When you have to replace the oil pump in your car, you have to take into consideration both the cost to replace oil pump itself, and the cost of the labor to put it in, unless you are installing it yourself. The cost of buying new pumps usually costs somewhere between $100 to $300 on average, depending on the model of the car. You have to figure in labor costs of about $200 to $300, as it is an extensive job to put one in and it takes more than an hour or so. So, that brings your total cost to around $300 to $600, depending on who does the installation.
