fairway2002 Posted March 10, 2015 Report Share Posted March 10, 2015 I have a Freightliner C-7. I drains radiator to changed the lower radiator hose. Tested coolant and it is in great shape. So how do you refill? It has no radiator cap. Do I just keep filling reservoir? Thanks for any help. Link to comment Share on other sites More sharing options...

Barbaraok Posted March 10, 2015 Report Share Posted March 10, 2015 Your reservoir doesn't have a cap? So no pressurization of the system? Barb Link to comment Share on other sites More sharing options...
fairway2002 Posted March 11, 2015 Author Report Share Posted March 11, 2015 Yes the reservoir has cap and fill cap. Thanks Link to comment Share on other sites More sharing options...
Jimalberta Posted March 11, 2015 Report Share Posted March 11, 2015 Actually my MH has no rad cap either. There is a coolant tank with a pressure cap on it so that would be the same....fill the tank. Link to comment Share on other sites More sharing options...
Ray,IN Posted March 15, 2015 Report Share Posted March 15, 2015 If yours is made like mine, buy a clear hose and a funnel, and get a ladder to replace the coolant. OH, and someone to hold the funnel steady. There should be a place to allow air to escape while filling the cooling system, I can't remember where the place is though, but I think it's mentioned in the engine owners manual. A side note, all the hoses are the same age, exposed to the same elements. If one requires replacement, do so for all of them or you may soon be repeating this.

fairway2002 Posted March 16, 2015 Author Report Share Posted March 16, 2015 Thanks for the help. I did just pump coolant back into reservoir . Did not need to start engine to get all coolant back in. I did test coolant a couple times with test strips. Link to comment Share on other sites More sharing options...
