hey guys. I'm trying tofind the coolant drain. The manual has a crapy drawing. I've drained most of the coolant from the lower hose, but would liketo find that drain.

Also, any sites with detailed coolant flush instructs?

Thanks, Bennett

It's a little plug on the side of the engine, at the bottom of the center housing, below the oil filler/dipstick. It can be hard to spot on cars with air oil coolers, but you should be able to see it OK.

Its also normally covered in grease and gook like the whole underside of your engine... so look carefully.

If I recall correctly its a 14mm bolt

Yes, it is 14mm and is at the lowest point on the intermediate housing below the oil filler tube and dipstick. It is right above the oil pan (yes, it's real low and covered with oily dirt). The oil cooler hose is really close to it, so you might have pretty good luck using a box wrench (but I do prefere the rachet because it's quicker).

i was told that the best way to clean the radiator is to take it out and flush it with degreaser.i used the purple stuff.flushing your system with that radiator flush running through a rotary motor is real bad for the seals.my mechanic said never use it.i take my radiator out once a year.looks as clean as the first time i did it.going 3 years on rebuild 35,000 + miles.

Once you drain it make sure to use distilled water with your antifreeze. It will protect your engine better and will lower your temp a few degrees.

I only use a tad of antifreeze in the summer. I flush the system in the spring and summer. 20/80 Anti-freeze to water in the spring and 50/50 in the fall. And ALWAYS used distilled water. I get mine from my de-humidifier in the basement.

I found the drain after some digging and scraping. I'll put a pic for reference if I ever find my camera. Anyone draining should note that the coolant drain is smaller than the main oil drain (about 13/16" or something) ! Trial and error on my part

Thanks-- Bennett

Inches? Inches?!? INCHES!!! What are you doing using SAE tools on a Japaneese car for!?! Are you nuts?!? (Just playin with ya. )

Serzy

Invest in a set of 8-17mm wrenchs & sockets, metric is soooooo easy and there shouldnt be ANY SAE sizes on your car....

Got a 90 Piece set of Crastsman sockets and combo wrenches last Christmas. Good set and life time warranty.

"Okay.. See how this mangled blob of metal says "Ftsman"??? Yeah. It used to be a 1/2 inch drive ratchet... What ahppened to it? Oh.. Thats a L-O-N-G story."

bennett

Yeah I know you guys are right but the nut was misshapen somehow (probaly from someone using a 13/16" ) anyway, the metric size wouldn't fit. I love working in metric.

13/16"? isn't that close to an inch? Ah, I've been working with metric for a long time

Isn't 14mm close to 9/16" or something? At any rate, go ahead and loosen the plug and see what comes out. If it's oil, you did the wrong one hehe.
