Default Re: How To Replace Thermostat 2.5L (1999)

^^^ good stuff! & be careful when removing the cap if the system is still under pressure.

yeah, after your truck gets up to temp, the gas bubbles will expand. then when you shut it off and let it cool down, the bubbles will shrink back down and suck in fluid from the reservoir. be sure and check the res fluid level for a few days afterwards

and that's nice to hear you & your son had a good time! that sounds like me & my dad when we dig into a project lol
