Something different for a Monday!
I’m building a buggy for the road.

Would you say this mocked up radiator is too close the Driver/passenger?
Or does this location look dangerous at all?

It has an expansion tank which has an over flow pipe out to the open incase it ever overflows.

Would you keep it there or put it on the red bar behind which is about 7 inches Further back and 3 inches higher?
Bearing in mind, wherever it goes, the little expansion tank and pressure cap will have to be a little higher

Ps. mounted right at the front of the vehicle is not an option sadly

Will it go in the centre? That aside it looks fine.

Thanks, it might be the angle of the picture, but it is in the centre

I’m wondering if it would be worth having it on the red bar directly behind where it’ll be a few inches further back but a little higher?

I don't see any problem with the position, but are you planning to mount it properly?

I know it was a lengthy post.

Yes I’m planning to use thicker steel brackets

Not quite sure what you mean there?

You're going to need to protect passengers from it. Long haired passengers, passengers wearing synthetic scarves, passengers looking for something to hold on to whilst getting in / out...

Hmmmmmmmm! Rear radiators? There is a reason why most cars, even rear engined cars that are not air-cooled, have a front radiator, and it's air flow. The flow to yours will be highly turbulent, and will not go through it well.

I once built a rear-radiatored Triumph Vitesse Estate. I know, crazy! It was part of a aero experiment is the only excuse.



Massive rad, right across the back. Massive pair of truck fans. Intakes both sides (You can just see one on the left), ducted to the rad. 2" hose, electric coolant pump.

Worked fine on the road, but on the track, it consistently overheated.

Yours is a different style of vehicle! Go for it, but be ready to consider, say, a vane above the driver's head to direct flow onto the rad.

I think, the further back the better, to allow air flow into it. Anybody sitting directly in front of it will affect that airflow badly.

Plus, some protective bulkhead/or sheeting in front of it for safety if it ever splits or holes whilst being driven. The thought of any water being pressured onto occupants, especially while at road speed would be very dangerous.

And then if the airflow is virtually blocked by the protection it is going to need ducts of some sort directing airflow right onto it. Big scoops either side, directed right at the radiator. Maybe plus a pulling fan mounted behind it to assist pulling air through it.

Thanks for the replies

Just to clarify, it’s higher than it looks and it’s in the centre so there’s no chance of the occupants heads blocking airflow.

I'd fix it and run it if I were you, you won't know if it's effective otherwise and all you'll get here are stupid responses.

Well I’m not so worried about the effectiveness, more the safety/ practicality of being close to the cockpit but thanks

Looks fine to me if it's got an expansion tank and vent, not like it's a high-pressure system.

In an already unsafe and unpractical car? Ok.
It's not the 1930s anymore, radiators don't just burst out all over the place like they did on old b&w films.

I know, which is why I don’t want to make it any more dangerous or impractical haha

Do you think the engine is too close to the passengers? Spark plugs, con rods and flywheels have all been known to move away from their allotted positions at extraordinary speeds.

It's wise to try to deflect anything dangerous, metal, steam or boiling water, away from people.

Indeed, just wrap yourself up in cotton wool and never leave the house ever again. It's just too dangerous out there.
