If you tow or plow snow with it, yes.
Yes it is in the radiator.
Where is it leaking from? Oil pan, intake, valve covers, oil cooler lines? welding
the lines are call oil cooler lines
Look and see if you find one. I just replaced the o-rings and gaskets on my 93 S10 Blazer 4WD, there is a block where the oil filter would normally go and hoses leading up to the remote oil filter location under the air filter housing, the oil filter housing has a cover on the opposite side of the hoses marked oil cooler where an oil cooler hose set would lead to an oil cooler if it had one. I suspect your blazer is like mine and doesn't have an oil cooler. The kit I had to get with the gaskets and o-rings was called an oil cooler repair kit. I have the 4.3 v6 with the cci vortec injection. I was wrong in telling you that my 93 S10 Blazer didn't have an oil cooler, I looked at it again today to help answer another question and found oil cooler lines leading from the remote oil filter housing. They go down which is why I didn't see them when I worked on the lines from the engine. there should be two oil lines running from above the oil filter to the rad, just like an a/t cooling line
The 3 top areas on this model are: valve cover gaskets, oil sending unit,oil cooler lines.
Yes you do.
You may need to replace your oil pump.
Need to know what year S10 and what engine size to tell you how many quarts of engine oil it takes.
oil cooler is located on lower right side of engine need to get under vehicle to see it
It is built into the radiator side tank, Just follow the 2 oil lines that are just above the oil filter adaptor and you will see that they run up the side of the engine and go into the radiator on driver's side. Must replace radiator to fix oil cooler.
To change the oil in a Chevrolet S10, you need to unscrew the old oil filter, drain the oil, screw the new oil filter in and replace drain plug, then add new oil. Please dispose if old oil and filters appropriately.
Yes
