    I have checked the valve in the engine compartment near the radiator this needs to be open for hot water to go throught heating radiator...but still no heat... any suggestions?

    If you've verified that the control valve is opening/closing correctly, then you must have a blockage elsewhere. Does the "hot" line exit the cyl head(s) via a screw-in fitting? (I was/am surprised how little tech info is shown in your OM.) Sometimes such fitting's ID can corrode up from galvanic effects -- just a thought... Does the hot line feel reasonably hot near the (hot) engine?

    Did you check to see if the secondary valves are really opening? The cables can be loose at the lever and the valve can be stuck. Mine makes plenty of heat but even when everything is proper control is not so great.

    Malcomb... mine is the same. The levers work smooth and easy and it will blow plenty of hot air into the cabin.... but the line between cool air and HOT air is very fine. Seems to be either not enough or way too much. I end up fiddling with it a good bit..... or just letting it blow hot and cracking a window! Ahhhhhhhh the joys of old cars.

    I haven't got a clue about the Daytona cooling system layout, but could it be something as simple as air in the heater core preventing the water from circulating?
    If the system is not bled after a low water level situation this could be the result.
    The first signs of low coolant level are often lack of heat in the cabin.
