Is coolant flush really necessary at 30K?

is it dirty? might as well do it yourself, no point paying a shop 100 bucks, it's really simple

That is exactly what I have in mind.
I am doing searches on the forum about spark plug and auto-tran fluid too.
Trying to see if I can do the plugs and the auto-tran fluid replacement myself.
The plugs sound easy enough but I don't know about the auto-tran fluid.
 
It only will cost me $40 for a coolant flush.

I thought you had to change the green coolant every 2 years or 25K miles
 
Ok...I've had a Ranger, an Eclipse and a CR-V prior to my two P5s.

All bought new, and all w/80,xxx+ miles when I sold or traded them in. I never did a damned thing to any of them other than replace brakes on the Ranger, replace the tires on all, and change the oil.

My father has had cars w/150,xxx + as well and has never even changed out a timing belt. Never has a one of our vehicles broken down (well, except for a '69 Ford pickup back in the '80's).

What am I missing with all these big ticket routine maintenance visits to the dealership?

don't count on it. Plus its called preventive maintainance.

To answer the question though, I change my coolant every other summer. Its doesn't cost much to do it, plus if you are incline enough, you probably can do it yourself, its so bloody easy.
 
:( Went to 2 Schucks stores nearby and no luck getting any NGK plugs.
Going need to go to AutoZone a couple exits further.
Well, I am going to do my oil change first now.
 
I wouldn't do an automatic tranny flush myself but that's just me. I did my manual tranny and coolant at 31k miles. just remember to get the car hot before drainging the coolant or else the thermostat wont be open and you wont get the coolant that is in the engine block. then fill it back up slowly and be sur to get rid of all the air bubbles.

Plugs are easy:
1) Unplug the wires and pull them out.
2) Unplug, unbolt and pull the coil packs
3) Get yourself a spark plug socket and go to town on 'em
4) When putting the new ones in, be very careful not to overtighten. Hand tight, and then maybe a litle bit more (quarter turn?)
5) Reassemble everything.
6) Turn key
7) Zoom zoom
 
Dude its so simple... theres a how to on the tranny flush. Turning it on is a good i dea if you want to "flush it" but not for very long.

Coolant flush is just that little plastic screw on the bottom of your radiator. Then put the screw slightly back in and run distlled water through it so that it still drop a little but it will also let the whole radiator fill up. Then pull screw out to drain water... do your mixture and pour it in and your done. Drive it for a lil bit and when you get youll prob need to add more fluid.

NO.
No no no.

Everything you said is correct, the water must be distilled, the plug is on the bottom, but the car MUST be hot. Not "sort of" warmed up, but at normal operating temperatire. As someone else mentioned, the thermo must be open.

Also, as it drains, with the thermo open, squeeze all the pipes. This will (temporarily) suck in air and force the last bit of coolant out. Pour at least 2 gallons of distilled water through the system, and start the engine for a couple minutes after the first gallon to push the clean water through the system. Stop it, pour the 2nd gallon, and then. close, fill, run, and top off as needed.

I've done it myself only to learn the procedure for the car. Doing a flush with pressurized water is miles better, and as noted only costs about $40-50 bucks.
 
The first comment was for the tranny flush not the coolant flush. yes the engine most have just come from a drive
