Guys, 

 

I've read so much on here regarding radiators and which ones to go for, and I guess I wish I hadn't as i'm now even more confused. 

 

Obviously the mechanical fan was designed for the job, and i've never had problems with over heating but just thinking for the next project.

 

I was always tempted to go alloy and I've seen some with the electrical fan, which I thought would really help. 

Or even running both fans and slightly bending the inner wing to allow for the electrical fan to be fitted.

Irrespective is there a general consensus of what is now best or is it still the same as all those threads I read from 2011 

 

Additionally, has anyone plumbed in an overflow bottle? 

Easy job? 

 

 

 

Thanks

Depends on the spec of the engine, I had an uprated rad in what was my standard 1275 and it didn't overheat once when sitting in traffic for approx 45mins - 1hour at l2b. 

 

I plan to use the same rad for a fast road spec.

There is nothing to stop you adding an electric fan which is switchable from inside the cabin. This then gives you the option to add that extra bit of cooling if so desired. I have an uprated rad on my clubby with a high capacity water pump and this coped well in traffic.

Going to sound like a right idiot asking this but ... 

 

Would the uprated rad just be the High Spec 2 Core Alloy ones?

No my one is this one from Minispares

Sonikks's one is ideal or you could try the fletcher alloy rads I've heard good things about those.

I've the Fletcher alloy rad, brilliant.
Coupled with a ten inch fan on the inner wing.
Wired to a switch.

I run a standard el cheapo minispares rad with the standard water pump and a 88c thermostaton my 1293.  I'm down to a two-blade metal fan now as the plastic fan was over-cooling my set-up.  It's what you need rather what you or someone else thinks you need.

On my 1310 cc 'S' with over 100 bhp I run a standard Cooper 'S' radiator plus an electric auxiliary fan under the front wing bolted to the inner wing and manually switched.

Never had any problems even in competition in Summer. Minis don't overheat any more than any other car so long as the cooling system is in good condition.

Sorry if this is a stupid question but with the fletcher radiator do you but the sender in the drain plug hole ? As ive saw others with a sender and a drain plug.

[Coxie]

As I alway had overheating problems with minis in the past, so when i building my latest mini I fitted an up rated rad from minispares and the larger water pump pully to make the water push round a bit slower
It runs too cold now even with an 88 stat.

I'd never ever use an alloy radiator, yes, I know they are popular and probably many of the guys here may run them, but no, not for me. Cooper / Brass is fine thanks.

 

I always fit up a Header Tank (which is similar to an overflow tank) and I often ask why they didn't do this in the factory, though eventually they did. All my Minis are Clubbies so there's lots of space to fit one in on them, usually just in front of the Alternator, off some fabricated brackets hung from the body, you can see it's cap here

 

 

A few guys fit them up in the wheel arch on the round nose. The Header Tank can be fitted lower than the Radiator, once the system is filled and bled, it will work fine, just takes a while to get to that point.

Now then.

What is going on with this car?

Accelerator cable is going through the cross member not going through the bulkhead below the cross member.

And that block to the left (in picture) of the brake MC?

[Mini Manannán]

It's been Spidered! It is intriguing. LHD might explain the throttle cable?

[nicklouse]

Looks like it has two flexy clutch hoses.
Interesting stat. housing.

Think it is RHD.
