Hi Luke. Thanks for the reply. If I'm understanding you correctly, the other belt (which I believe is on the driver side of the engine, near the front) is referred to as the accessory belt. This belt is the one...

Hi Luke. Thanks for contacting us today. The belt is likely the serpentine belt, which powers the water pump among other systems on your car. It's more than likely that the belt breaking caused the water pump to fail, and...

Hi Johnnie. Thanks for contacting us tonight. If your AC/Heater will not turn on (meaning the blower motor), then it's likely that you have a blown fuse or damaged electrical relay that powers the blower motor is likely the cause....

Hello! That is an extremely common issue that owners of your particular vehicle face. The window malfunction is usually caused by corrosion on the window switch. I suggest that the switch be opened and the circuit board inside of it...

You need to check to see if you have spark to the plugs. Scan the computer to see if crankshaft and camshaft sensors are signaling the computer to spark. If not then replace the defective spark plug. If it's proven...

Do not change the fluid or have it flushed. This could cause the transmission to go out even sooner. There are a load of different additives out there that may or may not work, but when the transmission is going...

A few different faults can cause rough shifting after the vehicle warms up like this. The most likely would be the transmission fluid level, transmission filter, shift solenoids, torque converter, or the transmission linkage. Any of these, once warmed up,...

A few things can cause rough starting like you have described. The usual culprits are issues with the battery, starter, fuel pump, fuel filter, or the ignition switch. I'd recommend enlisting a qualified technician to help you check these components....

The fuel pressure would need to be checked to make sure the pressure regulator is not leaking fuel and that the pressure is correct. You may have a leaking injector if the pressure is okay. I recommend having a certified...

This may be a question of a weak battery or potentially a failing starter relay. If there is a fast ticking sound when turning the key, it is likely that your problem may be a battery that is simply too...

The speedometer operates in correspondence to the speed sensor on the transmission. If all the other gauges are working on the dash then I would start by looking at the speed sensor on the transmission. The sensor generates a signal...

The blower motor only working on high speed is a common symptom of a failing blower motor resistor; but the fact the radio stopped working at the same time is unusual. It's possible that this could still be two separate...

You probably know this already, but I must mention that driving with the faulty power steering is very dangerous. This is definitely not an issue that can wait. The trouble could be in the power steering pump, belt/tensioner, or steering...

Hello there, thank you for asking about your 1991 Oldsmobile Cutlass Calais. With the other items replaced and a continued overheating situation, you may want to consider replacing the coolant water pump. Any time a vehicle overheats, it is a...

This may be a sign of a weak battery, a failing voltage regulator or failing alternator. As you may know, the alternator is responsible for charging the battery while the engine runs by generating amperage and recharging the battery while...

It's possible that your timing chain set is so worn out that the engine either "jumped time" or the timing chain broke. The starter may be turning the crankshaft over, but the camshaft and valve gear is no longer connected...

I would recommend checking for smoke coming from your exhaust. Since you are not able to find a leak and you are positive that the coolant is not mixing with the oil, it is very likely that your engine is...

Hello there, thank you for asking about your 1990 Oldsmobile Cutlass Calais. There can be an issue with the switch itself or the hazard flasher assembly. The flasher is the device that makes the lights blink and a failure here...

Hello there, many different things that can cause the transmission to shift hard. The most common causes include: low fluid level, shift solenoids, torque converter, or the transmission linkage. If you decide to get this fixed, consider enlisting a qualified...

When it is warm, your transmission fluid may be leaking past seals in the transmission and this is due to wear and the transmission would need to be overhauled or replaced to fix the problem. You may be able to...
