bearing silicone rubber oil seals

Bearing silicone rubber oil seals.Before starting all these repairs I removed the plastic splash guard that extends from the front bumper to the front axle area. There were 6 bolts to take out.
After I put the car back together, I installed the oil filter, replaced the oil drain plug, and put the usual 4-1/2 quarts of oil in the engine. Then I ran the engine and checked for leaks.
When I checked the oil level, it was about 1/2 quart low. That didn't surprise me, given how much oil spilled out of the oil cooler lines. That also explains why whenever I've changed the oil in this car, the oil looks dirty right away. There is a half-quart of old oil in the oil cooler lines that doesn't drain out. Next time I change the oil I think I'll try blowing compressed air into the oil filter center connection. Maybe it will purge the oil cooler lines. I'll let y'all know.Bearing silicone rubber oil seals.
Some GMC Jimmys and Chevy Blazers have an engine oil cooler.  When a mechanic is asked to fix an oil leak, he (or she) will normally degrease the engine first. Finding the source of an oil leak is much easier wihen the engine is clean.
But the oil wasn't leaking from the engine. There was a large wet oily spot just behind the radiator, on the driver's side.
I did this repair while I had the car in my garage to replace the water pump. This task was easier with the radiator fan and fan shroud removed, but it should be possible with those things left in place.Bearing silicone rubber oil seals.
Properly disposing of used solvent isn't simple. Similar to a transmission fluid cooler, the oil cooler is actually placed inside the radiator, with metal/rubber lines that carry the pressurized engine oil to and from the oil filter. Furthermore, the Blazer/Jimmy has a remote oil filter. I guess GM did this because the 4.3 liter V6 engine fits so tight there was no room for an oil filter mounted to the engine block.Bearing silicone rubber oil seals.
The 1999 Jimmy in this article had been leaking oil for several years.I just pour the mineral spirits back into an empty paint thinner jug and label it as "used". In my area, the county runs a hazardous waste disposal program where homeowners can drop off stuff like used paint thinner. Also, if I'm having a bonfire, I'll pour a little used paint thinner on the firewood before igniting it. After all, this is basically barbeque starter.
