Silicate drop out. Ethylene or Propylene Glycol has a two year shelf life from the date of manufacture. There is a date code on the bottle. When the coolant is spent, it degrades and the corrosion inhibitors can contribute to
cooling problems by plugging cores and preventing heat transfer.
OAT and Hoat have a 5 year shelf life, I haven't seen any issues with them yet and cooling systems look pretty darn clean.
I got to learn a lot about coolant when I bought my 6.0 Powerstroke. That thing has an oil cooler in the valley that is susceptible to plugging and creating a whole slew of problems. I've been switching everything to CAT EC-1 coolant including the jeep.
Just ordered a Mishimoto, going to compare it to my 5+ year old Griffin direct fit. It appears to have about 24% more cooling area just based on tube count/size.
Griffin has 23 rows of 1.5" tube (38.1mm) while the Mishi has 26 rows of dual 22mm. Also ordered a Trinity fan controller from Nick.
