San Carlos Water Pump Repair Experts


In today’s auto repair industry the water pump is a common maintenance item. It is typically performed if the water pump is leaking or if the timing belt is being replaced. At A+ Japanese Auto Repair we replace hundreds of water pumps a year and have the knowledge and expertise to perform this auto repair service right the first time, every time.

Water Pump - How It Works:

A belt or the timing belt, which is connected to the crankshaft of the engine, drives the water pump. The pump circulates engine coolant (anti-freeze) and water whenever the engine is running. The water pump on today’s vehicles uses centrifugal force to circulate the fluids through the vehicles cooling system. The fluid that leaves the pump flows first through the engine block and cylinder head, then into the HVAC heater core, followed by the radiator and finally back to the pump.

This system is a closed pressurized system when operating normally. Below is a picture of a water pump that is allowing pressure to escape from the cooling system and exit the "weep hole" of the water pump (Fig A.). The second picture shows a simplified view a vehicles cooling system (Fig B.)

Water Pump Failure:

Don't let your water pump leave you stranded!

Typically, if your vehicle is taken to a reputable repair shop they should catch any water pump problems before they become an issue or leave you stranded. Our technicians commonly find water pump seals failing. These seals are a normal part of the wear process in a water pump. Due to this, the manufacturer has drilled a hole known as the “weep hole”. If we see engine coolant leaking or "weeping" from your water pump, then it is time to replace it! Otherwise, you may be stuck on the side of the road with an overheating vehicle in short order. If you find that your vehicle is showing symptoms of overheating problems, it is important that you get to the bottom of this matter because overheating can cause engine damage!
