How do I check if my car radiator is clogged?

Question

COOLING FLUID IS NOT MOVING, WE INSTALL NEW ENGINE AND THE ENGINE CAME WITH A NEW WATER PUMP, BUT THE CAR IS OVER HEATING. I THINK IS THE RADIATOR, BUT I DON'T KNOW HOW TO CHECK TO SEE IF IS CLOGGED

Answer 1

I'd go with the thermostat !! A radiator very rarely get so clogged that water doesn't circulate. And just because it's said to be new, the water pump could still be bad....?:)z

Answer 3

if you have a new engine then ideally you should have your radiator flushed so it works more effectively. A new engine will perform better than an old one so it produces more heat.And a clogged radiator can't cool the new engine quickly enough, hence the overheating.

Get your radiator flushed, ideally the guys that fitted the new engine should have done it then, and i'm pretty sure that will solve the problem.

please let me kow if it does. Thanks.

Failing that get a new radiator. It's alot cheaper than another engine

Answer 4

the easiest way to check, warm vehicle up, turn vehicle off, run hand from top of radiator down to the bottom, if the bottom is cold
then you have a clogged radiator and if you put a new engine in i would of spent the money on a new radiator. also check fan operation and thermostat operation

Answer 5

One way is to measure the temperature drop across the radiator inlet and outlet hoses using an infrared thermometer. The drop should be in the range of 20 to 45 degrees Fahrenheit.

Answer 6

I bet that it would have to be in need of a good flush. Doesn't cost much money and saves alot in the longrun. If not my next idea would be that you have a collapsed hose. Start the engine and give it throttle while watching what the hoses do. May be just a bad hose spring.

Answer 7

you may desire to place the thermostat lower back in and top off the coolant equipment and , you may desire to pressurize the coolant equipment as much as approximately 18psi and notice if it holds stress , if it does that's sturdy ,you could flush the coolant equipment and positioned 50--50 mixture antifreeze and water , if no longer you r going to have a bl owed head gasket or a cracked head or cracked block , after each and every thing is mounted their could be a bleeder on the thermostat housing to bleed to air out of the equipment once you r finished sturdy luck.

Answer 8

Take out thermostat put a gasket on and new thermostat put back to gether or it could be in upside down you drive with a lower degree thermostat until broke in

Answer 9

an easy way to tell is to check the hose pressure. Once the thermostat opens the pressure in the intake hose should increase giving you enough pressure. make sure the exhaust hose at the bottom has an equal amount of pressure.

Answer 10

Did you check the thermostat? did you add an air conditioner, or add a tranny cooler? Any of these could affect it, I would buy a new one and make sure to get a 4 core
