Question about Cars & Trucks

1 Answer

Hi. I replaced the thermo water housing(whole unit) as it had a leak. The car now over heats to about 110deg but only on the hi way. In traffic she is perfect at 90deg. Is there an issue with the thermostat?

Due to the thermo housing change , you may have created an air pocket in your system. You will have to bleed the air out, and fill system to proper level. GOOD LUCK FRIEND.

SOURCE: Hi, I have a 2001 nissan

hi. was just looking at your problem of (sentra) overheating and actually, i am a mechanic for nissan and have changed many head gaskets for this particular vehicle equipped with 1.8 liter motor and found that they are notorious for this problem of faulty head gasket's.Unless you did't properly bleed the system,which i doubt because you seem mechanically inclined since you already changed every other part of the system,i would't doubt that this is the problem.Anyway, by the time you read this, you have probably already found this out..Just thought i would let you know this info.Good luck! the way,if you haven't already changed you cam and crank sensors,do that too,before you get stuck and get the part's at the dealer!!!!-they are redesigned from the old one's!!just some advise to try to help you out!!!

SOURCE: 2002 chryler sebring is leaking anti freeze

It depends on where the leak is coming from. If the water pump is leaking, it has a hole on the bottom of it. You will see a trail of dried anti freeze coming from the bottom of it, indicating a bad water pump. It's best to dry everything off, crank it up and let it come to operating temp and check for where the leak is coming from. It may just be an old hose or loose clamp.

your fluid needs topping up, auto matic transmissions actually use the oil to drive, not friction plates as in normal manual transmissions

In the fan circuit...You have a temp switch screwed on the radiator, a fuze and a relay in the fuze box plus a fan.  Swap the relay with another relay, replace the fuze.  The other fan should come on when the a/c is turned on.  If you fix the fans and it still overheats, you may have a BLOWN HEAD GASKET.  ALSO ARE YOU BLEEDING THE AIR FROM THE SYSTEM?  DO YOU SMELL EXHAUST IN THE COOLANT?

SOURCE: Bublling in the thermostat housing and very hot upper radiator hose

I recommend flushing the radiator thoroughly if not done recently. there seems to be some sort of blockage in the radiator at this time. if you get lots of metal fragments that are flushed out during this flush, i will then recommend a rebuild on the radiator or replacement of the radiator. make sure the cooling fans are cycling on time as well.

My 98 silhouette gets smoke from thermostat area in town not on longer trips?

Hi J, Let's be sure of a couple of things first-off.
1) are you seeing smoke (from burning oil) or steam (from a possible coolant leak) near the thermo, which contains coolant?
2) are you sure the condition isn't happening all the time, and when on "long trips," which I assume you mean, while driving faster on the freeway, and when in slower traffic, you can see it because there's not as much air flowing in the engine area due to lower vehicle speed? Do you see any coolant residue around the thermo, which could indicate a leak?

Over heating 2001 Mercury Cougar 2.5 manual

is it losing water? if not is your fan kicking on? if losing water, place piece of cardboard under veh at night to help pinpoint where water is leaking. if not losing water and fan does'nt come on check fan relay. if loses water and don't see leak over night on cardboard, then water pump is leaking thru weep hole but only after heats up and pressure is on need to replace water pump.

Car not heating changed thermostat flushed and no heat ??

Hi, You could have a bad temperature sensor or sending unit. I would lean more towards the sensor. The sensor controls when the thermostat opens and closes by reading the temp of the engine. The sensor is located somewhere around your thermostat or thermo housing.

The engine fan won't turn off - it's never happened before - don't have the owners manual or I would try to remove a fuse - help please! I guess I'll disconnect the battery for now.

The radiator coolant fan switch is the key here, It'll be mounted either on the radiator or a thermostat housing and controls the cooling fan( large brass unit with 2/3 heavy wires ) ! A replacement will be the best money you ever spent, (OVER HEAT JUST ONCE AND IT'S GAME OVER) . Drain the coolant (and save) when cool/cold and replace thermo rad switch , re fill with saved coolant , check for leaks and bring up to normal enging temp and observe fan operation.Good Luck

Slow leak in radiator or overflow heat blowing cold when stopped

It sounds to me as though you have a thermostat valve problem in the cooling fluid cicuit. The test is to remove it, let it get to room temp. and then place in a cup of boiling hot water. It should open. If it does not, replace. They are fairly inexpensive 5-10$. If you do not know were it is follow the top hose of the rad to the engine block it will be in the housing that the hose clamps to at the block. Caution!!!! when you remove that thermo stat housing you will drip coolant. Catch it in a pail or similar. If you miss the pail, hose down the driveway or whatever because it tastes great to pets but is deadly. ( Ethylene Glycol ).

My 2001 Kia Sportage is overheating. This was a sudden issue. The fan is not turning on and I noticed that the radiator fluid was leaking from a hose below and in between the motor and battery. What could...

first rectify the leakages! then ensure that the thermo sensor is in good condition! if it is then change your engine control unit after checking that the fan are working!
