Black Bart, I agree if it was an installation error but I think most would find it interesting that Briggs has a cooler installed on EVERY Intek ELS engine pictured in my manual, Briggs has the cooler as an aftermarket part and Briggs says buying the cooler, installing it-correctly-will void the warranty.
Kohler on the other hand, lists their cooler AND an oil filter relocating setup(it is slick) and they don't care if you install one or not, but more importantly if you install one the Kohler warranty remains intact-installed correctly that is.
This brand engine v that brand engine v another brand engine discussions will continue forever, and that is fine as it is interesting to me, and as many mention it pretty much comes down to preference/opinion. However the voiding the warranty nonsense with the addition of an genuine Briggs part on an engine which is pictured multiple times in the owners manual with that part installed is a very very valid reason to call it what it is, stupid and ridiculous-many substitute very non complimentary words for B/S, and Briggs has earned this practice.
Should anyone doubt what I type just take a look at your late model Intek ELS owners manual or, should you be fortunate and NOT own a Briggs ELS download one from the Briggs site and see for yourself, to make matters more confusing my manual even lists the cooler part number as an option/accessory-they really are ultra maroons.
