[urq] Oil cooler lines : replacement from Aeroquip

Tue Jan 13 18:29:49 PST 2009

Oh oh, I can see what you mean : the oil cooler is always under the road spray... salty stuff around here. And you tell me that now ? :-)

Should I paint the assembly with some rubberized GravelGuard undercoating ? Maybe it can protect a bit ? Or wrap the fittings into some giant shrink-tubing ?

Re Scott's comment re cracking of Aeroquip fittings.  This happened to me - 
the fittings on both hoses at the at the oil cooler end cracked due to 
internal corrosion and swelling.  Replaced with new hose and stainless steel 
fittings.
