Bad head gasket. Cracked head.
there is hydraulic fluid reservoir for the fan... it's driven by hydraulic pump... and there is coolant reservoir...
the water pump is right behind the radiator and is belt driven. Also try to check the coolant reservoir by having it pressure tested
It will bubble (soapy). remove the bottle & wash it out & top it up with the correct coolant before you drive it. If you already have driven it you should get a cooling system flush $50-80.00
There is no coolant pressure relief valve. Just have to wait for the engine to cool off sufficiently to safely remove the coolant reservoir cap.There is also not a coolant bleed valve.Here's are the coolant bleed/burp proceduresNEVER ever think of releasing a radiator - coolant cap when the engine is hot, or even warm!!!Burping: In order to what is sometimes referred to as 'burping' the cooling system - getting a big air bubble out of the closed cooling system, you will actually need to have the car running with the cap off.During the initial fill, fill the coolant reservoir bottle to the top of the cold fill range.Set the temperature blend selector to the full warm position and the fan motor control to high for the front and rear heatersStart the vehicle with the reservoir cap off and allow to idle until the thermostat opens NOTE: the coolant level will drop quite a bit when the thermostat opens - that's most of the air bubble in the system being driven to the top of radiator and escaping. Without the air, there's more room for coolant.Top off the coolant in the reservoir bottle to the top of the cold fill range,Install and tighten the reservoir cap.Increase the engine rpms to 3,000 for 15 seconds, and then return to idle for one minute.Repeat the previous step four times or until heat is coming from the rear unit while the vehicle is idling.Allow the vehicle to cool and top off the coolant in the reservoir to the cold fill range.Note: if you find the heater going cool or cold when idling, that's a good indicator you might have to burp the system again. Equally likely just adding more coolant to the overflow reservoir will suffice too.Did I mention to NEVER ever think of releasing a radiator cap when the engine is hot, or even warm? !!!
For the most part, only old cars (pre 1970s.....) require adding coolant directly to the radiator. Newer vehicles have a "reservoir tank" that can be accessed anytime. If the reservoir is below the Full line (or nearing or below the Low line....) - you can add proper antifreeze/coolant (check your owner's manual) directly to this reservoir tank.I've included the eHow article which outlines this process too....not to be confused, some owner's manuals MAY require "radiator flushing" - this is the only exception when you would add antifreeze/coolant to the "radiator" itself....and only when the vehicle has not been driven.
It's belt driven & has 2 coolant lines attached if that helps.
Generally thru the use of a belt driven centrifugal pump
On a 1995 Ford Ranger : The power steering fluid reservoir is on the drivers side of the engine It is one of the belt driven accessories at the front of the engine
Some varieties of gas turbine engines (e.g. RR Trent and RB211) have 3 concentric rotating shafts. Each shaft connects a compressor with a turbine. The low pressure compressor, or fan, is driven by the low pressure turbine. The high pressure compressor is driven by the high pressure turbine. Between the low and high pressure compressors there is an intermediate pressure compressor and, guess what... it's driven by the intermediate pressure turbine.
You either have a head gasket leaking,or a cylinder liner leaking.I can't remember if the series 60 has a gear driven water pump,I think it does, if it is gear driven it can leak through the water pump as well,( through the front cover).If it is not the water pump the best thing to do is to drop the oil pan and pressure test the cooling system.You will be able to see where it is coming from.If you are not positive where it is coming you should have the head pressure tested in case it is cracked.
Via a pressure-driven transmission fluid cooler fed by in and out hoses near the radiator reservoir. They can be as small as about 1" x 1" x several inches and resembling the guts of a radiator, finned tubes; although they can get to radiator-sized.
It is driven by a belt. Follow the belt and you will find the p/s pump if it has one. It may have manual steering. The reservoir is part of the power steering pump.
