Cadillac CTS Fuel Leak: CTS Floor Cut Specs

Where I cut the floor to access the Fuel Pump

[@danroberts2226]

Thanks so much for the how-to, very good. I used J-B Weld's Marine Weld as it is petroleum resistant. Mine cracked at the same place as yours. One thing I did different was cut three sides with tin snips and then folded the piece back down and secured with several layers of refrigeration tape. Turned out good.

Thank you SO much for posting this video!

Great job on the repair, explanation, measuring and thank you for posting. I'm at repair #2 and out of money for this mess. It's time to DIY so can use my car...2009 CTS-V with another gas leak 141k mileage. first repair was 90k to 100k. Disappointing

Great vid. Thanks so much for taking the time to post and being so patient with it all. Super helpful. Especially for us guys who need to save a couple of bucks. Thanks again.

U should make more fiber glass covers and sell them that would be awesome thank you for the vid. Get back to us

[@tamle9314]

Thanks for the video. I did the same for my 2009 Cadillac cts4 . All measurements are good. However, if I have to do this again I would move the reference point 1" left of the seam. Since the tank is pushed up against the floor on the right, it is very likely that you will cut into the tank. I used a handheld grinder with a metal cutting blade for this. Remember to keep your blade no more than 1/8" thru the floor.

[@omegatotal]

better to get a good sheet metal nibbler, using a drill bit with a piece of rubber hose to limit your penetration, then the nibbler to remove the metal. no sparks or heat with this method, but slightly slower cutting and more kerf.

[@jenbry97]

Second this - move lower left corner 1" further to left.

[@CampbellSuperKids]

I think my car is leaking fuel as well. I can smell it and I also see something leaking along side the fuel tank. Good video thank you

[@MindRightLifeRight]

Saved $1560 doing exactly what you did. No more leaks.

[@danielbollett4476]

repost- How did you make the fiberglass panel ??????? You replied you were going to post a video for the making of the fiber panel do you have a link for that video ??

[@SoCal_Jerry]

The take away is why the heck didn’t Cadillac put this access panel in the original design? Huge mistake as the “right way” to do this is to drop the driveshaft and complete rear end. That’s what my Cadillac Dealership is doing right now on my 2010 CTS. Thousands of $$$ in labor and a tough job! Crazy!!

[@alantorchia6674]

How do you make the fiberglass cover?!

[@agmedia6840]

So this video worked for me and I appreciate it but has anybody put the metal back down and smell gas ? My car smells like gas every time I turn on now after doing this , my questions is what solutions has anyone done too get rid of the smell ? I was thinking of doing aluminum tape or some sound detonating Matt

What year is this CTS? I have a knocking in my gas tank. Going to replace the filter and the pump. Was going to change the pump this way. If you mentioned it in the vid I missed it sorry.

[@thejr3garage910]

maTiCuSdaGum mY You know what I may not have mentioned year. It's a 2008.

[@alejandroproa2626]

Where’s the filter

Daniel Bollett I'll try and get the video up this weekend.

[@hillaryhudson5917]

Did you have to take the back seat out to get to there?

[@thejr3garage910]

Yes, just the bottom seat

[@pkalldayeveryday8354]

Is there any vids out there of someone just doing it the proper way and dropping the tank ? Idk if I want a hole in my floor above a Stanky gas tank specially if they bin known yo leak and smell

[@jbone1383]

kzbin.info/www/bejne/pIHalH-lm7yXb5I you have to remove the whole exhaust, driveshaft AND lower the rear subframe just to drop the tank, it's a huge pita!

[@bryanburns6062]

When you cut? Did it spark while cutting?

[@thejr3garage910]

I believe I drilled a starter hole then used tin snips. The tank is very close to the floor. If you use a cutoff wheel be very careful.

[@omegatotal]

you can also use a sheet metal nibbler, no heat or sparks with that either

[@b747skyguy]

Why not use a Rotozip Spiral Saw, instead of tin snips? Cleaner cut and much faster.

[@thejr3garage910]

Probably because I used what tools I had at the time.

[@blk95gsrt]

Power tools shoot sparks. Sparks and fuel = bad

[@digitalsavage5500]

What years is this CTS??????

[@thejr3garage910]

2008

[@blk95gsrt]

You didn't put what year it is or how far to measure from the side. We can tell how high to go but have no idea how far left or right to go in the car

[@blk95gsrt]

I can see it's by the seat belt, but can't tell if it's driver or passenger side.....

[@thejr3garage910]

2008 cts. @ about 53 seconds I show the seam overlap that I used to measure from. Rear passenger side

[@blk95gsrt]

@@thejr3garage910 Exactly my point. You show the measurement width and depth wise approx 6 x 9, and where to measure from for depth front to back to center the hole. But where do you measure over from the side of the car from? How far? I can cut the size you have and get it right front to back, but from left to right I could easily be off a couple of inches.

[@blk95gsrt]

oh and thank you for the video and the info. and if I missed the info on where to measure from for the left to right centering let me know.

[@thejr3garage910]

@@blk95gsrt the seam is what I used as my start point. On my 2008 CTS, the seam has an overlap. That is my starting point.
