Chiefzon Posted October 10, 2005 Share Posted October 10, 2005 Hey USC! First time on the site and I'm trying to troubleshoot a heating/cooling problem that started yesterday. Usually the defrost on the '90 Legacy wagon is great, but my windshield started fogging up last night and I kicked on the defrost and it socked it my entire windshield in a matter of seconds. It smells like hot radiator fluid and when on hot, it physically steams, and fogs the windshield. Nothing else is out of normal, the temp gauge is a steading 1/3 as usual and the vents are still pushing heat, but with more water content and odor than desirable. Also, engine not hotter than usual (under the hood) and all the belts are in tact as well, and the reservoir has the normal about of fluid. Any suggestions? Thanx!!

tunered Posted October 10, 2005 Share Posted October 10, 2005 your heater core is leaking into the ducts,maybe a loose hose under hood next to heater core where it hooks on but not likely. ed Quote Link to comment Share on other sites More sharing options...

I have to take it in anyway for new CV Boots/Joints in the next few weeks. Quote Link to comment Share on other sites More sharing options...
NoahDL88 Posted October 10, 2005 Share Posted October 10, 2005 If you don't do your own CV's then i would bring it in, if it were me and i lived in sunny CA, i'd just flush it good with plane water, block it off once its empty, and then run a hose bypass. won't have defrost, but how often do you need it?

TheBrian Posted October 11, 2005 Share Posted October 11, 2005 You can either remove the entire dashboard (large project) to get at the heater core so you can replace it, or you can plumb the heater core out of the system. J. C. Whitney sells 12V electric heaters, though most of them are pretty weak. Quote Link to comment Share on other sites More sharing options...

1 Lucky Texan Posted October 11, 2005 Share Posted October 11, 2005 At the risk of being flamed - do any of you guys think a rad leak additive could fix his problem? (....ducking!!!!) Quote Link to comment Share on other sites More sharing options...
tunered Posted October 11, 2005 Share Posted October 11, 2005 my 85 did the same thing,got by 2 years with aluminum stop leak,maybe,maybe not,but for the cost its worth a try. good luck. ed Quote Link to comment Share on other sites More sharing options...
Chiefzon Posted October 11, 2005 Author Share Posted October 11, 2005 I got an engine replacement 15 months ago, I don't thing the heater core was part of the job, but is it possible that the tech - who seemed know his stuff- may have not fit the hose to the core back on quite so well? A full leak in the heater core is pretty rare isn't it? What every it is, its a weekend job... I think the stop leak would be an extreme last resort.
