#19 of 45 what about... by jgmilberg Oct 06, 2001 (12:47 am)
I remember seeing a radiator cap with a sacrificial anode attached with a brass chain. It was supposed to keep the acid from attacking the radiator core. I don't know if it was a gimmick or not. I never used one. I can't find anything about them on the net, but I know I saw them before.
#20 of 45 Sacrifical anode by q45man Oct 06, 2001 (8:24 am)
Q45 have a special pipe [rad, rubber hose, Anode PIPE bolted to block, rubber hose, engine block] designed to corrode under stress [acidic coolant]. If the PH never gets below 7.0 [neutral] electrodynamic corrosion doesn't occur in water [except sea water high salt]. Simple to test with VOM for parasitic voltage generation ....one lead on aluminum rad, one lead in solution middle of filler neck any voltage measured a no no! nothing above 10-20 millivolts.
#21 of 45 my antifreeze/coolant is by sdayalani Oct 17, 2001 (4:33 pm)
due for a change. is it ok to use the extended life antifreeze on a 99 mazda protege 1.8L instead of the regular one?   the extended life af/c conforms to GM's DEXCOOL specs. i was wondering if i could use it in my protege without any adverse effects. (i dont plan to go 5 yrs/250K miles though). i like the fact that it extends water pump life and its not much costlier than the normal af/c.   has anyone ever done this before? tks
#22 of 45 coolant by joe3891 Oct 19, 2001 (3:37 pm)
I would look in the owners manual and use what the manufacture recommends.
#23 of 45 that orange crud by swschrad Oct 21, 2001 (12:21 pm)
there have been a number of posts as well about DexCool turning into DexCementBlocks in a number of GMs. nobody has any real answers on how to stop it. nothing like a big chunk of solid orange crud to say, "your lifetime coolant is done, because your car's lifetime is over."   I don't trust "lifetime" anything. that's another way of somebody else telling you to shut up and roll over, you're dead when I tell you.

mazda recommends an ethylene glycol-based coolant. now the extended life af/c by havoline (yes, the orange stuff) is also ethylene glycol-based.   i just dont know whether the absence of borates/nitrates etc would have an adverse effect on my car's cooling system.   nevertheless, irrespective of what coolant i use, i plan to change it every 30 months/48,000km as per mfr recommendations

What would be the best coolant to use for a Honda. I have two that need their coolant changed. I have heard the Honda mechanics say that Honda brand should be used (it looks absolutely brand new even after 4-5 years), and would buy that except the nearest dealer is about 200 miles away. Would regular old Prestone be just as good?
