xoomer Posted January 10, 2010 Share Posted January 10, 2010 Ok, So I have been doing this round about with my Brat on heat first it was this then it was that now its this.. I have heat now! on the passenger side:-\ And warm to body temp air on the passenger side. have checked the Flapper for the outside air and that gave me heat finally. I had to pull the Heater control valve because it was leaking. But I have another one, my friend says put it in and it will slow the flow of the coolant in the heater core so that I have good heat.. I'm a bit hesitant to put it back in. I was thinking I should replace core. then put it in. I'm slowly putting this together. But I would like to be able to check off the Electrical, and start working on the interior, like new carpet and getting the seats cleaned up.. as well as working on rust so I can put my new doors on. Anyone Got suggestions? Link to comment Share on other sites More sharing options...
GeneralDisorder Posted January 10, 2010 Share Posted January 10, 2010 Changing the speed at which coolant flows through the core will change nothing. The temp of the coolant is maintained by the engine's thermostat and the heater core is just another radiator - keeping it hot means flowing coolant throught it as rapidly as the core can take it. Think about how the later core's work - they don't even have a valve like the EA81's do. EA82's and Legacy's, etc just have a straight-through core design and they route the air either through or around the core depending on the selected mode. But coolant always flows and there is no valve restriction. The speed of the coolant flow would matter IF You were trying to use the core as a radiator and trying to reject heat from the coolant. You don't care about that though - just about having the core hot at all times so the air blowing across it is hot. More coolant flow is better here - not less.

Txakura Posted January 10, 2010 Share Posted January 10, 2010 this is slightly related to some grief I'm having right now before you go through hoops, didn't look at your winter location but... cut up a garden hose and clamp it to both sides of the core and flush the crap out of it and see if that helps I think that is worth a try and beats the hell out of working under the dash Link to comment Share on other sites More sharing options...
