So I took my Blazer ice fishing in northern Ontario, had a blast, caught/ate a bunch of trout etc etc. good times, until it was time to go and i found the block frozen solid, would not even come close to turning over. Block heater is not much use where there's no power I guess, heh. So a little rolling around in the snow and fun with a propane torch (which itself needed to be heated to flow) and i was able to get it started and drive it 5 hours home with no issues. This morning however when i started it there was a clicking that varied in frequency with rpms until the coolant got up to about 70C (guessing maybe some ice in there still). Oil pressure reading on the dash is weird now as well, it climbs quickly to 3/4 on the gauge (i have no idea what number that represents as the gauge is kpa) by 2k rpm. Before being frozen it was pretty much straight up all the time. I'm thinking my coolant mix was not up to par for the temps and froze, and also that i have some gaskets to replace if coolant in the oil is what caused it to thicken/freeze. Other than replacing the LIM gasket and changing the oil and coolant what else should i be checking for after a solid freeze?

 

3/4 of the way is 60 psi or so. My blazer is there all the time when I cold start it, after operating temp is reached it drops to about 20 psi. Pop the rad cap and check your coolant with a tester to find the temps it is good till.
