Anyone have a view or an opinion on the effect of a rad guard on cooling? Some of the guards seem to block a good percentage of the radiator and does this affect cooling, particularly in higher temperatures? Also, are mesh type guards more efficient?
I have a guard on mine like the one in the NC700 pic. Its been on pretty much since I got it in 2012 and I really cant remember if it runs hotter. Its run fine all the time in any weather even in this hot spell or when I've been to Europe on it. Its worth it to stop stones getting in there. Mines a Beowulf one
A guard is definitely worth the peace of mind for me regarding possible damage. However, i’ve been more aware in the recent very warm weather how the engine temp soon climbs and it got me thinking more about how a guard might be affecting the cooling.
on 40-45deg days in traffic, it will do that regardless of radiator guard.
but if it does it cruising at 100km/hr... not ideal
i think modern cooling systems are so good that they either just work, or something wrong and they go pop
plus it's a lot about keeping your oil from burning, so if oil is good.. radiator is doing it's job...
It's not so much the oil Burning but breaking down under excessive heat.
Fully synthetic oil is good for 140 degrees at least before failure. However it's better to use 10/50 rather than 10/40 as a slightly larger range I guess.
