I have an ‘02 GMC Sonoma 4.3 crew cab 4×4. While stopped, idling and in park, the fuel gauge needle will start to fluctuate. Then it will suddenly drop to empty. It may come back up slowly while driving or all at once. I had false readings before but this didn’t start until I used Techron fuel system cleaner. Any ideas?
I have some questions about R-134 air conditioning systems. With the high temperatures of south Texas this summer, the low side pressure has been increased by about 5psi in the heat of the day on various vehicles. Is the increase in pressure caused by air in the system expanding and being pushed through the system by the compressor? This is resulting in air conditioning not being as cold because of the pressure build. If this is the case, what is the best way to bleed the air out of the system?
I have an ’07 Mustang V6 with about 40,000 miles and I’m using 5-30 synthetic oil. At what mileage do I upgrade to a higher weight?
Many Ford vehicles along with others recommend the use of 5w30 motor oil. On some Ford vehicles, using a higher-viscosity oil can set a DTC (Diagnostic Trouble Code) which is related to the use of wrong oil, contaminated oils, or using the wrong oil filter. Keep your vehicle maintained and use the correct weight, there
Probably the biggest reason is there are corrosion-inhibiting additives in antifreeze that protect the cooling system against rust and electrolysis. Those additives get eaten up over time, requiring the antifreeze to be changed periodically. Mark Phillips Editor Counterman magazine
I recently just purchased a Chevrolet with over 150,000 miles on it. Is it possible for it to last as long as a Toyota or a Nissan, and what can I do to help it last that long?
A key factor in having any vehicle perform at its optimum peak can be summed up in two words, PROPER MAINTENANCE. This means changing oils, filters and other components at regular intervals that are suggested by the vehicle manufacturer. I have had vehicles that I have properly maintained, and have gotten more than 200,000 miles
I’ve had many customers asked me if the fuel filter had to be changed when doing a tune-up on a 95-08 Dodge pickup. Is it part of the fuel pump assembly and can it be serviced?
If your Dodge pickup has a gasoline engine, you have a non-serviceable fuel filter. If problems arise with the pump the filter should be changed at that time. Jerry Ives Assistant Professor, Parts Technology Alfred State College, Wellsville Campus www.alfredstate.edu
I had a customer ask for “semi-chrome” polish. Anybody know if this stuff still exists and where to buy? It’s been a long time since I’ve seen it around.
Good Stuff, works well. Check here for Simichrome. — Craig Bradley NAPA, Lansing, Mich. 2008 Counterman Counter Professional of the Year
