So as most of you know we recently purchased a used 2007 Chevrolet Suburban. Unfortunately, not even a week after we purchased it the check engine light came on; which was then followed by the smell of gas in the passenger compartment.
I was able to use my code reader to read what code it was giving. It turned out to be a code for a vacuum leak in the fuel tank. I’ve learned that this can sometimes mean your gas cap is either defective or not screwed on all the way but, upon further investigation I found a wet spot at the bottom of fuel tank that was about 10-12 in diameter.
I immediately took it to the dealership to see if they knew anything about this particular problem. They ended up giving me a quote to drop the fuel tank for $600 to find out the source of the leak!
I was not willing to give them $600 in labor to just drop the tank! I didn’t have a manual for the suburban yet nor did I think I would need one this soon. I checked out the local auto parts store but they didn’t have my model year in stock.
Luckily after doing a little research on the internet I found that Alldata (a manual that professionals use online) has a do-it-yourself version where you can subscribe to a particular year, make and model vehicle manual. Sometimes your local library may subscribe to Alldata, then you can use it for free. I subscribed for ease of use. I was able to print the entire process which included pictures; and have it with me under the car during the entire process.
Unfortunately, I had just filled up the tank; which meant I had to siphon out all 31 gallons…not fun. I was able to carefully lower the tank to the ground using jack stands, wood blocks and some upper body strength (could be improved : ).
Once on the ground the first thing that caught my eye was a little sensor that was not plugged into it’s hole all the way. The sensor had rubber fins which broke off in some areas; so I made a trip to the parts store again and found a sealant that would stand up to gas. I put the sealant on the sensors fins and plugged it back in.
I was able to get everything done in about 4 hours. I was able the clear the code for the check engine light with my code reader which has not come on since then. Oh yeah! I’m good! : )
FYI, the code readers that plug into your laptop computer are high functioning and don’t cost much. They will save you a bunch of trips to the mechanic or the auto parts store.
What repairs have you made to your car? Anyone tried the windshield chip repair in Sewell, NJ yet?
