The heat in my car sucks, at best it'll blow warm, never close to hot. I don't think the thermostat is sticking open because the gauge starts to move after a reasonable amount of time for how cold it is, and by looking at this forum, it seems to be getting warm enough on the gauge. The car usually won't go but a small amount over 1/4 way unless i let the car sit for 10 min idling after it's already reached the 1/4 mark, then it'll be at half way. The entire time i'm in my car i'm cold and friends complain as well, and it's been about 20 out lately so it's not like its ridiculous out. Is it normal for these cars to not actually blow hot? Or could my heater core not be flowing right? Thought about putting cardboard over the radiator as I've seen people mention on here to help it warm up faster. How much is usually covered?

How cold is it where you are located? When my t-stat was stuck wide open it would get up to the 1/4 mark while moving and would make it 1/2 way when I was stopped.

I agree on flush. My gauge sits at a notch above 1/4 now whilst driving. Also check you coolant level as well.

Was kinda figuring it was the heater core clogged if others don't have this problem so I suppose ill flush it tomorrow. Found one guide on it. Pretty much just need an adapter. Since its frozen out I can't use a garden hose but will do a funnel and a hose. Prob just get one that slides into the heater core hose. I tried to feel how hot the hoses were the other day but even after the car was up to temp, both radiator hoses were barely warm so didn't do any good. When you guys feel your heat blow is it actually hot where it almost is burning like some cars or just warm?

after flushing mine, the air came out hot!!! i had to lower the heat it was getting so hot in the car, also you cant use a funnel and hose, need pressure, hose has to go directly into the core hose, no need for an adapter, i just held the garden hose to the heater core hose and turned it on

When was the last time the thermostat was replaced? Once they get old, they stick open and wont let the engine warm up completely. Since you're saying your engine isnt warming up fully, its more than likely your thermostat.

If you're worried about your heater core, warm the engine up and feel the 2 hoses going to the heater core with the heat off. If they feel about the same temp, the core is fine. If one hose is significantly hotter than the other, then the core is blocked.

To bleed the cooling system, keep filling the radiator with the engine running, then open the 2 bleed screws located on the engine until only water comes out. Our engines wont bleed themselves using just the radiator.

Was thinking it wasn't the thermostat because the operating temp seems to be what people have listed as normal. Its usually a notch or two above quarter. And I just bought the car a month ago so no idea when it was last changed

When you buy a used car, if it doesnt have any records, I'd go ahead and do a full tune-up regardless. I'd start with the thermostat, its cheap and a good idea for peace-of-mind.

Feel the hoses like I said, that tells a lot about the heater core.

I would drive around a little too. That's what I did too bleed my system. Gets it up to proper operating temp IMO.

Decided to flush the heater core and noticed the two hose ends that go to the motor are loose. ?. Turned out my garden hose had some water in it when it was removed and was froze. So I kept pouring water down the hoses and blew it out with compressed air. Some chunks of rust came out and I reconnected everything, this time with dif clamps to make it easier to remove again. after bleeding the system the heat is much better. Even let the car cool off for an hour or two again just to make sure it wasnt warm from just sitting idling for so long. But the heat at the 1/3 mark is as hot as it used to be at half way. half way is now third degree burn hot. The real test will be when i'm off work tonight when its much colder out, hopefully its just as warm. I didn't add any coolant back to it because i can't tell where the min and full marks are supposed to be at. i see a coolant symbol with an arrow that goes down to a line towards the bottom, which i'm guessing is the minimum amount, but where is the full amount? is it where the tank bulges out towards the motor?

Thanks for everyone's help. much appreciated
