Question about Plumbing

1 Answer

I have a leaking radiator. The radiator leaks when the thermostat is put into the 'closed' or 'off' position. The leak occurs from the knut below the thermostat. I have tried to tighten this knut but it wont move. I would have presumed that a radiator would leak when in the 'on' position but mine seems to do the opposite!

I keep geting a low coolant indicator when it first starts in the morningalso it keeps overflowing and boiling our of the overflow tank. This happens even when ythe coolant level is below full.


Either the thermostat is stuck in the closed position...or the engine cooling system cannot pressurize...both will cause an overheat condition.
A blown head gasket can cause overheat condition as well as fluid loss (boil over)

I'd maybe remove the thermostat and either just replace it or not have a thermostat installed just to see if it still boils over. If it boils over with no thermostat installed then you're getting into possible leak in cooling system...i.e. water pump weep hole, hose or radiator leak...or a blown head gasket.

Hope this helps...

My 1999 Alero must have a leak somewhere because the thermostat gauge rises every few days. I put coolant in it at least 1 a week. I had a new water pump and thermostat put on it, but it is still...


CHECK AROUND WATER PUMP AREA.AND THERMOSTAT HOUSING FOR LEAKS.THE MECHANIC WHO PUT THE WATER PUMP ON MAY FORGOT TO PUT SEALANT ON BOTH SIDES OF THE WATER PUMP GASKET CAUSING LEAKS.LOOK AROUND THERMOSTAT HOUSING FOR LEAKING.IF THERMOSTAT SEAL WAS DAMAGE DURING INSTALLATION IT WILL CAUSE LEAKING.IF ALL LOOKS GOOD CHECK FOR COOLANT LEAKS AROUND RADIATOR .CHECK RADIATOR TOP AND BOTTOM HOSES FOR LEAKS AND CHECK HEATER PIPES AND HEATER CORES HOSES FOR LEAKS.IF ALL HOSES GOOD.CHECK FOR LEAKING CORE PLUGS.

Engine hot temperature high loosing colant


Check for radiator leaks, hose leaks, try to locate the area were the leak is occuring. You may need a new thermostat. If you can locate were the leak is, chances are you'll find the area in need of repair.If coolant is running from small line " hose from radiator or coolant bottle", could be a faulty thermostat.

OVERHEATING


This could be a multitude of things:

Stuck closed thermostat.

Cooling fan not coming on.

Clogged radiator.

Low on coolant.

Water pump failing/leaking.

Head gasket blown, leaking exhaust into antifreeze.

Clogged catalytic converter.

Thermostat: If the Van heats up, then feel the upper radiator hose. If it's cold, then your thermostat is closed. Replace thermostat.

Coolant: If low, simply fill with distilled water and coolant. Low levels will let engine over heat.

Radiator: If there are cold-to-the-touch spots on the radiator after it should be warmed up, then a clogged is probably occuring. Have radiator flushed.

Head Gasket: If you smell exhaust fumes in your coolant reservois tank, then you got a blown head gasket.

Cat Converter: Only can be tested if off the car. Or you could try a non-contact thermometer. These are also good to testing cold spot on radiator or if thermostats are open.

Cooling fan: If mechanical it'll be spinning. If electrical, it should come on automatically with the A/C, or when it gets hot.

Water pump: Will be leaking from the front if it needs replaced. On a van, it's a tough job.

Good luck!

Running Hot


you need to have a pressure check don on the radiator. this will pinpoint the leak if you dont see any leaks externally it could be a head gasket or a manifold gasket but the simplest thing to check is the thermostat. it may stuck in the close position and not letting you antifreeze circulate

2.3l ranger keeps overheating, been through two radiators already.


Hello Ranger Joe, eight months and two radiators is very uncommon. Question, Have you visually confirmed the leak in the radiators or is the leak near the hose connections? Replacing the radiator, cap, water pump, & the thermostat leaves only two others, the hoses and the engine block/heads. Far fitched will be something or somebody poking holes in the radiator.

Leaking anti-freeze or water


Change out your thermostat gasket and upper radiator hose. This should fix the problem.

Leaking Antifreeze


Are you getting water in the oil?
Are you burning white smoke?

Depending on the moter size, it could be an intake gasket leaking as well.

2.0 has thermostat mounted to head and hose to Radiator, 2.4 has thermostat below radiator cap.

Best thing to do is have Radiator pressure test done and see where the leak is for sure. There are dyes that you can add to the radiator and you can see leaks with UV light.
