Gday My recently purchased lmm engine 2500 silverado heats up almost to the mark between 210 & 260
then the fan roars and returns back to 210 It only does it on long uphills when towing my 3500 kg caravan
Which i think you call a travel trailer My question Is this normal for this model?
Any advise would be greatly appreciated As information on this model here in australia is hard to find
Thanks in advance Bob
