Hello everyone.
This site has been very helpful and I thank everyone for their insight.
Oh and the Birf DVD is simply great!
so here is the story....
I have a 97 lx450 with 120k. I have owned since 72k. I have developed rust in the radiator. Seems like it has gotten worse since the PHH blew last year. (laugh/moan here). Anyway I have done 3 rad flushes since then and the rust just keeps coming up and depositing on the top of the rad cap and the overflow tank. I know I am opening up a big plug for not doing the flush correctly, but really i have been flushing pretty good. (hey, I even flushed through the phh once!) I have been draining the block and the rad, filling via prestone tee, running engine, flushing, draining, refilling, etc, till I have hot clear water coming out everywhere - block, rad top, rad petcock. My current plan is to just keep cleaning the rad cap (the rust is like a sticky residue) and cleaning out the overflow resevoir. I am also considering putting in a dreaded radiator cleaning additive. I understand this is not recommended by most, but I want to get this rust out. I know someone may advise pro cleaning - anybody know how much they charge for professional cleaning. Any and all advice and/or wisecracks are appreciated....
thanks, Troy in Oregon
