Mykeys Toy Posted February 17, 2005 Share Posted February 17, 2005 This is a 86 Hatch.. anyway on with the Qs. When the car starts to become warm i have some heat but luke warm at best. The heat only lasts about 2-3 minutes then becomes cold. the heater core has been flushed with hose and system flush. after driving for a while (15 minutes or so) the car surpasses normal and climes half way between normal and hot and heater doesn't help. Does anyone know how to figure out whether it is the heater core or the water pump? The T-stat has been replaced recently and I have a few others I keep around to test just in case. Possibly related. Every morning especially when it's cold outside there is a whirring noise almost a whine but lasts about 15 seconds. Mike Link to comment Share on other sites More sharing options...
NV Zeno Posted February 17, 2005 Share Posted February 17, 2005 Mike, The "15 minutes or so" of driving you write of, is it city or highway? Link to comment Share on other sites More sharing options...

NV Zeno Posted February 17, 2005 Share Posted February 17, 2005 Could be your thermostat. I had similar symptoms right after I did a flush job, and installed a generic thermostat. Replaced it with a Genuine Subaru stat, voila.."Just like Downtown":grin: . (Many thanks to South Shore Motors for staying open a few minutes extra on Xmas Eve for me) Link to comment Share on other sites More sharing options...
Qman Posted February 17, 2005 Share Posted February 17, 2005 Sounds like the t-stat is stuck or sticking in the open position. Howdy Mike. Good to see you're still around. Link to comment Share on other sites More sharing options...

Turbone Posted February 17, 2005 Share Posted February 17, 2005 You need to stop by and see my new "Toy" I saw you the other day when I was on my way to work, as usual you were busy driving Link to comment Share on other sites More sharing options...
Skip Posted February 17, 2005 Share Posted February 17, 2005 since this happens quote the car surpasses normal and climes half way between normal and hot Then I am inclined to think you have a air block in the core. Get her nose high in the air with it warm and running and see if she'll burp herself. Might try putting a "flushing "T"" in one of the heater hoses. Make sure the valve is all the way open, I believe you will find this close to the bulkhead on one of the heater hoses under the bonnet. The cable could has slipped it's mooring. How come we see all these non factory T-stats in question? answer Maybe they're J _ _ K? Link to comment Share on other sites More sharing options...
Mykeys Toy Posted February 18, 2005 Author Share Posted February 18, 2005 Thanks Skip I will give that a try as well. Rob would that be th XT6 on Locust? I had to stop when i saw it for sale while on my route. Funny it doesn't look to be in bad shape at all for that price. Mike Link to comment Share on other sites More sharing options...
