Yes it is in the radiator.
If you tow or plow snow with it, yes.
1989 Chevy s10
Where is it leaking from? Oil pan, intake, valve covers, oil cooler lines? welding
If it had a remote oil cooler, yes. If not, no.
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.
no there is not,if its automatic than its the trans cooler
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.
Is it low on tranny oil, or you might have a bad oil cooler, or is your engine running very hot.
Yes.
It depens on the size of the oil cooler.
