Never seen either - but there seems to be about £30 difference in price - do they both do the same job?

Sorry - I can't find VS00041

The info. on Sealey's website says 12 c.f.m. so 12 c.f.m. it is....as I said, you may get partial movement at less volume, but it won't work properly. If it would work on less, then the manufacturer would say so. What air delivery do you have?

Hi Helen,
I have no air delivery system (excluding personal orifices) -- but thought about buying a Sealey cooling system filler and compressor to make flushing and working on the bongo cooling system easier. But compressors that can deliver 12cfm cost too much for me. I had an e-mail exchange with an engineer at the company that produces the Mityvac, which is an American equivalent to the Sealey VS0041. He said that having an underpowered compressor would not be a problem -- only it would take longer to achieve sufficient vacuum on the cooling system. I don't have enough of a conceptual grasp of the issues involved (design of tool, physics) to assess whether the engineer is correct.

Ive got ALDI compressor and it states 9.5 cfm.

Yes the Bongo is perfect after the use of the VS0041. I have now used it for a couple of long runs yesterday and today. Both with my dinghy towed on the back and no sign of any airlocks. Temp on the gauge fitted with the Haydn alarm and the head temp from the Engine monitor were perfect.

To those that ask about the specs of the needed compressor. My paperwork with the VS0041 recommends a 10cfm output but I am using a Wolf Souix II with a rated output of 9.5 cfm.
Once I had sorted the airleaks from the cooling system that were preventing a complete vacuum then the compressor went to the required amount of vacuum on the gauge (and slighly beyond) no problem at all. I reckon that you could get away with less than 9.5cfm but the compressor would be working a little harder.

I know that this may ceate some debate and conflicting responses but all I can say is that itis a great little piece of kit that made replacing the coolant almost a pleasure rather than a pain. Just to add, before I bought the tool I spent some time asking questions and searching for one that did the job. I wasn't looking to waste my money and and pleased to say I haven't.

If anyone in the area wants to try the item I'll gladly let you as long as it fits in with my time.

Ah - smac had an extra nought in there - it seems to be the VS0041

That's great steve, glad to hear it. Have you a constant heat from both heaters when turned up to hot?

Hi Steve
That's a good bit of news...10 c.f.m......my compressor will manage that, as I use quite a few things rated at that. I wonder why Sealey's website states 12 c.f.m....??? Would there be any chance of PMing me with an excerpt of the instructions?.....I'll probably end up investing in one and do an annual coolant change as Doone suggests.....makes it well worth buying, and Tony won't get scalded
Cheers
Helen

Bigdaddy cain,
Yep, both heaters blasting it out

Helen & Tony,
Will send a copy of the instructions after the weekend when back from a trip. Or go to http://downloads.toolsnstuff.co.uk/seal ... VS0041.PDF and download the instructions from there. (Clearly says 10cfm in the instructions so don't know why various suppliers are rating it at 12cfm)

Hi Steve
Thanks for that link....yes, it states 10 cfm. Lets hope everything is O.K..I must say that I would have chanced buying one before if it wasn't for the quoted figure.
My reason for being a bit pedantic over air supply is to let folk know that not every compressor will run all tools. Compressors are sold quoting the output in c.f.m. DISPLACEMENT....this is the theoretical air delivery based on the cubic capacity. (the same as a car engine's capacity)....and the theoretical value is worked out per minute in terms of delivery....The ACTUAL delivery is known as "free air", and is the real delivery rate....substantially less, and this is the figure (not always quoted) to look for. Many tools are sold requiring a given delivery rate, and , in my experience, they often need more than quoted, unless you go for very expensive equipment.....Sealey stuff is reasonable middle-of-the-road....i've quite a few of their offerings. If you want a compressor , then think of your future needs, and add some.
A small 25- 50 litre tank compressor giving 7 cfm free air is grand for painting, waxoiling, etc. if you choose suitably rated guns....also stapling/nailing/greaseguns. If you want to use paint guns of the HVLP type, and air grinders/saws etc. you need 150 litre (min) tank and over 16cfm delivery
A good compressor will last for a lifetime of DIY....You can whip the house doors off and spray them....treat the fences....the list is endless. I'm no expert, but I've been tinkering for over 40 years ....mainly for "artwork"
Cheers

Thanks steve, job well done mate!

Looks like a piece of kit to invest in I need to do a coolant change and a quick method would be great

Just borrowed a manual pump that will do the same job- without a compressor Will be giving it a go tomorrow Will update how I got on

Well I have bled the system today What a wet day it has been The piece of kit I borrowed is in fact a pressure tester for the radiator--A Zeca ART.415 My coolant change was 2 months overdue, I drained the system and the coolant drained was just slightly muddy coloured. I then flushed the system with a hose pipe, this removed quite a bit of crud, more than I expected This just highlights the need to keep on top of the replacement and flush of the coolant system I then filled the system with the coolant 50/50% I placed the adapter onto the expansion tank and pumped it with the bleed hose raised, I pumped till the coolant started to come out of the bleed hose. I then bunged up the bleed hose and pumped again to 1 bar I checked that the system maintained pressure for several minutes-indicating that there were no leaks I then slowly opened the bleed plug and released a small amount of air. I started up the engine and ran for about 10 mins see-sawing the bleed pipe up and down, very little trapped air escaped, I ran the heaters on full, they did not heat up. I stopped the engine and topped up the system. I then ran for a few minutes on tickover with the bleed pipe sealed. The heavens opened so I retreated indoors for a quick sandwich I then went for a trip out, as I set off up the road the heaters came on full heat I then headed up several steep inclines and along the by-pass at a steady 80 m.p.h, all seems well left the old girl to cool down then topped up the coolant to correct level- will check level again in the morning

bit of a misprint Mr Plod, he meant 70m.p.h.
