LEARN THE MAIN CAUSES OF A BAD VOLVO XC90 WATER PUMP FROM THE EXPERTS OF PINEVILLE
THE WATER PUMP IS THE MAIN COMPONENT OF YOUR CAR'S ENGINE COOLING SYSTEM.
IT CIRCULATES THE COOLANT THROUGHOUT THE ENTIRE COOLING SYSTEM AND MAINTAINS A CONSTANT COOLANT FLOW RATE.
AND IF YOU OWN A VOLVO XC90, THEN GIVE MORE IMPORTANCE TO THE WATER PUMP.
DRY ROTATION OF THE WATER PUMP CAN PERMANENTLY DAMAGE THE RINGS LEADING TO COOLANT LEAKAGE.
HERE ARE THE MAIN CAUSES THAT HELP YOUR VOLVO XC90 WATER PUMP TO GO BAD.
CORROSION
THE WATER PUMP IN YOUR VOLVO XC90 CAN FAIL PREMATURELY DUE TO CORROSION INSIDE THE COOLING SYSTEM.
THE FAILURE CAN ALSO FROM AN IMBALANCED WATER-PUMP SHAFT.
AND IF THE FAN BLADE IS BENT, IT WILL LEAD TO VIBRATIONS WHICH CAN LEAD TO THE SHAFT CRACKING OR BREAKING.
EXCESSIVE TENSION ON A FAN BELT OR SERPENTINE BELT ALSO CAN OVERLOAD THE WATER-PUMP SHAFT BEARINGS AND CAUSE THE PUMP TO FAIL.
CAVITATION
WATER PUMPS ALSO CAN GET DAMAGED DUE TO CAVITATION INSIDE THE COOLANT SYSTEM.
THE MOVEMENT OF THE IMPELLER BLADES IN THE COOLANT CAN CREATE A FLOW THAT GENERATES CAVITATION.
THE PUMP GENERATES SUCTION GREATER THAN THE OUTPUT AND LEADS TO VOIDS THAT TURN INTO CAVITATION.
THE TYPICAL SIGNS OF CAVITATION INCLUDE OVERHEATING AND LEAKAGE FROM THE WEEP HOLE OF THE PUMP.
BAD SEAL
IMPROPER USE OF SEALS CAN EASILY CAUSE THE WATER PUMP TO BE BADLY SEALED AND DAMAGE OTHER SENSITIVE COMPONENTS.
IN A VOLVO XC90, WATER PUMPS TYPICALLY USES A UNITIZED SEAL TO SUPPORT THE SHAFT, ALONG WITH A CERAMIC SEAL.
USUALLY, CONTAMINANTS THAT CIRCULATE WITH THE COOLANT ARE ABRASIVE ENOUGH TO ACT AGAINST THE SEAL AND EVENTUALLY WILL CAUSE A FAILURE AT THE SEAL.
YOU WILL NOTICE A SIGN OF SEAL WEAR OR COOLANT LEAKING AROUND THE PUMP HOUSING OR SHAFT.
WORN BEARINGS
YOU CANNOT IGNORE THE RELATIONSHIP BETWEEN THE WATER PUMP AND THE BEARINGS.
A WORN OR IMPROPERLY INSTALLED BEARING MAY CAUSE THE WATER PUMP TO CEASE AND FAIL PREMATURELY.
GENERALLY, THE WATER PUMPS MOVE A LARGE AMOUNT OF COOLANT, AND THEY CAN WEAR OUT OVER TIME.
AND IF YOU FEEL ANY DAMAGE IS DONE, GET YOUR VOLVO XC90 CHECKED BY A PROFESSIONAL IN PINEVILLE.
IMPROPER TENSION
WHEN THERE IS IMPROPER BELT TENSION, IT CAN BEND THE IMPELLER SHAFT.
IF THE IMPELLER LOOKS CORRODED, GET A GOOD COOLANT FLUSH AND REFILL THE COOLANT RESERVOIR.
WORN BELTS AND TENSIONERS CAN CAUSE A LOOSE BELT THAT MAY BREAK OR POP-OFF.
ALSO, IF THE BELT IS TOO LOOSE, IT CAN SLIP AND NOT ALLOW THE PUMP TO TURN SLOWLY, RESULTING IN THE OVERHEATING OF THE ENGINE.
