aba4430 Posted December 30, 2011 Share Posted December 30, 2011 Folks, Yesterday, I noticed some coolant on the driveway just below where the heater hoses connect to the fittings on the firewall. The two brass (or copper?) fittings are quite thin and weak, so I have not clamped down on the hose clamps, but just tightened the clamps moderately. I can tighten more and stop the leak, but am worried that I will cause the fittings to collapse. I am thinking of putting a couple of short copper tubes (smaller OD than the ID of the heater hose fittings) within the OEM fittings to ensure that they will not collapse when tightening the hoses. Looking for some feedback on this. Are the fittings replaceable from outside the cabin. There is a rubber grommet that goes through the firewall and to the heater core hoses. Is there any slack that will allow me to pull the grommet and hose sections out and allow me to replace the filltings? Thx, aba4430 Link to comment Share on other sites More sharing options...
GeneralDisorder Posted December 30, 2011 Share Posted December 30, 2011 Don't worry about clamping the hoses down tight - they are thin but as long as they are round they will not collapse. Essentially they are round arch's and structurally you are evenly applying load to the arch.... it will take a LOT more pressure than you think it will. If it's an EA81 that you are talking about here - the fittings are part of a heater control valve assembly under the dash and could be replaced with some effort from below the dash. If it's an EA82 they are part of the heater core itself and can't be replaced seperately. GD Link to comment Share on other sites More sharing options...
