2011 Toyota Highlander Engine Oil Cooler Pipe Seepage: What It Really Costs to Fix
Quick answer: 2011 Toyota Highlander engine oil cooler pipe seepage typically costs $250 to $700 at an independent shop, depending on which component failed.
Applies to: 3.5L V6 with towing package. Other versions of the 2011 Toyota Highlander do not have this problem.
What the Issue Is
Toyota's technical service bulletin T-SB-0201-11 covers engine oil seeping from the oil cooler pipe on 3.5-liter V6 engines fitted with the towing package. For the Highlander it lists 2008 to 2011 models and the 2011 Highlander Hybrid; the same bulletin covers 2007 to 2011 Siennas and 2009 to 2011 Venzas. The seep shows up as oily wetness around the cooler pipe low on the front of the engine and can leave drips under the car.
Toyota backed the repair, replacement oil cooler pipes, with a warranty enhancement: coverage with no mileage limit until January 31, 2016, and after that for 10 years or 150,000 miles from the car's first use. Both limits have now passed for every 2008 to 2011 Highlander, so today the repair is paid. It is a modest job by the standard of engine oil leaks.
Do not confuse it with Toyota's separate VVT-i oil line campaign, Limited Service Campaign 90K, which replaced an oil hose with a rubber section. For the Highlander that campaign covered only certain 2008 model-year vehicles, and it ended on December 31, 2021. Neither program covers a 2012 or 2013 Highlander.
Symptoms to Watch For
- 1.Oily wetness around the oil cooler pipe at the front lower engine
- 2.Oil spots under the front of the vehicle after parking
- 3.Oil residue on the engine undercover or lower subframe
- 4.Oil level dropping slowly between changes with no smoke from the exhaust
Real Repair Costs

Mechanic's Tip: Spot It Before You Buy
On the lift during your pre-purchase inspection, have the tech find the engine oil cooler pipes low on the front of the engine and look for fresh oil on and below them. First confirm the car has the towing package, since the bulletin applies only to those. Dry pipes plus dealer records of the bulletin repair means the job is done; wet pipes mean a modest repair to budget, and a reason to check the oil level right there.
The Bigger Ownership Picture
Beyond this specific issue, budget roughly $1,100-$1,600 per year for scheduled maintenance and likely out-of-warranty repairs on a 2011 Toyota Highlander. That is a typical US range from Avturo's ownership-cost table, an estimate rather than a quote, and it excludes insurance, fuel, and financing.

Frequently Asked Questions
Which Highlander years have the oil cooler pipe seep?▼
Toyota's bulletin T-SB-0201-11 covers 2008 to 2011 Highlanders with the 3.5-liter V6 and the towing package, plus the 2011 Highlander Hybrid. A 2012 or 2013 Highlander is outside it. The warranty enhancement that paid for the repair has closed for all of these model years.
How much does the oil cooler pipe fix cost?▼
Replacing the oil cooler pipes runs about $250 to $700 at an independent shop: modest parts and straightforward labor. Because Toyota's warranty enhancement has closed, that cost is now the owner's, though cars repaired under the program will show it in dealer records.
Is this the same as the Toyota VVT-i oil line campaign?▼
No. The VVT-i oil line campaign, Limited Service Campaign 90K, replaced an oil hose with a rubber section, and for the Highlander it covered only certain 2008 vehicles before ending on December 31, 2021. The oil cooler pipe seep in T-SB-0201-11 is a separate, slower leak on towing-package cars with its own warranty enhancement.
What happens if the oil cooler pipe keeps seeping?▼
A seep loses oil slowly, so the risk is an owner who never checks the level and lets it run low. Oil on the undercover also hides other leaks and smells when it gets hot. Fix it when convenient, and check the dipstick at every fill-up until then.
