Replace Your Fuel Tank Sending Unit with the Columbia SC Auto Repair Pro

A worn out fuel tank sending unit can cause any driver a headache.  While some will head in to a reputable auto repair shop or mechanic to have the work done, it isn’t always a necessity.  If you’re mechanically inclined and able to follow instructions, you can likely complete this job on your own.

Tools for the job

You will want to gather screwdrivers, both Phillips and flat head types, a hammer, open end wrenches, and the new fuel tank sending unit you will install.

 

Find Your Fuel Tank Sending Unit or Fuel Sender

In most vehicles, this isn’t as involved an auto repair as you might first think.  Start with your automobile’s manual.  The fuel tank sending unit is often positioned beneath the back seat, but it is still just as do-able if it is located under the carpet in your trunk.

 

Mechanic’s Safety Warning

ALWAYS start with disconnecting your negative battery cable!  This is done to ensure that no electrical sparks can occur.  You will be working in an extremely flammable area and MUST take all proper safety precautions.

 

How to Disconnect your Negative Battery Cable

Start with one of your wrenches on the outside nut of the negative battery cable.  You may need to place a second wrench on the opposite side as well.  Turn the nut counter-clockwise until approximately 1/16-inch from being off.  You should be able to get the cable loose with a slight twist.  If it is still stuck, you might want to try placing a flat head screwdriver into the gap above the bolt, and then gently pry it open.  Be sure that you DO NOT pull the terminal right up off the post.  This could result in serious injury. 

 

Accessing your Fuel Tank Sending Unit

The fuel tank sending unit or fuel sender is located on top of your auto’s fuel tank.  You usually access it by going under the rear seat of the car.  In some vehicles you will have to access the fuel tank by looking under the carpet in your trunk.  Once you have found your access point, you will find an access cover that is protecting the fuel tank sending unit.  The cover will most likely be secured by some screws.  You will start with lifting up either the back seat or carpet in the trunk.  Find the access cover described above.  Once you have found it, simply remove the screws securing it and remove the cover.  You are now looking at your fuel tank sending unit.

 

Removing your Faulty Fuel Tank Sending Unit

The fuel tank sending unit should have a wiring harness that is plugged in right on top.  Unplug the entire harness and just move it off to the side.  If you sending unit is secured by screws or bolts of some kind, you will need to remove those as well.

There are a couple of different ways you fuel sending unit may “lock” into place.  Many use the twist-lock type.  There will be visible notches around the edge.  You can put the tip of a flat head screwdriver into one of them and then tap it in a counter-clockwise direction.  Once it has rotated loose, you will need to very carefully remove it from the gas tank.  It will have a long rod with a float attached, so don’t just jerk it out.

 

Install a new Fuel Tank Sending Unit

All that is left now is to replace the old unit with your brand new fuel tank sending unit.  Follow the instructions backwards now to re-install all screws, nuts, bolts and access covers along the way.  Don’t forget to plug the wiring harness back into the new unit. 

And that is it!  You are done and once again are ready to roll.  If you have read through this tutorial and do not feel 100% comfortable with performing this type of auto repair, stop now.  We would be happy to schedule an auto repair or auto maintenance appointment at our Columbia, SC auto repair shop.  At Sanford’s Automotive Service, we ALWAYS do it right the first time!

How to Replace a Thermostat by the Columbia SC Auto Repair Pro

Among auto repairs a driver will commonly face is replacing a bad thermostat.  If you are comfortable performing mechanic work yourself, we can walk you through replacing a bad thermostat yourself.  This will only require about 30 minutes and it is a relatively cheap part to replace. It will be a simple task if you just follow basic auto safety tips and this how to tutorial.

For this job you will want to have a flat head screwdriver, nut driver, or ratchet to use for removing hose clamps and probably the thermostat housing bolts.  Double-check to ensure you have the proper sized tools too.  You will also need to have some work rags as well as a drip pan for the fluids. You might want to have a little extra coolant on hand too. It is important to replace any fluids lost during the repair.  A flat scraper may be useful when removing your old gasket as well.  Most important, be sure you have your new thermostat and gasket.

First Step: Thermostat Removal

First you must locate your thermostat. They are commonly found on top of the radiator hose.  Occasionally we see one mounted on the bottom. Place the drip pan under the work area to catch fluids that leak when you disconnect things. Use the tools listed above to disconnect your top radiator hose from your engine. Once it is loose, remove it from the engine allowing all drips to fall into the pan beneath. Next remove the thermostat housing bolts. These bolts keep your thermostat securely in place.  With the housing bolts free, remove the housing and lift your thermostat out.

Step Two: New Thermostat Installation

Usually you will find pieces of your old gasket sticking around the area you pulled the thermostat from.  Use a work rag to plug the hole and your flat scraper to scrape the entire old gasket away. This area needs to be as clean as possible before you proceed.  Once done, you will need to set the new gasket in place.  Now install your new thermostat.  Be sure that the power unit is pointing to the block.  Once positioned, replace the housing and the housing bolts removed earlier.  Be sure they have a tight fit. Next, reattach the radiator hose and clamp you disconnected in the beginning. Your last step should be to determine how much coolant you need to replace.  Be sure you add enough to bring the water or coolant level back to the area marking full.
