How To Tell If Your Car Has Blocked Fluid Lines: Three Dead Giveaways You Need Auto Repair Services

The various hoses and lines in your vehicle deliver fluids to many areas of your vehicle. When the lines are blocked, it could cause very serious damage. There are three dead giveaways that reveal you have blocked fuel lines and that you need auto repair services to unblock them.

Auto Liquids Do Not Squirt Out When Hoses Are Detached

A good example of a blocked fluid line is in windshield wiper fluid and the wiper blades. Many times the blockage is found at the point where the hoses connect to the blades and nothing comes out when you try to squirt washer fluid onto your windshield.

Other blockages farther down in other fluid lines can be uncovered by disconnecting the hoses, such as those connected to the transmission fluid or the hose that connects the engine to the radiator. When your vehicle is parked and is cool, you can disconnect these hoses and watch to see if the greenish-yellow coolant of the radiator or the pink fluid from the transmission drip or squirt out. If nothing comes out one or both ends of these hoses, you definitely have a blockage.

The Parts The Fluids Cool Or Keep Slippery Have Problems

Auto fluids are meant to do one of two things: keep parts lubricated or keep parts from overheating. When there is a failure in either of these two departments, it means that there is either something wrong with part itself or the fluids for these parts are not getting from their respective reservoirs through the hoses to the engine parts. An auto service technician can find and diagnose the problem, which may be due to blocked fluid hoses. Just to be on the safe side, a mechanic may replace the supposed damaged part completely.

Pressure Builds Up Behind The Blockages In The Fluid Hoses And Splits Them

If you have blocked auto fluid lines, they will do the same thing that blocked arteries in the human body do. They will swell up behind the blockage until the pressure is released, either through cracking and splitting open, or by popping/exploding right behind the blockage in the line. If you see any of your fluid lines begin to swell and/or you see lines splitting or popping open, you need to get your car or truck to auto repair services right away and get the hoses replaced. Blockages often result in the total replacement of auto fluid lines.
