damaged then I am up the creak
thanks

does anyone out there have a manual that they can look in, surely it will tell me in there what hose is required. Does anyone have a manual available to sell or donate?

kev, I think it is no 38 but itshard to see, I was told by the garage that it is the auxillary pipe off the water pump, it has an elbow in it and is about 4" one side to the bend and 3" the other side, does any of that make any sense. I have a photo

ok kev as I said I think it is 38 but your diagram looks different to all the hoses etc that I see in my engine. I can get the hose I want I just need to know which size internal it is. I have a photo-how do I send that to you?

OK I'll measure mine and tell you...

sorry that sounds disgusting

ooooooooooh it worked but is very small, can you see the one I mean, it is the largest hose in the picture me thinks

Post by **kevtherev** » 03 Aug 2009, 16:47

Ah ha!
yes it appears the oil cooler has been bypassed!
that's why it looks different

any way it is 15mm inside diameter.

fab, so should I order the 16mm internal pipe? Do you know where I can get a silicone hose from? I have found a company called Merlin motorsport who have 9.5, 13 and 16mm
Thanks Kev
