Should I Purchase?

Car Information:
Chevy Silverado
Year: 2000
Engine Size: 4.8
Trans: Automatic

Issue/Question:
I am considering buying this truck to tow a 25′ travel trailer, it has the tow pkge. The owner said he bought it new, changed the petro. oil every 3,000 mi. But, it has 260,000 miles on it and he wants $3,500. I have not seen it yet, but he says it runs perfect and the A/C is cold. I WILL change to Amsoil if I buy it. But, what do you think of Silverados? What usually needs repairing. Or should I forget this truck? Is the mileage too high to consider it?

Answer:
We cannot beat up on the truck because of mileage but you must have it checked over before you buy it! Give us a call and we will set a time to do a pre purchase inspection. 407-629-2661

Performance Upgrades

Car Information:
Chevy Silverado Crewcab LT
Year: 2008
Engine Size: 4.8/3.23
Trans: Automatic

Issue / Question:
I purchased this truck new at a great price and it’s all mine. I’m pulling a 4,000 lb 20′ travel trailer a few times a year in the Blue Ridge Mountains. At the price I paid for the truck I can afford to do a few performance upgrades if they would help. I also installed the Rough Country 2″ leveling kit and am considering replacing the 245/70-17 with 285/70-17 but don’t want to hurt the trucks performance. What upgrades are worth the money? Cold air, exhaust system, chip, 3.73 gearing. Truck is currently getting 14-15 in town and 19 – 20 hwy. It has 12k on it and I switched to amsoil at 6K. Can you help me dial in this Chevy’s performance?

Answer:
Unless theirs a computer update available that’s about all that will really help as far as performance and fuel economy. Cold air induction, and duel exhaust may help a little but the extra noise associated with these items are sometimes not worth the trade off and often customers will have us install the original parts back onto the vehicle.

Problems Starting Chevy Silverado

Car Information:
Chevy Silverado
Year: 1998
Engine Size: 350
Trans: Automatic

Issue / Question:
Will not start after sitting overnight, and very humid in am. Have replaced distributor cap, rotor. W/d 40 under cap has no effect, neither does starting fluid.
Runs well when running.
Don’t know if it matters but fuel gauge shimmies back and forth quickly.
Will often start fine after sitting to mid-day

Answer:
Gas gauge may be a giveaway! The sending unit and the electric fuel pump share the same ground at the connector by the fuel tank. Over time this ground becomes overheated due to excessive amps drawn by the fuel pump, intermittent fuel pump and fuel gauge fluctuations are common when this condition occurs and intermittent fuel pump operation can be expected.

Bad Fuel Pump in Chevy Suburban?

Car Information:
Chevy Suburban
Year: 2005
Engine Size: 5.3
Trans: Automatic

Issue / Question:
Starts hard after running a while. Always starts but usually takes 2 turns of the key. Once its running it runs great.

Answer:
It could be a bad one way check valve in the fuel pump. If it sticks and does not seal it will allow fuel to return to the tank when the vehicle isn’t running then when you go to restart you have to crank and chase all the air out of the fuel system and re prime before it will start. When it does this instead of cranking, cycle the key to on then off 4 or 5 times before cranking if it starts right up theirs a 99% chance a new fuel pump will be needed to correct the problem.

Chevy Silverado Instrument Cluster

Car Information:
Chevy Silverado
Year: 2003
Engine Size: 6 cylinder
Trans: Automatic

Issue / Question:
I parked the truck with the engine running. I was transporting an elderly gentleman so I left him with the AC while I loaded the truck. When I got back in the gauges on the instrument panel weren’t working. I could not find a fuse marked gauges so I started pulling fuses and have not found a bad one. All of the lights and LCDs on the cluster work.

Answer:
The Instrument cluster may have failed, I know it sounds crazy but these are famous for this and to make matters worse the entire cluster has to be replaced.

Flushing transmission?

Car Information:
Chevy Silverado
Year: 2004
Engine Size: 4800
Trans: Automatic

Issue / Question:
Am thinking about putting synthetic oil in the transmission. Should I let them flush transmission before they put the new oil in?

Answer:
That’s not necessary and I don’t recommend flushing the transmission, have the pan dropped the filter replaced and top it back off with Amsoil ATF. Flushing disturbs debris and it can get trapped into the valve body and cause shifting problems.

A/C Fan Control Switch

Car Information:
Chevy Silverado
Year: 2001
Engine Size: 5.3
Trans: Automatic

Issue/ Question:
A/C fan control switch does not work in positions 1,2 & 3. Each number position failed systematically over a period of time. Is this a relay problem or a switch problem and where is the relay located?

Answer:
Blower motor resistor is burnt into on position #1, #2, #3 when its on high – voltage is a direct 12 volts and does not travel through the resistor that’s why you still high blower,

The resistor gets extremely hot when positions 1,2,3 are used that’s why they locate it in the evaporator case so the fan actually cools the resistor. In most cases the resistor fails because the blower motor is worn and drawing to many amps, which in turn cause’s the resistor to overheat and burn up. In many cases since its 9 years old we would recommend replacing both the fan motor and resistor, if not theirs a real good chance the resistor will only last a short time.
