....I'm wanting one for my kit. I want to try it on the miggy (I don't believe I have a hg problem) but was wondering if the size of the hole in the expansion tank is too wide to get this thing to suck up fumes. the ones ive seen used were on radiators with the cap. the one im looking at is a generic one...
not seen any ''expansion tank specific'' ones

Have that kit in my garage, used it on the wife's Land Rover

thanks joff. was it an expansion tank like the omega or rad?

[joff]

Expansion tank, mine is a Draper one and fits the mig tank

Cheers mate!

You got this one, Joff?

Yep

I recon you could make one easily enough......the indicator fluid is only a Ph detector in solution, you bubble the gas through the fluid and it produces carbonic acid and causes the colour change.

So get a bong and connect the tobacco connection to the header tank, fill the bottle with a solution which contains universal indicator solution and let the gas (if there is any) bubble through....

Don't think that would go down to well if they found out at work i used or even had a Bong

i dont have a bong but i do have a shisher pipe (spell check)

same principle...... isnt it?

Totally unreliable on the omega ime. Dk car sales put one on my old cdx which gave a "might be" borderline result. There are also numerous mentions if these misdiagnosing failed hg on here, and as we know, the omega is often misdiagnosed for failed hg.

I wonder if the fact the coolant system leaks like sieve is prone to the odd leak, affects results. As the CDX had a profuse oil cooler cover plate leak at the time. Hence the test in the first place.

Luckily I found oof results on line that helped me fix the leak. Job done.

I wouldn't trust one on the results alone without other evidence to support it, at best.

On the wife's land rover TD5 the cooling system was/is still being pressurised by exhaust gasses, pushing coolant out past overflow on header tank, get a very good indication with the kit fluid turning yellow. never used it on a Mig, but it will fit.

Completely agree. To be honest i'm wondering whether to even bother. i got a compression test kit already so could just use that. but i just fancied it cos of the ease of use

[Webby the Bear]

Pps, if i did a coolant pressure test and the HG had gone, i'd definitely see bubbles in the expansion tank, right?

[chrisgixer]

I was going up say don't bother, but they may be more accurate on other cars. I dunno.

If it's just for an omega, well, I have no desire to own one put it that way.
