Linda asks…

What should I get a Chevy Silverado Diesel or Gas?

My dad has a 2007 Silverado 2500 Duramax Diesel.
My question though, i like the Silverado 3500 but dont know which one is better the gas or Diesel one. Which is better, fuel economy wise and which will last longer, keeping it well maintained?

3500 Silverado with Diesel Duramax with Allison transmission or 3500 Silverado with Vortec Engine?

2500admin answers:

The diesel duramax is your best choice for fuel economy, pulling power, and will last much much longer. The initial cost may be higher, but the resale value is also higher. I also believe that maintenance cost is lower for the diesel. As far as fuel costs the diesel will also run on bio fuel and even veggy oils. The diesel can be easily modified for more hp and better fuel economy and can run with added fuels like propane or natural gas injection.
We own an 85k10 turbo diesel an have been driving it for over 14 years, while we have done some upgrading and maintenance to it, its a strong running truck that cheap to keep. Mostlly just oil/filter changes and add diesel and drive it. With syntetic oil we are getting over 22mpg hyw which is good for a full size 4×4 with big agressive off road tires.

Here is a good reference for the duramax diesel

you should do even better with your duramax.

Why don’t you look up all that useless information yourself.

Chevy Silverado 2500 6.6L diesel head gasket replacement?

I have a 2005 Chevy Silverado 2500 6.6L and the head gaskets are bad due to driving on a bad water pump for a couple weeks. I replaced the water pump, and then realized the head gaskets were done. The truck is now at the dealer and they just sent the heads to the machine shop and came back saying they were cracked. It is just hard to believe this is true since the truck wasn’t even overheating. Pressure was building in the coolant system but I’m very easy on the truck when I drive it.

I feel like the dealer is trying to pull a quick one on me. Just curious as to what types of conditions and scenarios usually lead to cracked heads. I could see it if I was hauling a ton of weight up a hill and my truck overheated to the point of it dying on me. But I could barely tell the gaskets were bad so its a little hard to believe the heads were cracked. Any insight here diesel mechanics?

2500admin answers:

Wouldnt take much for an aluminum head to crack. Most likely with a bad water pump, in the case its not flowing, its going to over heat, if It got hot enough to blow both head gaskets I would say they arent lying about the heads being cracked.

Mandy asks…

Towing capacity for 1996 Silverado 2500 6.5l diesel 2wd?

I am looking at buying a 1996 Chevy Silverado 2500 2wd with a 6.5 diesel in it as a pull vehicle for my travel trailer. I have to have approx 10,000 lbs in towing capacity for it. I’m trying to figure out if this is a truck that would be worth it for me.

If nothing else, it would be helpful to find out where I could find a good website that would list towing capacities for vehicles.

Thanks for your help.

2500admin answers:

The capacity is there for the truck, but as with anything to do with towing, it all depends on the hitch.

Get a Class 5 hitch from Reese and you will not have any problems. The truck will pull it just fine. Only difference between the 2500 and 3500 is the rear leaf-springs.

Laura asks…

whats the horsepower on a 2008 silverado 2500 hd running on diesel?

I was just wondering cuse we trying to buy one

2500admin answers:

Horsepower: 365@3200 RPM
Torque: 660@1600 RPM

Hint: Torque is what gives the grunt to pull heavy loads. If you want to actually use the truck as a truck the torque of the diesel engine is what you want.

If you are going to use this truck as a car then consider getting one with the 6.0L gasoline engine. It will be less expensive to purchase and way less expensive to maintain. Yes, a diesel will get you better fuel economy. But they cost lots more money to maintain.

For example the Duramax requires 10 quarts of oil for an oil change, twice as much oil as the gasoline engine. The oil filter costs more also.

With any diesel you must change the fuel filters religiously. If you don’t expect some costly fuel system repairs.

A diesel truck requires 2 heavy duty batteries to start the engine. More costly to replace.

You also have a whole new set of issues if you live in a colder climate.

If you live anyplace where the temperature gets below freezing the fuel in the tank and fuel lines will turn to gel. To fix you need to bring it to a diesel mechanic for some costly repairs. You must religiously add an anti-gel fluid to the fuel during the winter.

Any diesel engine is next to impossible to start in cold weather. Where I live nearly everyone uses an electric engine block heater to keep the engine warm enough to start in the morning.
