Buick Super Engine Oil Cooler Mounting Kits

Buick Super Engine oil cooler mounting kits

Starting at $20.95, AutoBuffy stocks 1 engine oil cooler mounting kits from Four Seasons. This kit provides the gaskets, bolts, O-rings, and brackets that seal and secure the oil cooler to the engine block or adapter plate. When these components fail, oil and coolant can mix or leak externally, leading to rapid engine damage if left unaddressed.

Signs your Buick Super needs a new engine oil cooler mounting kit

  • Milky or frothy oil on the dipstick or under the oil filler cap, indicating coolant contamination
  • Oily residue or discoloration visible in the coolant reservoir or radiator overflow tank
  • Visible oil seeping from the base of the oil cooler or around the adapter plate mounting surface
  • Unexplained coolant loss with no external radiator or hose leak present
  • Oil pressure warning light triggered by loss of oil volume through a failing cooler seal
  • Overheating under load caused by restricted coolant flow when a collapsed O-ring blocks the cooler passage

Which engine oil cooler mounting kit should you buy for your Buick Super?

The most important decision is whether the kit matches your specific cooler configuration — sandwich-plate style, block-mounted, or integrated adapter. Kits vary in what they include: some cover only O-rings and gaskets, while full kits add mounting hardware, brackets, and thread sealant. Choosing a complete kit up front avoids mid-job hardware runs.

Replacing an engine oil cooler mounting kit on a Buick Super

Moderate⏱ 1–3 hoursSocket and ratchet setTorque wrenchOil drain panPick or O-ring removal toolThread cleaning brush or tap set

Begin by draining the oil and coolant to prevent spills, then unbolt the oil cooler from its mounting surface and carefully remove all old O-rings, gaskets, and corroded hardware. Clean the mating surfaces thoroughly before installing new seals from the kit, as any debris or surface damage will cause an immediate re-leak. Reinstall the cooler with new hardware to the manufacturer's general tightening sequence, refill fluids, and run the engine to check for leaks before returning the vehicle to service.

Frequently asked questions

How much does it cost to replace engine oil cooler mounting kits on a Buick Super?
Parts start at $20.95 for a Buick Super engine oil cooler mounting kit at AutoBuffy. Professional labor typically adds one to three hours of shop time depending on cooler location and accessibility. Catching a failed mounting kit early is far less expensive than repairing an engine damaged by oil-coolant cross-contamination.
Can I drive my Buick Super with a leaking oil cooler mounting kit?
You should not drive with a leaking oil cooler mounting kit. Even a small breach can allow coolant into the oil, stripping lubrication from bearings and journals within a short drive. If you see milky oil or an active external leak, stop driving and inspect the cooler mounting immediately to prevent serious engine damage.
How long do engine oil cooler mounting kits last on a Buick Super?
Most O-rings and gaskets in an oil cooler mounting kit last many years under normal conditions, but heat cycling, coolant acidity, and age cause rubber seals to harden and crack over time. High-mileage engines, frequent towing, or extended overheating events will shorten seal life considerably. Inspect the cooler seals whenever the oil cooler itself is removed.
Will any oil cooler mounting kit fit my Buick Super, or does it have to be vehicle-specific?
The kit must match your specific cooler design and engine block port layout. O-ring diameters, bolt thread pitch, and gasket profile vary across engines, even within the same manufacturer. Always verify fitment using your Buick Super's year, engine code, and cooler type before ordering to ensure proper sealing and secure mounting.
Should I replace the oil cooler itself when I replace the mounting kit on a Buick Super?
If the cooler failed due to internal corrosion, a cracked core, or severely restricted passages, replace both the cooler and the mounting kit together. If the cooler body is structurally sound and the leak was isolated to the seals or fasteners, a new mounting kit alone is sufficient. Inspect the cooler core for damage before deciding.
What happens if coolant and oil mix in my Buick Super's engine?
When coolant enters the oil circuit, it destroys the oil's lubricating film, causing accelerated wear on bearings, camshafts, and cylinder walls. The resulting sludge can also clog oil passages and the oil pickup screen. Continued operation can lead to spun bearings or complete engine failure, making a failed mounting kit seal a high-priority repair.
