Sounds like you have a loose or damaged hose to your heater or perhaps the heater radiator is damaged.

Check coolant leaks with a visual inspection. Clean the engine, then see where the coolant reappears. Look under the water pump. Check engine oil to see if coolant is leaking into the oil.

this could be from the heater core. When the heater core goes out it leaks....right into the passenger side floor board If it is water, not coolant, the problem could be a plugged air conditioner drain. Easily accesible from under the hood.

A coolant additive that seals some external leaks and closes off internal coolant passageways including stopping flow in a radiator or heater core. There are different products for different applications. There is a radiator leak sealer which uses "organic material" to seal leaks, and a head gasket/block sealer that uses sodium silicate to solidify under high temperature.

In the V between the engine blocks and under the plenums.It is a COMMON source of coolant leaks.

The fuse for the fog lights in a 1993 Ford Ranger is located in the fuse box. The fuse box is located under the hood, or under the driver side dash board.

on the passenger side floor board under the carpet

I had the same problem. You can buy harmless dye at an auto shop to put in so you can trace the leak's source.

Sounds like you have a bad heater core. Same thing happened to my car. Had to replace the heater under the dash. Check your coolant lines in and out first for leaks.

From Haynes Manual #36071, 1993-2005 Ford Ranger Pick-ups: Recommended coolant type: 50/50 mixture of Motorcraft Premium Engine Coolant (green colored) or Motorcraft Premium Gold Engine Coolant (yellow colored), or equivalent. The manual does not specify a particular color for a particular model Ranger. You might want to check the label under the hood to see if there is a preference for your vehicle. There are 50/50 mixtures on the market that will mix with either color.

Heater Core or Hose has been compromised? Remove Cover for heater under dashboard if Coolant leaks out Heater core / hose has corroded through Replace Core or Hose. You may need to start car to operating temperature in order to locate leak Be especially careful under dash Once Coolant lines are pressurized ! you may see stream of coolant shooting out of hose or Core ! Eye Protection should be worn !

There are several areas coolant can leak from. If by "under the body" you mean you see it is under the car but not necessarily right under the engine it could be leaking from a component on the engine then running down the frame before it drops to the ground. Common area for leaks is the water pump. There is a "weep hole" at the bottom of the pump behind the pulley.

For radiator leaks look for the following signs: The car will overheat Coolant level will frequently drop Pool of coolant or water under the car radiator Obvious leak noted from radiator on starting the car Faulty radiator cap causing the leak

you may have a head gasket leak. And check under your car for fluid leaks. A head gasket leak is serious get it check out immediately.


Two possibilities:There is an air pocket in the heater core caused by low coolant, the 4.7 V8 is prone to loosing coolant and not having a visible leak.The Air conditioning drain is plugged and there is a bunch of water in there sloshing back and forth

the egr is located on the right side of engine under the exhaust manifold. it's about 20"lone it see if it leaks look for wight trails of coolant.

one option is that the thermostat is sticking, and that wont let the coolant circulate. if the coolant cant circulate, it will overheat the engine. also there could be a plug in the line somewhere which also will not allow the coolant to flow properly. If there is a plug, it can be dislodged by accelerating hard to force the coolant through. also, when the car starts to heat up, check under the hood to see if the fans are running. If all fails, check for intake manifold gasket leaks, hose leaks, and oil leaks, Be sure all fuses are working and in good condition. Simple overheating conditions are usually caused by bad fan fuses. You'll know if the fans are working when the A/C is turned on, If the fans Do Not turn on then it needs to be checked.

Coolant is added to the plastic reservoir under the hood.

With the hood up and facing the engine, look to the coolant reservoir, under it is a quick disconnect which houses the sensor. If you disconnect this you will see the radiator/over heat signal flashing on your dash board.. hope this helps.

Coolant leaking from the heater core.

Probably the one that is leaking. The metal tube that runs front to back under the intake manifold is known to rust out and leak coolant out the upper back end of the engine. The intake manifold must be removed to replace that tube.

I'm not a mechanic / technician but I BELIEVE the fuel pump inertia switch on a 1993 Ford Ranger is in the front passenger footwell , under the front edge of the carpet , mounted on the toe board just to the right of the transmission hump
