One possibility is that the thermostat was replaced with one that opens at a higher temp than the old one. I would suggest driving with cardboard in front of your radiator, cause everybody's doing it, but that's how I cracked my radiator, and sent my cars cooling system straight to hell, so do it at your own risk.AnswerThermostat may be defective, is coolant level up? What is bled properly? Heater core may be partially plugged. I am assuming the the volume (force) of air coming at you is adequete and the temperature is just the problem. How often did you flush the cooling system while you owned it? AnswerSounds like an air lock in the cooling system. Rebleed the system ie. remove the rad cap and let the car idle for a half hour or so. You may see the temp gauge move around a bit, but just make sure it doesn't sky rocket and you will be fine. As well, check around the hose inlets on the engine side for bleeder screws. If any are found open them as they are vital for proper bleeding.Good luck. AnswerThe genuine Mazda thermostat for a 92 protege has a small valve and the normal large valve. It is made to keep the engine quite hot. Third party thermostats often make mazdas run cooler and provide less heat.
A cracked radiator can not be fixed. A cracked radiator needs to be replaced . A mechanic can replace one in a few hours.
you might want to check for a blown head gasket or a cracked head or block. espically if it loosing water out of the radiator with out leaking on the ground.
blown head gasket or even worse, a cracked head or two.. try filling radiator with fluid, then start it up. there should be a pressure relief valve on top of where you replaced the thermostat. crack it till it bleeds all air off, then there should be only fluid. gradually fill your radiator with fluid during this process. if water is spitting out of the fill hole, it's a cracked head
The radiator hose is cracked near the clamp; or the clamp is loose; or the thermostat housing gasket is worn.
It could be a clogged radiator or cracked head or bad head gasket.
You either have a cracked block, blown head gasket, or intake manifold gasket leaking coolant into the engine oil. You have bad problems.
A Nissan Frontier may be overheating because the radiator is cracked. A thermostat failure can also cause it to overheat.
Had the same problem on my 1991 accord. Replace the thermostat, gasket, and radiator cap. Also, get a gallon of coolant if your current coolant has been in there for more than three years. The thermostat is in the engine block. Simply drain coolant, remove the radiator hose from the engine - the hose that goes from the bottom of the radiator into the engine. There may also be a small spount that bolts into the block, remove the bolts and there is the old thermostat.
You probably have a cracked head gasket!!!!! You probably have a cracked head gasket!!!!! Check coolant to see if there is oil in the coolant this will prove it or if you have foam in coolant overflow check coolant resevior cap
mine was the overflow tank. was cracked at the bottom so you couldn't see. it cost me 27 bucks
It means you probably have a bad head gasket or worse, a cracked head.
As far as trouble-shooting, the only things left to check are the tension on the drive belt, broken or cracked fan blades, radiator cap not maintaining pressure (my prime suspect).
Don't know what kind of vehicle you have but a thermostat housing and the clutch are not connected in any way. Need more info.
It could be a head gasket or cracked head. With the engine cold, take the radiator cap off and crank the engine. If the head gasket is bad coolant should shoot out of the radiator. 12 inches to possibly hitting the hood.
Several possibilities in order of expense: thermostat, coolant leak, water pump, plugged radiator, bad head gasket, cracked head, cracked block.
Stuck closed thermostat, cracked head, bad head gasket, low on coolant are some possiblities.
A number of things. The fan relay or temperature switch may be bad (electrical fans), the fan clutch may be worn out (older vehicles), the radiator could be clogged internally, too much debris in front of radiator (air can't get through to cool collant), blown head gasket, or a cracked head. Also the thermostat could have been installed backwards.
There are various things which could cause a cracked radiator. You should try to consult a professional on the matter.
If it's repairable, a reputable radiator shop will be a good resource. They can tell you if the radiator can be repaired or if it must be replaced.
broken radiator hose, cracked radiator, thermostat gone bad (depending on where its located) or water pump
If you replaced some of theses already ignore and go down the line # Not enough coolant # Water pump drivebelt defective or out of adjustment # Radiator core blocked or grille restricted # Thermostat faulty # Electric cooling fans blades broken or cracked # Radiator cap not maintaining proper pressure # Ignition timing incorrect
If the radiator is cracked then the vehicle has ran dry on coolant. This would cause the radiator to crack if there wasn't any coolant.
Oil can't "back-up" into the coolant, they run in separate systems... you wasted money on the radiator, the thermostat is irrellivent, your engine block is probably cracked although it could be a gasket or loose bolts... you need a good mechanic and money
Thermostat, blocked radiator, leaking hoses, rusted impellers on the water pump and the worst possibility, a leaking head gasket/cracked head.
Make sure you do not have a cracked head(s).
