FEL-PRO 35595 Thermostat Gasket

This works if you're in a bind but they don't fit a mercury 3 or 4.3 liter motor. The gasket is too small. It does seal if you modify it but I'd look for the bigger one.

Fit 97 lesabre

Looks well made, but doesn't fit my Buick 3.8, judging by the other reviews, this may be correct for the series 2 3800 (1995-2005), but not for my series 1.

Easy install and great product

It shows correct for application, but it’s definitely incorrect

Made well, seems like it will last a long time

I bought this Fel-Pro 35595 for my 95 Buick Regal with 3.8 (231) engine because Amazon listed as correct fit for my application. It is not correct as others have pointed out. This gasket has the bolt holes on the centerline of the thermostat and too widely spaced. It will not bolt up. The water neck on my manifold has both bolt holes slightly offset in the same direction from the thermostat centerline and more closely spaced. The correct gasket is the Fel-Pro 35534 which has the bolt holes correctly offset and correctly spaced. I found the 35534 gasket at my local parts store for $1.99. I was able rig this gasket well enough to get to the parts store by trimming off the "ears" and carefully centering the now round gasket while I gradually tightened down the bolts. F.Y.I. Amazon also sells the correct Fel-Pro 35534 gasket and you can see the difference in bolt to centerline dimensions in the picture of it. It is also listed as fitting my vehicle/engine. Why such a detailed review of a part that only cost a couple bucks? Because a 20 minute job turned into a 2 hour job and I hope to help others avoid this situation.

Fit my L36 2002 Buick Lesabre like OEM. Fel-Pro has stayed consistent in their quality thru the years and I appreciate that. I rarely ever return a Fel-Pro product. I can’t say that about most companies. Will buy again.

Bought it as a replacement for the one I bought earlier. My first one split. Either from tightening down to much or a defect. I use a gasket sealer when I install this. If it still leaks, you may need a new thermostat housing cover and/or bolts for the housing.

Even though "amazonconfirmedfit" said this would fit my engine, it was NOT the right part. It will be returned.
