BEC coolant hoses - show me your setup
Hello to everybody and my best wishes for a Happy New Year to all!
I would like to have a look at your coolant hose setup of your BEC.
I am preparing my engine to operate and i would like to have a general picture for how should i connect my engine to the radiator.
Did you use silicone or cheaper rubber hoses? What did you use to connect different hoses (alloy connectors?) that could not be one piece? Any
T-pieces required, elbows, bends etc?
In case your engine has an oil heat exchanger how did you connect the small hose of the exchanger to the larger main coolant hose?
How did you connect the small diameter hoses of the expansion tank to the main large hose?
And who is your hose supplier?
Thanks in advance!

First welcome to the mad house.
What engine are you using?
I used silicone hoses but there's no good reason not to use standard rubber. Silocone were just easier to locate inthe required shapes and
sizes. I made up link pipes in copper with soldered bends and connectors. Easy to.do
not as pretty as purpose mader andy welded ally.
Ps. Add your rough location to your profile. Someone local might be able to let you see thier car.

Hello!
My pics and description of tasks are from putting pipes on a CBR900 (Fireblade) carb'ed engine.
I used rubber hoses. They were provided by Aries Motorsport, from whom I bought the kit.
All the pipes and 1st steps connecting them: http://happyblade.blogspot.com/2011/06/beginning-pipework.html
Header tank fitted: http://happyblade.blogspot.com/2011/07/rear-brake-calipers-and-more-pipes.html
Type of braces used: http://happyblade.blogspot.com/2011/07/water-pipes-and-bulkhead.html
Connecting pipes to radiator: http://happyblade.blogspot.com/2011/09/refrigeration-circuit-done-and-other.html
Note on the last link that I have a housing for a water temp sender. This sender is wired into the loom and will provide info for the dash (and
control the radiator fan). I believe this is optional, but its lack will force you to have a dash mounted switch to control manually the radiator fan
when you "sense" the water's temp may be getting high. With all the risks associated with manually controlling things...
Have fun! It's a wonderful journey...

Here's how i plumbed up my ZX10R
Silicon hoses, hose joiners, reducers bought from ebay
During fitting
All finished, slightly different setup here as i have a second water pump feeding a second boot mounted radiator, but you get the idea

Thanks for the help guys!
@SausageArm
Are these silicon hoses flexible enough to bend without crimping?
I ask because in the second pic i only see some straight lengths of hoses, while on the car setup there are some really tight bends.

I found it depends on the diameter of the hose and also how many layers (ply) it's made up of.
Eg. the 2ply hoses bend a lot better than the 4 ply or the 10mm diameter bends better than the 40mm.

Thanks!
Could you tell me how you connected small diameter hoses to large diameter ones? For example the connection of the header tank's bottom hose to
the main coolant hose. Did you use an alloy t-piece? Do you have any pics of this connection?

I have made a quick sketch of my setup. Do you think it's the right thing?
As for the header tank, i cannot see why it should have 2 inlet hoses, i have included only one inlet connected to radiator top overflow hose, one
outlet at the bottom connected to the main hose (water pump side) and one overflow outlet ont he cap.
What do you think of the designed setup?

I used a self sealing hose take off, which comes in a kit like this
i've not got a photo of my actual hose but this is one i found online showing how it looks once it has been fitted

I think your design looks ok, but do you not have a small hose coming from your thermostat housing?
I've labelled up my engine bay in the photo below, so you know what each hose is connected to.

Thanks for that!
No, there is no extra hose on the thermostat housing on my engine.

Hi again mates,
Could you please tell me how exactly do you bleed your cooling system?
I am using the VW302 radiaror (popular in BECs) and there is no bleeding points on it.
Can i bleed the system by having the header tank cap off, running the engine up to temp and then waiting for all air be removed from the header?

Hi
this is the layout we used & works perfectly on R1 engine
I don't know if it would be suitable for yours ?
We used mostly silicone hoses.
(see sketch on our photo archive)
Good luck.
