woodylmiller Posted August 4, 2021 Share Posted August 4, 2021 I am trying to find the coolant filter on my ISM500. I can find the part number for the filter, but I can not find where they put it. Please give me a clue where to renew my search. There is a filter on the roadside area with a gage that lets you know when to replace it, but I think that's the hydraulic filter. That filter is located above and to the left on one of the fuel filters and to the right of the tag axle air pressure regulator. I have looked everywhere around the radiator, but nothing, unless they really did a good job of hiding it. Thanks.

Frank McElroy Posted August 4, 2021 Share Posted August 4, 2021 You likely don't have an engine coolant filter but if you do, it should be on the same side of the engine block as your oil filter. Link to comment Share on other sites More sharing options...
Dr4Film Posted August 4, 2021 Share Posted August 4, 2021 (edited) Based on photos of a Cummins ISM Engine it should be next to the oil filter toward the transmission. Edited August 4, 2021 by Dr4Film Link to comment Share on other sites More sharing options...
Ivan K Posted August 4, 2021 Share Posted August 4, 2021 That's right, mine is on the engine side just a bit above and forward of the oil filter, ISM 500. 1 Link to comment Share on other sites More sharing options...
Gary 05 AMB DST Posted August 4, 2021 Share Posted August 4, 2021 In my 05 Ambassador owner's manual it gave a replacement time for the coolant filter. Couldn't locate the filter. While in Elkhart, stopped at the Roadmaster chassis factory and asked the manager about it. He told me that the EPA eliminated it for 2005 because it was a environmental hazard. Showed him the owner's manual and he said that the manual is carried over year to year, the elimination of the fuel filter was missed.
