Running cold

My '74 Ought Two runs very cold, which really sucks this time of year. I first thought that maybe there was no thermostat, but after running a little while, the heater usually starts to blow air that is minimally warmer than the outside air. It never overheats, and the temp gauge barely moves from the blue part of the gauge. Is this an inherent part of the 02, or do I have another issue? I'm a new owner for this vehicle, so I'd appreciate some advice here.

Sounds like you thermostat is opening way too soon. Replace with a new one and report back. G

Thank you gentlemen. I'll install a new one in a few days and see what happens. Thanks for the input.

You might want to boil your new stat before you fit it just to check it opens. Make sure you burp all of the air out of the cooling system as well. You can quickly go from running too cool to running to hot!

That's not legal in Kansas, Dorothy.

Yup, and boil the new one, too. I dunno about the rest of you,

but my luck with new 2002/320 thermostats is that about 1 in 3 is bad.

This is so awesome. A forum where people actually ANSWER. Commendable, gentlemen. Thank you.

So I put the new 180 degree thermostat in and the needle moves up to approx. the middle of the gauge, as it should. I let it idle a while and drove it to make sure that it didn't get hot or anything, and all was good there. However, when I turn on the heat, same thing. I'm not really getting any warm air. I've noticed that it seems that the slider controls aren't really doing anything on the left side of the dashboard. They feel as if they are either not connected or are not moving at all, kind of the way my choke cable feels. I know that it needs replaced, so I'm wondering if that's the same issue here which would be cool because then maybe I could have a defroster!

However, a guy at the parts store told me that I may need to flush the heater core, and I also noticed that the 2002 has a heater valve (somewhere). I'm wondering if this might be an issue. I look forward to your replies, because as soon as I get this issue fixed, it's on to the Weber 32/38 dges (?) progressive carb that seems to like either a highway or city setting, but not both. For now, I want heat.

Thanks!

Could well be a heater cable or valve issue. open the hood and look at the passenger side of the blower fan. Do a search here too. Use the "site search" button for optimal results!

If the cable is broken you can actuate the valve manually ;-)

GL,

I put in the new thermostat and the needle is now about half way up the gauge as I think it should be, but I'm still not getting any heat. I notice that the slider controls on the left side of the dashboard don't seem to be doing anything. Either they are not connected or something else. I don't know if this is my problem now or not.

The guy at the parts store suggested that if the thermostat doesn't fix it then I may need to flush the heater core. Also, I noticed that the 2002 has a heater valve. Could this be an issue? Your input, as always, is greatly appreciated.

Oh I dunno the cable layout on the 74, but 73 has the upper/lower vent controls on the left, the temperature on the top right and fan speed below it.

Reach your hand to the back of the heater valve, above, and have someone move the heater controls and see if the lever on this valve moves.

also check flexible vent hoses under the dash if they cracked you won't get any heat on the windshield.
