Did you check the hoses going into the heater core or the hard line running on that side of the motor. Even a pin hole will do the trick. if they are original it would be wise to replace all the hoses after 25 yrs.

add a 160 stat if it never freezes where you are or a 180 if it does. The 160 isnt that great for 15 below weather. Never tried CLR? I use distilled water & (insert brain here!) the stuff from Nick at Arizona GN as it cleans out the crud with 1 bottle. Then change the water each year & do it again. The name of the stuff is ???????
Danm I have a 24 bottle case in the shop! Whats it called?? :crazy:

My Brain is Alive!! RMI 25 Do a search on it.
I'm in TO but have a 1-2 8 oz bottles I may sell to help you out.
PM me if interested? $10 each for 1 treatment plus postage.
I've been using this mix over 10 years with a 160* stat in traffic with AC on 100* day I never see more than 178-180. I do have dual fans & stock rad that is Clean!

I only have a couple to spare so please don't PM me looking for some guys.
I hate to say no but I have to with this stuff.
