1991 Isuzu Pickup Problems

The heater core may leak coolant, excess coolant loss can result in engine overheating. Our technicians tell us a revised, copper heater is available to replace the original aluminum one.

Some engines may develop an oil leak at the front of the engine, the source is commonly the front crankshaft oil seal. Our technicians tell us a revised front oil seal retainer gasket is available to correct this concern.

1991 Isuzu Pickup Questions

where is the mass air flow sensor located on a 1991 Isuzu 2.3L pickup engine? Picture if possible. New fuel pump and filter. New head and intake gaskets. Starts and runs for about a minute then dies and won't restart for 1/2 hour or so.

Just replaced head gasket and intake manifold gasket. All vacuum lines connected. New plug wires. Back 2 cylinders not firing. Timing set properly.

The e-brake cable ends in a Y and then the cable go to each wheel. There is a stop nut that looks like a lead weight that goes into a holder. How do I loosen the cable so I can put it back into the holder and then how do I tighten it so I can have my E-brake working again.

Thank you,
David C.
