Ford water pumps have a "weep hole" on the bottom of the water pump. When the bearings go bad the coolant will weep from there. Also you may just need to get in there with a flashlight, probably from underneath the truck and see exactly where the steam is coming from. Check all the heater hose attachments and the radiator hoses. If you are lucky it may just be a worn out hose.

If the heater core is leaking, you would get a lot of steam that would smell "sweet". That would also leave you low on coolant, which could be a source of your overheating. If it's more of an electrical smell, you may have a blower motor or a blower motor resistor going bad, but won't cause the engine to overheat.

Where is the low side port for the 1990 ford ranger


1990 Ford Ranger was equipped with an R-12 system (Unless it has been retrofitted) The low side port for those systems were usually on the suction-side reciever/drier. I have also seen upgraded hose kits installed on some of these vehicles (for retrofitting purposes) where the port is on the hose assembly between the drier and the compressor or even on the compressor manifold itself.

Sounds like you have a blown head gasket - white smoke = coolant. Pull plugs and look for "steam cleaned plug" or for coolant in oil - looks milky.

Its runnining close to hot on temp gauge and after i parked it from driving home fom work i saw some smoke coming from under the hood


If smoke, you may have a leak in a hose. When cool, check for water marks usually coming from the connection to the radiator. Another thing to do but may be dangerous is to load up the radiator with water and start the engine, let it run for about 15min for it to heat up and look for water spray. Also, when parked, is there a puddle of water under the car?

Also, I would check the water level in the radiator (never open when hot), to see if i need to add water. Don't look at the reservoir as a reference. It could be just low.

The key here is you think there may be smoke coming from the hood.

Another thing, if the radiator is full of water, then it could be your thermostat. it is usually located at the end of the top hose which runs from the radiator to the engine. In this picture, you are looking at the top of the engine looking down. This is the location of the Thermostat. If your vehicle is close to over heating, this valve could be getting stuck.

As a test, remove the thermostat and try driving it around to see if it gets close to overheating.
