Bbb Posted December 26, 2021 Share Posted December 26, 2021 So there is a small radiator line coming from the top center of the radiator going maybe 18 inches to.the top of the block, and leaking like a sive, is this anything specific for a replacement?? Or a good ace to start looking for parts?

phildirt Posted December 27, 2021 Share Posted December 27, 2021 That is AirEquip hose - the fittings are made to be taken apart and reused. Brush them on a wheel, lock the swivel is a vise and unscrew - backward thread to get the fitting out of the hose end. The fitting will have the size stamped in it. 2 Quote Link to comment https://www.bigmacktrucks.com/topic/68980-radiator-line-89-mack-with-a-425-cat/#findComment-485973 Share on other sites More sharing options...
Joey Mack Posted December 27, 2021 Share Posted December 27, 2021 (edited) totaly re-usable.. if you used a 3/4" wrench to take it off, the line will be a #6.. The fitting is #6 JIC... the number should be stamped into the fitting on one of the flat's... jojo Edited December 27, 2021 by Joey Mack More content needed Quote Link to comment https://www.bigmacktrucks.com/topic/68980-radiator-line-89-mack-with-a-425-cat/#findComment-485974 Share on other sites More sharing options...
Hans Remmers Posted December 27, 2021 Share Posted December 27, 2021 Hose is 100r5 AII air brake hose and fittings are reusable if they will come apart. Not always the case when they look that weathered. Better to use that hose than to have one made from a crimped hydraulic hose. 2 wire hydraulic is bulky and heavy and not as flexible and doesn't hold up as well under the hood as air brake hose. Air brake hose was used for air, fuel, oil and coolant lines on all manufacturers for years. Fleetpride carries hose and fittings if have the right counter person. Hose is listed as 201-6 if 3/8", 201-8 for 13/32" 1 Quote Link to comment https://www.bigmacktrucks.com/topic/68980-radiator-line-89-mack-with-a-425-cat/#findComment-485976 Share on other sites More sharing options...
