Rad fan - Mine has two hose inlets

[dickspanner]

Putting this question on here as it may get lost in my modified thread.


I am currently having water works problems and when looking at my rad fan I noticed it has two what appear to be outlets as though a water pipe (20mm ish) can be plugged in and it would possibly act as a electronic water pump.

Sorry I do not have a piccie but if required I will take a piccie tonight.

Does anybody know if this is indeed true and the back section of my rad fan is a electric water pump/circulation aid???

Perhaps someone's fitted a front-mounted oil cooler like Simon 'Brickwerks' sells ? Don't you have a Cossy in or something ?

[dickspanner]

Yes I have put a cossy motor in the crewwy but the front rad and fan is stock. It was only last night when I dropped the spare wheel holder to feel the rad pipes I noticed the cooling fan had these outlets on it, I did not have my camera so I could not take a piccie. Its like you plung one of the heater hoses in via a split and when the fan kicks in it also help mover water around the heater circuit?

If that makes sense.

all the rad motors have these bosses on they are for air circulation to cool the motor not water I believe, in some applications there may be some ducting and hose to supply air but in the T25 that's not necessary

[billy739]

arent they only on the turbo diesel motors?

but yes they arent used on a t25

[dickspanner]

Thanks for that, I am going looking at an inline water pump this morning which are fitted to Jags to see if this will help with water circulation.

Will keep you posted.

cant see why your having problems unless you have connected the pipes wrong or have air in the system.

its a myth that pumping the water to the front of the van will cause circulation problems!

i had a v6 3l in the back of my bug and have fitted vauxhall motors to bays , none of which had problems.

make sure the stat and pump are good .

was your van originally a petrol or diesel? if petrol you have done away with the old cooling except 2 heater pipes and 2 rad pipes? expasnsion tank will fit between outlet on stat housing and bottom hose . that should be it from memory

[dickspanner]

I am going to ask a real skool boy question here to to reassure myself.

Should the hot water from the thermastat discharge be fed to the top hose of the rad and water in to the engine (from Rad) should be fed from the bottom of the rad?

Then on which of these two pipes in the engine bay should the expansion tank be connected?

Double checking my install.
