Double core radiators

Post by **yellowpinky** » Sat Nov 01, 2008 7:14 pm

I need to replace a worn out radiator in my van (1969). I was wondering if anyone could explain the benifits of having a double core radiator over the standard?? The older style high top radiators look appealing too. They just seem to be a slightly different shape, no real difference in performance??

No need for fancy double core - just get a standard one - plenty of cooling capacity there for any normally aspirated A series you care to fit.

I am hoping to eventually to take my moggy to Malta and I was going to fit a Kenlowe fan, but reading your previous comment would a standard rad cope with the warmer weather. Steve

Certainly! If any problems - just fit two fan blades - at right angles to each other for extra cooling when stopped.

The A Series engine is grossly over cooled anyway, so double core rad a waste of money, and likely to reduce fuel economy if engine cooled even more. Should be fine in Malta, just fit the lowest temperature thermostat.

Ask 'Frank' on here regularly - he's in Malta!
Wish I was in Malta right now - this winter weather is getting to me - and it's only just the beginning!

Thanks for the advice I want to keep my moggy as original as possible, but I thought with the high temperatures in the summer in Malta a Kenlowe might be needed.

As Moggy Tec has stated the moggie engine is / can be overcooled quite easily though only thing I would be concerned about running a moggie in a hotter climate is using a better grade oil than recommended as due to the increased temperature it tends to break the oil down faster and result in more engine wear if not careful and also a quality head gasket may be required
Also instead of fitting a thermostat you could fit a swirl chamber

I ran one of these in my mini with a 1275cc racing engine to reduce temp as even with a up rated radiator temp was still high

Yes - the thermostat sleeve is ok for racing - but NOT for daily use. Just use a lowish standard thermostat. Generally the 'Kenlowe' etc give poorer cooling than a standard fan - which normally overcools like mad of course - so just go with the standard fan. It will be fine !

I believe I'm right in saying that the design of these engines leads to them typically running quite a "cool" coolant temperature, but a fairly hot oil temperature. So if I were you, I'd add an oil cooler before tinkering with the "coolant" side of the cooling system.

Did this on my Midget, it's quite easy to do! The extra oil volume won't do the engine any harm either.

Just a thought!

No need for an oil cooler unless you plan on driving it long and hard on Motorway - or competition use ? I rather doubt either applies on Malta.

Malta is about 19 miles long and about 12 miles wide so not much call for motorways

This was one of the reasons I bought a moggy it will keep up with most traffic conditions and will be economical to run and repair over there. Also a bit of nostalgia from my youth.

Could be a long and arduous drive to get TO Malta though!
