ranchhopper Posted October 18, 2016 Share Posted October 18, 2016 I always thought those valueliners were one of the best looking trucks on the road. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/47304-1987-mack-rs-688lst/#findComment-349088 Share on other sites More sharing options...

kscarbel2 Posted October 18, 2016 Share Posted October 18, 2016 The dealer body was so upset over the end of RS-RL Value-Liner production that we introduced an all-new variant of the new RD called the "Western Contractor" which initially had a Value-Liner like grille. . 1 Quote Link to comment https://www.bigmacktrucks.com/topic/47304-1987-mack-rs-688lst/#findComment-349122 Share on other sites More sharing options...
Timmyb Posted October 18, 2016 Share Posted October 18, 2016 With two intake tubes going under the bonnet, would that mean it's a coolpower? In 1987? Quote Link to comment https://www.bigmacktrucks.com/topic/47304-1987-mack-rs-688lst/#findComment-349135 Share on other sites More sharing options...
j hancock Posted October 18, 2016 Author Share Posted October 18, 2016 This is a 688 350 HP with the CMCAC in front of the radiator. One air cleaner tube goes to the turbo and the other is a way to draw warm under hood air into the air cleaner for cold weather operation. Around 1982, most Macks were running with the intercooler out front. CMCAC is Chassis Mounted Charge Air Cooled. Quote JimIt doesn't cost anything to pay attention.
