My truck was built in Feb 03. I just replaced the coolant, t-stat, upper/lower hoses 3 weeks ago. Truck has 76k on it.How often are you guys flushing your cooling systems and replacing antifreeze?
Motorcraft Gold is Zerex G-05Is the Zerex coolant some good stuff?I see both replies have used it so far.I was going to use the Motorcraft Gold, but if this stuff is better than I'll go w/ it instead.
No, you really don't. I did it cause it was 5+ years old & thought as long as I was doing coolant, I may as well do hoses and t-stat too. I probably didn't need to after looking at what I took off.Do you need to remove the thermostat to flush?
