....is this going to work, really?
It's a foot pump with the end clamped to an old bike tyre valve and then jubilee clipped in place inserted in the coolant hose (to plenum)?
i think it was nick and cvhris that suggested this... and in no way doubting you but will the pressure bot simply escape past the jubilee clip? :-\
if youre confused as to my description (i confuse myself easily enough) ill get a pic up tonight! :)
-
Now I'm confused, as I would buy a cheap mountain-bike inner tube and cut it opposite the valve. Fit that instead of the most convenient radiator hose, and retain it with Jubilee clips. Add about 20psi pressure, and leave for a while. If the pressure holds, the system is good. This works for radiators that aren't in the car. You inflate bike tyres to 100psi, so the pressure isn't a problem for the valve!

Yeah thats what ive done :)
This has then been attached to my foot pump by the foot pumps clamp.
then shove that in the coolant line and small jubilee clip... job done.
thanks for confirming that nick :)
should the pressure hold for a long time?

Why not use a tyre valve in a spare pressure cap? ::) http://www.omegaowners.com/forum/index.php?topic=90598.0
-
I mean to attach the entire tube, not just the valve. I've pressure tested loose radiators like this, not just systems.

You know that is a really good idea....and so simple. :y
I do like a bit of ingenuity.
-
I use the tyre valve in an old coolant cap method. Oh, and plenty of sealant ;D
-
I was gonna make that as I do have a spare cap but just too much hassle.
This is my alternative...

Obviously I'll need to trim the edges to fit in the coolant hose but then I simply put a jubilee clip round it and then done.
Good?

Unless we are in a car park in Wycombe and Mr Admin has left his modified coolant cap at home. In which case he (we) uses a foot pump and an air bed type adaptor on the throttle body coolant pipes found in Josh's boot. ;)

I think young bear is a bit fuddled. Perhaps.
The original description involves using the the red or blue, forget which, adaptors that come with a foot pump normally.
Attach blue(?) adaptor to foot pump.
Remove throttle body coolant pipe, which you will have done to remove plenum.
Fit blue adaptor into coolant hose.
Clamp the other coolant hose to retain pressure.
Pump up coolant system.
Seemples.
That's not to say that's the only way to do it. Depends what you have available. Most people don't have a spare coolant bottle cap. But if you do. Happy days. Fit tyre valve and away you go.
You can even seal your mouth around the bottle neck and blow, as a last resort. Only needs a few psi. Or even just positive pressure. Although the leak might take linger to show at lower psi. And you might turn blue before anything happens ;D
Any more than 1(?) bar and an un modified cap will leak by anyway.

Wouldnt have it any other way ;)
Thanks chris i get that explanation. :)
hope mine (in pics) will work tho/ would add another way of doing it to the list :)

Guys sorry to bang on but just one last question...
If it ends up that I have to blow in to the expansion tank should I drain out coolant first? And can I simply blow in to the tube that's attached to the plenum?
-

No, and yes. Well, the throttle body coolant pipe is part of the cooling system so yes.
If you drain the coolant out there won't be any to leak out under pressure.

God, I am sooo dumb at times :-[ :-[ :-[ :-[ :-[ :-[
Thanks Chris!!! :y

Draining the coolant makes it a rather pointless exercise ::)
For practical 'blowing' purposes, obtain another hose from the rad to expansion tank, cut in half and fit a T piece :y
When time comes to test a car:
1. Open expansion tank to release any pressure.
2. Fit your modified pipe.
3. Refit expansion cap.
4. Put your lips together and blow... into the T piece.
Seeemples :y
