1994 Chevrolet Suburban Reviews - Page 2 of 2

I got a mysterious leak in the radiator twice and replaced it twice. The second time I replaced it, I did the work myself and found out why it kept developing a leak. There is a screw that holds the plastic piece above the bumper that is the wrong type of screw. The screw has a pointed tip and goes though the plastic piece on the bumper and into the part of the engine compartment infront of the radiator. It takes 2 to 5 years for the radiator to move forward just enough to jar itself into that screw and create a very small hole in the tank on the driver side.

I fixed it by screwing the screw half way out.

I have pictures if anyone wants to see them.

Radiator leak cased by a screw that is pointed instead of flat and the screw is too long.

The leak happens only on the driver side because the passenger side screw is beyond the width of the radiator.

A sealant will seal the tiny hole for about a week.

I have pictures.

Drive shaft has corroded. I had it replaced with a steel one at a drive shaft shop; never could get it balanced properly. I should have got the $700 GM one.

No other problems.

I have loved my suburbans. This one only gets 17 mpg where the 1985 Diesel got 20-25mpg highway, but it is nice to be able to start it when it is -10F.

I have had to replace the fuel filter.

The timing belt needed to be replaced.

Other than that, just normal maintence; oil, air-filter, and tires.

With over 140,000 miles, the 454 still beats anything out there. Even in a 3-ton truck, I eat many upgraded cars off the line.

I am the second owner; the previous owner took very good care of her. I have had to do nothing, and with a soon better exhaust and K&N air-filter kit, this engine will scream.

I have the 2500 Heavy Duty so mine has skids plates and a better transfer case. I have had this beast air-born many times and she still drives like she was right off the assembly line.

Put 700 pounds in the back and she will ride like a Caddy.

You can beat these trucks to death and they will keep coming back.

Treat them like an angle, and you couldn't stop them with a 3 pound sledge and a bad attitude.
