Post by **ermie571** » 02 Jun 2008, 21:17

ok folks...here's one for the technical gurus!

what is the internal diameter of the steel front to back water pipes on an early (1984) 1.9 dg waterboxer?

(need to know as I have been advised by elite that the quaickest way of replacing front to back pipes is to run a rbber hose own inside them!)

Hi Em
the external for a 84 model is 32 mm so the internal is prob around 28mm , although i would be concerned that you would end up with a much smaller internal bore if you push rubber through them, and this may? lead to overheating! later models used plastic pipes with an external of 37mm.
sorry if this hasn't helped.

Martin - that is brill! many many thanks.

I was concerned about the overheating issue too...but the chaps at elite seemed to feel that the thermostat would open a little longer....

I have got the plastic pipes in the garage.....2 sets.......but means droping the tank and this is what we are trying to avoid.

Anyone used smaller bore pipes?

i'm sure someone said you can get the new pipes in without dropping the tank?

I have fitted both pipes with the tank in situ. went from back to front, there is a metal clip joining the two pipes together above the tank you need to snip this before anything will move!

we have changed from metal to plastic without dropping the tank too, as Bob said, remove the clip, and then make sure you have the van up high enough to be able to manouvre the pipes....... is quicker than dropping the tank, although not possibly easier!

dropping the tank is dead easy, I've done it three or four times on my own, even easier if there are two of you. If you haven't dropped it before now well worth doing so you can check out the state of the tank and the associated gubbins.

thanks chaps....will pass the info on....got the plastic ones - so would seem sensible to use them.

did anyone have to make the holes in the chassis larger?

oh - how high does it have to be up.....we are talking kerbside here....but have ramps and axle stands? (which would be better? I am assuming (naively?) that you pull 'em out of the back of the van?? Or would you disconnect and remove rad, pull pipes out forwards, and refit pipes then rad?

Can also park one side one the kerb to get that extra bit of lift. Van not lowered by the way.

thanks for the confidence booster. Have most of weekend to tackle it....with help on Sunday!

why does that seem so eminently sensible!!

ok - In the garage of bits I have a spare metal filler and a spare plastic filler. One should do the job if needed.

What else am I likely to encounter / worth changing for a good job?

thanks folks

oh - now for the really daft question...

The guage is showing about a 1/4 tank if it is to be believed....can that stay in or do I have to get it out.....

how - please don't tell me to suck.....
