You didn't state why you might do either one. If the car is overheating there are many things that can do it including but not limited to the raditor, dirty , therostae stuck closed ( heats up quickly and the raditor doesn't get hot) fan not working right,( raditor very hot and fan not blowing very hot) Water pumps leak more oven than any other failure the blades coming off does happen but rearly. The fan not blowing good and the raditor too dirtly as the air has to go though the outside and the water needs to go though all of the inside ( partly stopped up is connon. Many raditors don't flushout well if they get to the point that they don't coolwell and replacing them is a better solution washing out the rest fo the system as your work goes by..

97 chevy S10 blazer V6 4.3 temp gauge stopped working, and I already replaced the ECT sensor, still no luck, what else can it be?
Hello insta5,

There are two temp sensors, one is for the ECM and the other is for the instrument panel gauge.

The one located just under the thermostat goose neck is the one for the gauge. See picture below.

Where do you find and change a thermostat on a 1988 F250 7.3 diesel?
a108892a.gif

Section 03-01D: Diesel Engine, 7.3L V-8 1992 Bronco/Econoline/F-Series Workshop Manual
REMOVAL AND INSTALLATION Please rate highly if this helps. this is 1992, only thing I have, should be the same. Thermostat A poppet-type thermostat is used with the engine. When the thermostat is closed, coolant flows to the water pump through a bypass passage at the front of the engine. When the thermostat is open, coolant flows through the coolant outlet elbow (thermostat housing) to the radiator. ani_caut.gif CAUTION: Replacement thermostats other than the specified Motorcraft or Navistar thermostats may result in engine overheat damage. The specified thermostat does not contain an internal bypass, since the by-pass is located in the cylinder block. Therefore, whenever the thermostat is replaced, it is mandatory that only Motorcraft E5TZ-8575-C or Navistar 1807945-C1 thermostat be installed.
The thermostat is a high temperature thermostat for use with a mixture of water and permanent-type antifreeze. ani_caut.gif CAUTION: Do not attempt to repair the thermostat. It should be replaced if it is not operating properly.
Check the thermostat before installing it, following the procedure described in this section.

Thermostat Design (Acceptable vs. Unacceptable)

Removal
  1. Disconnect ground cables from both batteries. NOTE: On vehicles equipped with EEC, when the battery has been disconnected and reconnected, some abnormal drive symptoms may occur while the EEC processor relearns its adaptive strategy. The vehicle may need to be driven 10 miles or more to relearn the strategy.
  1. Drain coolant from radiator until coolant level is below thermostat. Refer to Section 03-03, Engine Cooling.
  1. Loosen and remove alternator and vacuum pump drive belts.
  1. Remove alternator. Position alternator out of the way.
  1. Remove vacuum pump and bracket. Position pump out of the way.
  1. Remove all but the lowest alternator/vacuum pump mounting casting bolt. Loosen the lowest bolt and pivot the alternator/vacuum pump casting outboard.
  1. Remove the water outlet housing attaching bolts. Bend the radiator upper hose upward and remove the thermostat and gasket.
  1. Inspect thermostat as outlined in this section.
Installation
  1. Clean the water outlet housing gasket surfaces. Coat a new outlet housing gasket with Perfect Seal Sealing Compound B5A-19554-A (ESR-M18P2-A) or equivalent. Position the water outlet housing gasket on intake manifold opening.
  1. Install thermostat in crankcase opening with the copper pellet or element toward engine and the thermostat flange positioned in the recess. If thermostat is improperly installed, it will cause a restricted flow of coolant.
  1. Position the water outlet housing against the crankcase. Install and tighten the attaching bolts to specification listed at the end of this section.
  1. Reposition the alternator/vacuum pump casting. Install attaching bolts.
  1. Install vacuum pump with bracket and tighten to specification. Refer to Section 03-05, Accessory Drive.
  1. Install alternator and drive belt.
  1. Install vacuum pump drive belt.
  1. Adjust alternator and vacuum pump drive belts to specification. Refer to Section 03-05, Accessory Drive.
  1. Fill and bleed the cooling system. Refer to Section 03-03, Engine Cooling.
  1. Connect ground cables to both batteries.
  1. Operate the engine until normal operating temperature is reached, then check the coolant level. Inspect cooling system for leaks. ani_caut.gif WARNING: DO NOT STAND IN LINE WITH OR NEAR RADIATOR FAN WHEN REVVING ENGINE.

They can get all the parts. They also provide haynes repair manuals, any special tools (probably not required for this vehicle) and any special disassembly instructions.
