Mark, This is probably a better question for Bob but here is my two cents worth from the corner.
The only way that you can drain that system is by removing the lower radiator hose and stand by for the inevitable shower. There should be some kind of a filler type cap or fitting on the top of the radiator core however it will in no way resemble the RAD caps we are used to. Now instead of having a traditional upper tank and pressure cap on the radiator there is an expansion or overflow tank. When an engine overheats the coolant is forced up a hose into this tank rather than running out on the ground. Finally there should be a fitting on top of the thermostat housing to purge the air. Honestly my friend I would probably take it to a trusted technician because now days you can get hung for not disposing of coolant in the government approved manner. Secondly pulling the hose doesn't always get all of the old coolant out of the motor and finally if you don't get all of the air out of the system it can create an air-lock that could cost you a motor. The current state of the industry is to suction the old coolant out of the system, replace the thermostat and refill with fresh coolant. I have done this job using the lower hose and bucket routine but it is no fun and I do not recommend it. -----Original Message----- From: blindhandyman@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of mark Sent: Thursday, November 20, 2008 10:56 AM To: blindhandyman@yahoogroups.com Subject: [BlindHandyMan] drainingg and refilling antifreeze hey gang got a 2002 chevy venture van and need to change the antifreeze did not find a petcot valve to drain the antifreeze that is in the system can anyone shed some light where this is located and seems like the radiator cap is not on top of the radiator so how do i refill with the fressh antifreeze the next thing is where is the bleeder valves located to purge the air out of this thing thanks alot any help would be great it is getting alittle cold up here in n. e. pa. and do not want to freeze the block thanks again [Non-text portions of this message have been removed] ------------------------------------ Send any questions regarding list management to: [EMAIL PROTECTED] To listen to the show archives go to link http://www.acbradio.org/pweb/index.php?module=pagemaster&PAGE_user_op=view_p age&PAGE_id=33&MMN_position=47:29 Or ftp://ftp.acbradio.org/acbradio-archives/handyman/ The Pod Cast address for the Blind Handy Man Show is. http://www.acbradio.org/news/xml/podcast.php?pgm=saturday Visit The Blind Handy Man Files Page To Review Contributions From Various List Members At The Following address: http://www.jaws-users.com/JAWS/handyman/ Visit the archives page at the following address http://www.mail-archive.com/blindhandyman@yahoogroups.com/ If you would like to join the JAWS Users List, then visit the following address for more information: http://www.jaws-users.com/ For a complete list of email commands pertaining to the Blind Handy Man list just send a blank message to: [EMAIL PROTECTED] Groups Links -- BEGIN-ANTISPAM-VOTING-LINKS ------------------------------------------------------ Teach InfoWest Spam Trap if this mail (ID 224297152) is spam: Spam: https://spamtrap.infowest.com/canit/b.php?i=224297152&m=b7720a5a459c&c=s Not spam: https://spamtrap.infowest.com/canit/b.php?i=224297152&m=b7720a5a459c&c=n Forget vote: https://spamtrap.infowest.com/canit/b.php?i=224297152&m=b7720a5a459c&c=f REMEMBER: Never give out your account information, password, or other personal information over e-mail. ------------------------------------------------------ END-ANTISPAM-VOTING-LINKS
