Im leaking alot of water its not my raditor - Cars & Trucks

mite be a bad head gasket is the exaust have a sweet smell

is it smoking white smoke if it is could be the head gastket or a cracked head and if its not leaking it must be burnning it through the head have a comprecion check done that will tell you alot

Two things it might be the cars raditor fan doesn't work, or the therostate is sticking. ( the gauge does'nt have to be right) the other thing might it need a new raditor cap. Most all cars pust raditor fluild to the overflow when thier shut off if it's low it'll be gas not coolant. the hose between the cap and the tank may have a small leak and it's not sucking the coolant out of the resivoir back to the raditor. The system is designed to be completly full(no air). If you can remove the cap with the car cool and it's not full clear to overflowing the cap or the hose is bad. Being it's nor leaking I'd go with the cap. Get the kind that came with the car not one with a lever.

could be a head gasket (coolant going into exhaust or into oil) pull oil dipstick does it look light brown like the color of a chcolale milkshake if yes u have bad head gasket does exhaust blow white smoke? if yes bad headgasket ? pull radiitor cap off let van run for while does water come out of raditor at a fast rate if yes (possiable ) bad head gasket
also could have leak your not seing look closely around where intake meets heads notice any water trails or see any water leaking ? if yes bad intake gaskets look closely around water pump any trails of water there ? if so bad water pump also check closely around seams of raditor for water trails
after all this u dont see any thing might need to take it to a shop and have it pressure tested (some leaks will only show up under pressure) most shops won' t charge much if anything for this service

If water pump leaking replace both, if not and truck is over heating start with thermostat.

Likely you are overtightening the housing. If you have paper gasket type, try using a double gasket. If "o" ring type, just use the gasket. When tightening the housing take up small amounts on both sides, alternating from one to the other. Tighten till it is firmly mounted but stop there. After filling system, check for leakage. if seepage is noted, take up on bolts one quarter turn or less till drip stops.always alternating from side to side. Unless you have the wrong thermostat in there this pretty much has to work.

1 Inspect Hose Ruptured, Cracked or Leaking Raditor Hose. 2 Inspect Head Gasket Leaking Head Gasket. 3 Inspect Thermostat Thermostat Stuck Closed. 4 Inspect Raditor Cap Worn or Damaged Raditor Cap. 5 Inspect Raditor Raditor Fins Obstructed. 6 Inspect Belt Missing or Broken Water Pump Belt. 7 Inspect Heater Core Heater Core May Be Leaking Antifreeze/Coolant into The Vehicles Floor Area. 8 Inspect Intake Manifold Gasket Leaking, Worn, or Damaged Intake Manifold Gasket. 9 Inspect Cooling Fan Switch - Raditor Faulty Raditor Cooling Fan Sensor/Switch. 9 Inspect Water Pump Leaking Water Pump. 9 Inspect Raditor Fan Motor Faulty Raditor Cooling Fan Motor. 9 Inspect Relay - Raditor Cooling Fan Motor Faulty Cooling Fan Relay. 9 Inspect Fan Blade Broken, Missing, or Faulty Fan Blade(s).

REPLACE THE THERMOSTAT

you may have a water pump that is starting to fail. Look for the water pump that's driven by the fan belt. look at the housing of the water pump there is a relief hole that they drill in the casting and when the pump begins to fail it will drip out this hole. If that's where your leak is, it's time to change the pump.

your radiator could be pluged up internally especially if you havent bought this new. alot of people will dump in a radiator leak stoper if the radiator has a small leak and that is not the right thing to do because the stuff can plug up a lot more than the hole.if you take the radiator out and know of a radiator shop they will flow test your radiator and let you know if it is pluged up internally or not i hope this helps you and please rate my solution.
thank you
