You Can Flush Your Money Down the Drain...or You Can Flush It Yourself

Okay, the last time we met, it was October 2011 and I had just suffered a $600+ setback due to a leaking master cylinder in my brake system. After that, things were relatively smooth with the truck. No major issues, regular oil changes, and so on and so on.

Remember that time that I said there is no such thing as a simple oil change, though? Well, here we are: July 20, 2012. I go it to a local shop to get my oil changed. I go there because they offer the infamous $8.99 oil change without the bells and whistles (i.e. no multi-point inspection, no topping off of fluids, etc). I've been told the same old thing regarding Francis since having her oil changed at Goodyear that she required a lot of routine maintenance that I could not afford, so I just wanted the oil changed.

After waiting around for approximately 2.5 hours for a "simple" oil change, I am handed a bill for $16.00 (because there are $5.87 of "Misc. Charges"). And then, the guy hits me with this: "We highly recommend a coolant flush. It would take about one hour and it only costs $99.95. Whaddya say?" Well, of course, I'm just a simple lady with a simple lady mind and have no idea what a coolant flush entails or why it's necessary to have one. Enter the scare tactics: "We looked at your coolant and it's really sludgy. This could lead to a lot of problems if left untreated. You could be driving down the highway on your way home after this and BOOM! Your radiator dies or your engine goes ka-put! So, for $99.95 we can give you peace of mind, and little lady, that's not too much for peace of mind, is it?"

Okay, maybe he didn't say the last part and call me "little lady," but he was very urgent and salespitch-y. I politely decline at this point because I've already been there over 2 hours on my day off and I have tires that still need rotating and time to relax. But, I gotta tell you, he scared me a bit. I almost gave in, but I was struggling financially at the time and couldn't spend more than the $16 on the oil change.

Sidenote: Be aware of auto repair shops that offer services for little-to-no cost. They lose money on these services, but they will inevitably find something wrong with your car during the little-to-no cost service and highly recommend more services or parts. There is a place here in town that is notorious for offering "Free Brake Inspections" and then recommends almost every time that the customer have new brakes installed, even when their brakes are perfectly fine.

So, I got my tires rotated down the street for fairly cheap and then went home to do a little research. Come to find out, flushing your coolant is a very straight forward task. I did an online search to see what it all meant. This diagram shows your car's cooling system:

I also found many helpful videos on YouTube on how to do a coolant flush. Here are a few of the videos that really helped me:

Probably the most helpful of videos

These are a series of videos with step-by-step instructions that are easy to follow, although I did not use the flush kit that was recommended in here. Mainly, I used the video to get my bearings with the hoses and what-not that are under the hood. Also, I have a special place in my heart for Nathan.

You will find that I adore Scotty Kilmer. He makes everything seem so easy and I love his attitude and quirkiness. I think what I like most is that I see how he just rips hoses off and tosses things around, so I feel a little more comfortable about not screwing too much up.

So, as you can see, it required very few items and no actual tools. This was great, because I didn't have many tools at the time. Here's what I used:

• 1 Gallon of Antifreeze/Coolant (not the 50/50 kind...it's a waste of money because you're paying for watered down coolant. You can just buy a gallon of distilled water and mix it yourself with 50% coolant and 50% water.) = $9.00
• Prestone Super Flush = $4.00
• Bucket or Oil Pan = $3.00
• Funnel = $2.00
• Distilled water = $1.00
• Garden Hose
• Rags

The whole thing took about 2.5 hours. It should have only take an hour or so, but I was new and timid to working under the hood. I hesitated many times and tooks breaks to go back and review the YouTube videos, as well as drink a lot of water. Messing around with your truck in the middle of a Texas summer with no shade can lead one to be ridiculously thirsty and fatigued. But I did it! I performed a coolant flush on my truck! Also, at this point, I still didn't know how to change a flat tire or even take a tire off! But, I flushed my coolant!!!!!

So, how do you tell if your coolant needs to changed and/or flushed? Well, depending on the type of coolant your car takes (this information can be found in the "Specifications" section of your vehicle's owner's manual and/or repair manual), the color of the coolant (also called "antifreeze") should either be a neon green or a neon orange. My coolant in the reservoir (the plastic container that holds the coolant when it is not being used in the radiator) was a nasty, brownish green color. It was really dark and smelled pretty bad.

This is about what my used coolant looked like.

This is the color my coolant SHOULD be...and was after the flush.

Now, looking back at the videos and knowing what I know now, I think I need to re-flush my coolant. Because I was so timid and scared to start disconnecting hoses, I missed a few steps. I didn't back-flush the system. I didn't change out my thermostat like I should have. A thermostat can be found at AutoZone for as little as $4.00 and only $1.50 for the gasket. DON'T FORGET THE GASKET when replacing your thermostat. It's just a little felt gasket that seals the thermostat.

However, even with my minor mistakes, I could tell (and can still tell) a remarkable difference in Francis' performance. I think I will properly flush my coolant sometime soon and take pictures of the process for you all. It still bothers me to this day that I missed a few steps. But, this experience sure did build my confidence and it was after this that I felt I could take on most maintenance that my truck needed! 

Things to know:

1. NEVER open a hot radiator cap. Wait for your car to cool down before messing with the radiator. A hot radiator cap could spray ridiculously hot coolant on you and cause severe burns.
2. Keep track of any maintenance performed by you or your mechanic. It will help you figure out your maintenance schedule later on.
3. Most of the employees at auto parts stores are very helpful and love to answer questions. Don't be afraid to ask. They are there to help you. And I'm sure they have heard crazier stories than yours.
4. Remember to properly dispose of used coolant. It is extremely harmful to animals, people, and the environment. Put your used coolant in an empty container that is clearly marked and then take it to your local Jiffy Lube, AutoZone, or other participating shops that recycle these types of fluids. Earth911 is a great resource to find out who recycles what fluids and parts in your area.
