Use a pressure testing kit that is used to flush the radiator. It will hook up to the garden hose and force water through the radiator. If water comes out from the bottom tube of the radiator as fast as it goes in (well, almost as fast) there is NO clog. If it comes out slowly, get some radiator flushing material and flush the whole system including the heater core!

Overheating when stopped. New thermostat, new head gaskets. Antifreeze will be boiling and spill out the reservoir no matter what antifreeze level is.

Check your fan, if it is electric fan, make sure it comes on. Check if your radiator is blocked or clogged, Remove it and get it inspected & cleaned by a radiator repair shop

How can I tell if my radiator is clogged. I replaced my thermostat and water pump but its still overheating

only good way to check is flush the radiator with hose pipe, then reverse flush it. This should remove any blockages. No easy way to check if it's clogged although you may find a big difference in temperatures between the inlet hose and the outlet hose.

Toyota emina keeps overheating

before saying that might have a cracked cylinder head or blown gasket,I recommend you to check the following for clearing some doubts. Have you checked whether the radiator is clogged?,have you checked whether the matrix is not clogged? have you bled the cooling system? Also check when you accelerating with radiator cap on if the radiator hose upper expands,if so means that the engine coolant is pressurized and the problem is the cylinder head.

Clogged coolant passages in engine block and head.
Possibly clogged radiator. Check radiator fan on-time.
if clogged, use a heavy duty cleaner. Check timing.

Car is over heating, boiling in the overflow, this after 5km's the oil looks fine ?????? help

Check your coolant levels and make sure the hose between the coolant reservoir and the radiator aren't clogged. The cooling fan on the radiator may not be directly driven by the serpentine belt and may be on a clutch. If the clutch is broken the fan won't cool the radiator and the radiator won't cool the car. Get the car good and hot and see if the fan kicks on. To temporarily relieve the overheating in the engine, turn the heat on in your car.

The car is over heating--radiator needs water added every day--no visible leaks.

Check ur RADiATOR if its CLOGGED! Checking it by means of TOUCHiNG the BOTTOM PART after running ur engine for 30 min. If the bottom part is not the same as the TOP part of the radiator, it means its CLOGGED and u need to bring to ur nearest garage mechanic to FLUSH OUT or internally clean the radiator assembly! Check also the RADiATOR FAN if it works in a certain temperature! If can't see any leakage, as u say, 'cause of high temperature of ur engine, ur COOLANT goes to the coolant reservoir and overflowing it every time ur engine HEATS UP! Check also the RADiATOR CAP, if the seals are damage or the spring is all corroded up, water heats up and goes thru ur reservoir and doesn't come back to ur radiator when engine colds down, radiator caps FAULT!
Hope that might help u out! Taaah!

Seems to be overheating when A/C is running

Check that radiator cooling fans come on when A/C is on, check coolant level, check for stuck thermostat, clogged radiator, Have you ever flushed out your radiator and changed coolant?

96 darango overheating

most of the times its your radiator. you must have it cleaned out and sometimes its your hoses that collapse. take it to a radiator shop and have them clean out the radiator and they should tell you if the radiator was clogged up. if it isn't clogged up your next bet is the hoses on the rradiator.
