Hey, all.
I have a bunch of small coolant leaks on the ’92 Ranger (4.0, A4LD) that I picked up a month ago. I plan to take pics for the more detailed ones later, but to start with, I noticed that the bottom of the cap on the coolant overflow/fill reservoir is soaking wet with coolant after a drive. I read somewhere that it’s not a pressurized reservoir, but shouldn’t there still be some kind of an o-ring or something on the cap where it presses down onto the tank neck? If not and if I’m getting this kind of leak, does it mean that there’s excessive pressure in the system somewhere? My heat works great by the way, so the core shouldn’t be plugged.
Also, is there a safe flushing agent out there for the coolant system? I’m in the process of changing every fluid in the truck and am just wondering if there’s a good product out there, or if I’ll just be using gallons of straight distilled water like I usually do to flush things (I use this instead of tap water, since it contains less minerals). Thanks!
