the engine in my 93 will not heat up changed thermostat and that didnt help. the gauge is reading low barley moves and the heater is only blowing luke warm are. all started after i toped it off with antifreeze the last service. Im at a total loss thinkin nabout putting a mechanical gauge on it to get a better reading but there is still a problem somewhere. any help would be great.

 

what theromstat did u put in? if it is not ford or international they will not work correctly. the ford and IH ones have an external bypass.

 

thanks dieselcrawler thats the same thing a buddy told me today
