GMC 1500 Pickup Problems

Miscellaneous -- Verified

The inside and outside door handles are prone to breaking.

Engine -- Verified

The intake manifold gasket may develop and external engine oil or coolant leak. In some cases, an internal coolant leak may occur causing coolant to mix with the engine oil. Running the engine with a coolant/oil mix may result in engine damage. Replacing the intake manifold gasket should correct this issue.

Electrical & Lights -- Verified

The windshield wipers may not work intermittently due to a faulty wiper motor control board. Our technicians tell us that lightly taping on the wiper motor when the fault occurs should temporarily get the wipers working again. Some vehicles were recalled for this problem and some were not. You will need to check with your local dealer to find out if a specific vehicle was included.

Engine -- Verified

The fuel pump may fail causing the engine to stall and not restart. Our technicians recommend replacing the fuel filter every 30,000 miles to help prevent undue strain on the fuel pump.

Heating & Air Conditioning -- Verified

The quick-connect fittings for the heater hoses tend to leak engine coolant. This problem commonly occurs because the metal housing has become brittle, which can break and cause leaks.

GMC 1500 Pickup Reviews

1995 GMC 1500 5.0L. 280K and still running strong. Had to replace intake gaskets twice, heater hose connectors and fuel pump. Only run 20w50 Castrol with Lucas oil stabilizer. I believe that is the secrete to a strong running 305.

I need to change the A/C unity to 134a refrigerant in 92 GMC pickup truck tell me how would I do this and thank you very much

My husband bought this extended cab for me brand new in 1995. I have since put over 470,000 miles on it with only the normal minor repairs. Still looks good on the outside and runs and rides great. The seats are a little ratty looking, but I still love driving it!

Bought my '98 new and have put 249k fairly trouble free miles on it. Ditto on the fuel pump - lost mine 1500 miles from home and paid the price. Ride is uncomparable - I ordered a decked out 2wd with 5.7 and tow package and sound system - better road rig than a Caddy! Going to keep it for some time to come - better than a new one.

love this truck,had a few basic repairs,but engine and transmission have been awesome.
