So I’ve got a 350TBI, with between 5-10k miles on it. I fired it up and brought it to operating temp 2 weeks ago, with 35-40* outside temps, no leaks, ran great. Last week it was single digits for handful of days. Truck sat, never started during those days. I started the truck up New Years day, temps were back in 50’s and within a couple minutes of starting I noticed coolant all around the intake manifold valley on both sides (could have started immediately, i walked away right after starting so not sure when leak started). Hard to pinpoint where its coming from (the area around upper hose was dry, so thats not a culprit), seems all around the intake. The coolant was a 50/50 mix, or at least very close to that. Tried to get a couple pictures, didnt come out very well, but hopefully helps.
Could the exposure to the single digit temps expand (freeze) the coolant and stretch the intake manifold bolts and create a leak even if the truck wasnt run, assuming a reasonable coolant mix? Scratching my head on this.
What do you think? How severe could this be? Surely it couldnt have done something like cracked the block…could it?
