If your not losing coolant its either a blockage or bad waterpump and more than likely its the water pump

Why is my 98 ford ranger blow super hot heat out of the vents when the heat is turned of also its overheating why?


Two different issues. The vents and hot air is caused my a cold air mixture door motor gone bad, it's very common. Replace the blend door motor to fix that issue. Overheating could be caused by many things including non working coolant fan, bad t-stat, bad water pump, low or leaking coolant or excessive buildup in coolant system.

You'll have to remove the radiator (it isn't that hard) and take it to a Yellow Page listed radiator repair shop...Be prepared to spend $200, less if you're lucky...Don't forget to put water pump lube (NAPA #13 - looks like milk) in the radiator after replacing the fluid 50/50 mix

'90 Subaru Legacy overheating....


cool air and overheating point to low coolant level. Do you have a bleeder valve near the thermostat? You may have air trapped in the system. If no air trapped, the radiator may be plugged up not allowing proper circulation of coolant.

The heat in my 1992 Jeep Wangler is not working.


The only reason it won't blow hot air is because the water is not getting to the heater core. Check to see if you have a heater control valve in one of the two lines to the heater core. If so check to be sure that is is opening and closing. If it won't open then you get no water flow in to the heater core.
