I may have found the problem, my upper radiator hose is leaking so the hot anitfreeze has been leaking for some time. Maybe the new hose will help the heater be stronger.

well it'll be good to get that leak fixed, but unless the coolant was getting low enough from the leak to effect the heat, i highly doubt it will make your heat work better.

I personally don't think thats the problem, as 185 is enuff for heat *not like extremly hot, but still hot*. In my 83 delta i got the 160 thermostat in the because i personally didn't like my temperature getting above 200, with this 160 thermostate, it stays around 140-150, and it puts out enuff heat to keep me warm just fine, but not like sauna hot, but thats at 140, yours goes up to 175. i mean, there REALLY isnt that much difference between 185 and 195 as far as heater goes. my 15 cents

Well i dont know what the hell is the problem then!!! Its been very cold here lately, and if you have the car running for over an hour, the heat will start to catch up, and the car will be slightly warmer than it is outside.

But for the price of a thermostat, Im going to change it anyways. After that though, like you said, 185 should be plenty hot enough to heat me. I guess I flush the core next.

once you get it warmed up, try feeling the heater hoses. if one is hot and the other is cold (or just noticably cooler) you have a clogged core.

will do man, thanks! I'll give it a shot!
