no heat

[121]

Hi all, just found this forum and LOVE IT! :-) I have the same issue. I live in Sweden and picked up a 1988 121 a few weeks back. On the 250 km drive home from the seller in -15 Celsius, the heat inside the car was so bad that I could hardly tell whether the cabin air flow was cold or hot. It just about kept the windows clear; temp gauge just moved slightly above the lowest mark. Got home, replaced the t-stat for a "Nordic conditions" variety and took a test drive. Somewhat better but still only pushing the temp gauge needle to somewhere between "cold" and "normal". Next step will be ignition adjustment, flushing out the cooling system and see what that does.

Here's a question though: My car seems to respond very bad to throttle action on higher RPMs. - she's coughing like hell when I slip her some gas above 3000. She also seems very thirsty. My theory is that for some reason the automatic choke doesn't shut off, continuously giving ther engine to much fuel. Any thoughts on that? Thanks in advance guys, great forum! Big up from Sweden!

Moved this to your own thread instead of high jacking someone else's..... Might get more attention this way too

Welcome to the forum!

Is it carbureted? I'm guessing it is since it's a 1988. Be sure to run gas anti-freeze then. Good idea with EFI too, actually, considering where you are.

Let the car warm up to normal operating temp before driving it. Cover all the openings in the grill and bumper. Put a piece of cardboard in front of the radiator. These should help a lot. You will not get heat out of the dash vents BTW, due to the design of the heater box; only defrost and foot have heat.

The coolant may not be circulating well either through the radiator, the engine block, or the heater core. Do a complete cooling-system flush. Then do one specifically for the heater core, in both directions; i.e. pull off the two hoses and run a garden hose through each of them in turn. You may not be able to get to this before the winter is over, depending on the resources you have available to you, but at least do the other things mentioned, and that should help.
