Whats this water wetter stuff im hearing of

 

i have not tried it myself [ yet ]

i have been told it is supposed to keep the water from reaching such high temperatures, if only a little

 

ok heres a wee update.....

intercooler off...


rad off....


by the way , anyone know why there is ia hole on my turbo , and where that plug goes ??
hole.....



plug...

 

any one ?

 

this is how close the fan is.....


and this is now from the front without the bumper/spoiler on...

 

and finally.....



just needs a good clean now , and a good drive to see how much better the average temp is now

 

what ones better ?

old.....


or new

 

i have a q , is it ok to mix water wetter with antifreeze ?

im not sure what way to tackle it , as i was fixing to mix up some antti freeze with water 50/50 ,and i have the water wetter as well ??

 

That plug is for the reverse light's mate.It go's on the gearbox just to the left of the oil plug thingy You'll see where it go's

Looking good

 

thanks stoo , but i already have revers lights ?

maybe as the loom is 4x4 its not needed anymore,.

 

Yeah that plug defo goes on the front of the gearbox mate, nice rad by the way

 

thanks, the plugs still not plugged in anywhere , i have reverse lights so i guess its not used , i have a 4x4 loom so i guess its just leftover or something.

thanks for the feedback too guys....

 

Do u have a similer plug on the front of your gearbox then
Where abouts in essex are you mate?

 

im 40 mins from haverhill

based on the m11 between j7 and j8

 

When my cars on the road i'll pop over and have a look at ya motor i love combi vans

 

sure, mines still being run in right now, and in 2 weeks time i have another job to do that will make things a lot better

 

The "hole" on your turbo is for the water feed
The turbo you got is the tbo355 which is water and oil cooled, the S1 turbo (tbo354) is on the hand not water cooled.
You could run it without water but I would suggest running water.

Example
This is a S1 turbo


And this is a S2 turbo, notice the water pipes..

 

where does the feed come from ? and why would it have been left off ? , i dont want to add water then later find out that there is a prob with the turbo and the water and oil have mixed ?

can anyone tell me where the water feed comes from and how i should correctly configure the water cooling on my turbo unit ?

 

The water and oil will not mix because the housing you have is made so that it is oil AND water-cooled. The standard S2 hose from the rad to the thermostat housing has a small outlet that goes into the big 90 degree pipe.

In this picture you can see the water hose has a small outlet and that goes to the big 90 degree bend pipe. This is where the water runs into the turbo


You need the pipes and bolts off a S2 turbo unit. But if you have had the hole in your turbo for a long time I would flush it to be sure that no foreign objects are in there and could go into the rad.

 

ok so where is the outward water pipe on the turbo, im keeping up so far , i know that the hole is for a feed, so where will the water come back out from, or should i disconnect from the return on the rad and flush that way >?

 

my pipe has no such feed, it goes right from the rad to the therm, and its a samco pipe ? ,im now confused,

now im going to sound really dumb, if the water feed is where that hole is, then where is the exit hole / pipe ?

 

The is a hole on the other side of the turbo aswell.
Im gonna go get my old turbo bits and see if I can illustrate it.. brb

 

On the other hand, if you add the watercooling to the turbo you would help your turbo to an easier and cooler life, but your water temps would go up.

 

ive just add an alloy cooler, id rather have the extra water through the unit than not , am i likely to damage the turbo with no water feed?
