Ok thank you guys, coolent level is not low. So I guess to start I will empty and try to refill to make sure that I do not have air in my system.

But why if its head gaskets would the heater fan studdenly stop? Or thinking is sepporate problems that just look like they are together? Also I have checked and found no "bubbles in the overflow tank" that others are suggesting would be a sing of head issues, no oil in water or vise versa

Ok so here I am again and getting driven insane!!! I love my subaru but am ready to trash heap it! lol 1991 Legacy Wagon intermitent overheating Fluids look great, thermostat replaced twice by me, newest being OEM, Not losing water/coolent, yes the car is actually getting hot so not just the gauge, fans come on when ever I check for it, but a new development, this last time that it overheated for no reason the heat/ac fan inside the car sudenly stopped working! All fuses that I know of are fine ( both under the hood and under the dash). So for the upteenth time yesterday it over heated, refused to cool off even after letting it coolf or a while and restarting it, so I left it sit overnight thinking I would have it looked at today. Instead I thought I would try to see if it would run, and *poof* not even hint of overheating on the 10 mile drive home!!! Could all of this be due to a bad computer? or would a bad heater core poss cause this? Help!! lol

that is a good question! hopefully someone can tell us cause now I wanna know! LOL

Thank you John, I am quite sure that my problem is cheap parts and that replacing the thermostat with OEM will fix the problem. I appriciate the how to burp! Refilling cooling systems is not something I do well ( bad experiance with an old honda accord that had a closed system) lmao. So seems I just need to get my parts and do it to it. Thank you so much for your help

LOL @ Will not fix head gaskets!! really? are people that brainless?

I have also been concernd with the over heating causing damage to the heads, so far I have found no oil/water mix. And yes I do normally have coolent/antifreeze in, a 50/50 mix of water. and thank you for letting me know about filling the engine first, That I had not heard but will surely do as soon as I get the thermostat replaced (for the last time I hope) lol

Thank you guys! Thats kind of what I figured but in calling around the stores here all they would say is "A thermostat is a thermostat". I figured it had to be that they just were not the right ones for my car. Fairtax, I replaced the thermostat the first time because the car over heated when it was full of water, so safe to assume that the water is not getting to the engine, only 2 resons for that, 1 a blocked radiator, or 2 a thermostat, since the thermostat was cheaper I started there. After removing the thermostat I then tested it ( In a pan of boiling water) and it of course did not open, which (along with the over heating being sloved) told me that I had been correct in starting with the thermostat. Of course at the time I thought it odd that what looked like a new thermostat had gone out. But chalked it up to bad parts, so called parts store, got a new thermostat, installed it and it worked great for another couple of months. Untill today that is, when I fould myself stranded on the side of the road with an over heated car again. So I decided that before I went through the trouble of replacing the thermostat again, I would find out from people who know a bit more then I do about it, what I SHOULD be putting in there. I dont mind paying the extra to get the correct one, and will call tomorrow to the dealers and see if I cant get an OEM thermostat for it The reason why I dismiss the blocked radiator also is that my fluids are clear. There is no sign of deteriation or durt that could build up in the radiator. If getting the correct thermostat does not solve the problem, *sigh* I will have to turn to the radiator. Thank you again!!! MizzJesi

Hi Everyone! I am new to the forums and so glad to have found it! LOL I recently perchased a 91 legacy wagon that I love , but since buying it, 4 months ago, it has destroyed 2 thermostats. Has anyone heard of this before? Is there a specialised thermostat that could help? I realize that I dont HAVE to have a thermostat, but would like to have one. I was told about the "failsafe" thermostats, anyone recommend or not recommend those? thank you to anyone who can help me!! Im at my wits end here. Lol
