Engine radiator turned the wrong way?
I have bought a Polo rad for my locost, but have a major problem !
to have the rad, in the right place, with hoses connected to the rad, and mounted far enough back, means the nosecone will not fit!!
But, if i was to fit the rad the wrong way, ie back to front, the hoses would exit at the front of the car, and will go either over the top or the
bottom of the rad to the engine,
The rad appears to be the same either way
Can anyone foresee a major problem with my setup?

Restriction in the cooling circuit. Whether or not thats a major issue you'll only find out down the line.
Potential for hoses/pipes to fatigue as they will be floating around unsupported?
More joins means more chance of leaks?

Thanks, your right on all counts, and backs up my plan to ditch the rad,
and get one made that fits what i need!

i see no problem at all just support the hoses.
if the joins are made correctly then there will be no leaks

As above, no problem at all, the water won't know any different (unless you use tight bends instead of U bends) and the air doesn't know
any different. Support the hoses and shimmy on.

We used to race landrovers with the rad in the back, all you have to make sure is that the water at the top of the head can bubble off, this goes into
a header tank so no issues that I can see.
If the pipe off the top of the rad goes up and over you may want to add a small pipe at the highest point to bled off any air back to the header tank
if you get overheating issues, suck and see first off.

That's exactly how mine's mounted.
No probs 3 years in but I do have a big Kenlowe ready to blow through the front if necessary.
Bear in mind that the most efficient rad is one that's angled slightly to the airflow as that presents more finning.
Also don't mount the rad solid - use rubber mounts (IIRC mine are Transit rad mounts) tapped into the vertical holes or the MK1 version I used
was lower brackets with holes and cushioned by pieces of cut, small diameter silicon hose as buffers then bent brackets which went loosely into the
top slots.
HTH.
Cheers, Pewe
