We bought this car a week or two ago . 37,000 + miles on the clock . in nice shape , as far as I can tell .

So , I am attempting some DIY PM .

Considering it is 11 years old , rubber and plastic tend to go bad with age & heat . I am replacing the 2 radiator hoses . The lower hose was a real bear . Ended up removing the battery & tray to gain better access to the 2 spring hose clamps . Has to cut the OEM hose in the middle so I could treat this hose as 2 separate pieces . This enabled me to twist / wiggle the hose ends to position the 2 " tabs " on the spring clamps to be more accessible to pliers .

I do not like spring hose clamps ! Replace the ones on the lower hose with screw / worm gear type clamps .

While the battery tray is out , I wire brushed it and painted it with Duplicolor black " Rust Remedy " spray paint . Hope this will forstall further corrosion ( it really was not in very bad shape ) .

Plan to replace the serpentine belt . Replaced the 2 plastic " heater elbows " with metal elbows .

Plan to replace the thermostat / gasket . When all the coolant related items are finished , will refill with fresh / new coolant .

Used 2 different Walmart $ 2 turkey basters . One to remove Power Steering fluid & the other to remove brake fluid . Then refill with clean / new fluid . ( By the way , the PS pump is located kind of under the alternator area of the firewall side of the passenger side of the engine compartment . Very big pain to get to . :-(

Replace the hood assist " struts " .

Purchased a transmission filter & gasket . Ordered full synthetic Dexron VI & hope to do a spill & fill before the weather turns cold , this winter . Thinking about adding a Dorman steel transmission pan with a drain plug .

Tires look to be 50% or better . Dealer said they changed oil before I took delivery . Bought 5 of the $ 10 - 5 quart dino oil on sale at Home Depot . One oil filter at Wally World . Plan to order sever ( stretch out the freight cost ) filters from RockAuto.com .

Does any one know if the suspension has grease zerts ? I have a grease gun .

Thanks for listening .

Need to order a dash mat .

Ive read that the turkey baster method does not work with brake fluid. I do use the same method for PS fluid though.

How about a inline transmission filter or cooler?

I change ALL fluids as soon as I get the car home,before ever driving it again. The weekend I brought my Accord home,I changed the oil,transmission fluid,coolant,brake fluid,and power steering fluid.

Turkey baster does not remove anywhere near all of the fluid . Need to drive it a while & repeat .

Do not know why it has a problem with brake fluid ? Seems to work for me ?

Thought about an external ATF cooler in front of the radiator .

Also thought of the in line filter . Less familiar with it than the external cooler . The question of pressure drop comes to my mind . How often is it recommended to be changed out ?

Thanks ,

Brake fluid doesn't circulate .The master cylinder pushes fluid to the wheel cylinders when the brake pedal is pushed . when the brake pedal is released the pressure drops and the brakes release. Like a syringe connected by a hose to another syringe. Noooooooooooo dash mat.

Not a bad idea .

Being an old fat man , I kind of have to pace myself . Have not driven it very much since taking delivery . I mostly drive a company pick up & wife drives our little red Chevy Sonic .

Will drive it more after I retire & loose the company truck .

Thanks , :-)

Yes , you are correct , yet it would seem there must be a little migration of fluid ?

The turkey baster should be better than nothing . However , I can see the best thing would be to jack each wheel up , one at a time & bleed the wheel cylinder / caliper via the bleed screw .

The old fat man does not move along like he once die .

Thanks , :-)

The company truck cost me zero & I drive it as I wish .

I too am subject to procrastination before I start a project . :-(

The water is absorbed into the brake fluid and distributed throughout the fluid. So eventually you can get most of the water out, but that would take a long time and countless gallons of fluid.
Think of simple diffusion.

They're actually very manageable with the right tool. They also keep a constant tension on the hose even if the hose shrinks.

I am sure you are correct .

I never have the right tools . Bought 2 new long needle nose pliers for the task . One with " bent " nose & the other with straight nose .

Also used vice-grips and channel locks .

Please tell me , what should I use ? Hopefully , that is available locally ( not have to special order ? ) .

Of course , I hope I will not need them again for a whilr .

But our little red Sonic uses spring clamps , also . :-(

Thanks , :-)

If you feel the brake fluid needs attention, why not do it right and bleed the system? The new fluid will just stay in the M/C and will not find its way down to where it's needed most, downstream.

Yes it is/I don't.

New-to-me used car is an unknown quantity and a potential gotcha. I wait and see if I've made a terrible mistake before I spend any more money on it.

Of course if you never make terrible mistakes, then this tactic won't be relevant, but I have, and do.
