1996 nissan altima no cabin heat, new radiator, flushed and filled, top hose hot, lower hose cold, newer thermostat checked good

I just replaced the radiator after the old one cracked at the top near the cap, gimped the car home (overheating the whole way but stopping every so often to let engine cool down before going for another stint) flushed the system with hose and refilled, bled system, but there is still no heat in the cabin and the top hose gets hot and the lower hose stays cold. replaced thermostat a month ago and checked today to see if it is opening and all is good. Can't seem to figure out what to do.

HI Anon.
Remove your radiator cap (WHEN ENGINE IS COLD), run the motor and let it warm up a minute or two, have someone rev the engine a little while looking into the radiator. If the water goes down and/or you see the water moving, your water pump is good. If not this means that your water pump is bad and is not moving enough water through the system. Try Removing your thermostat and run the engine without it. Keep checking the radiator hoses to see if they are the same temperature. If they are not the same temperature the water pump is bad. If they are the same temperature your thermostat is more than likely the culprit. Hope this helps.

SOURCE: Engine runs hot on 2001 Stratus R/T 3.0L V6

Hello, as previously suggested by my collegue it appears you have an air lock. Have you tried parking the vehicle on level ground, from cold with radiator cap off start the car and leave it idling. Make sure the fluid/coolant levels are o.k. and let the engine reach operating temp. Keep some warm water handy and watch/listen the water/coolant system (Keep a safe/sensible distance from radiator) hopefully after a while the system will bubble and boil up let it settle for a few seconds and then top up with very warm water do this until it hopefully stops belching out of radiator. Replace cap and hopefully top and bottom hoses will be warm. Oh! nearly forgot keep all heater controls on hot with blower on full..(Inside the vehicle)
Finally I'm not joshing but is the thermostat in the right way round and functioning correctly? to test drop it in some boiling water it should open almost immeadiatly.
sorry for the epic but I'm here to help and hopefully save you time and money.
Good luck and a Happy New Year to you and your family!

SOURCE: The heat in my 1992 Jeep Wangler is not working.

Hi!
It appears we have an Air lock scenario and you will need to perform a system Bleed.
Park the vehicle on level ground, when cold remove coolant filler cap, start engine and leave to idle, turn heater on full and blower to max. When engine reaches operating temperature watch and listen near coolant filler, keep clear as gurgling and hopefully a boil over should occur. Top up with very warm coolant and wait as it may do it again.
Check for heat inside vehicle if warm replace coolant cap but keep an eye on temperature gauge as the ~Air lock may have moved on from heater matrix/core so proceedure needs to be carried out again from COLD.
If persistent boil ups/over attention must made in the cylinder head
or gasket area, or possibly water pump?

SOURCE: 2004 NISSAN ALTIMA 2.5 NO CABIN HEAT..ENGINE AT OPERATING TEMP.

If the engine is not over heating than most lilely it isn't the thermostat or waterpump that is causing the problem. Check the heater hose coming out of the manifold and see if it is warm to hot. Next check the return line from the heater if it is still cold or moch cooler than the inlet, the most possible problem is the heater water control valve if this model has one or possible the core of the heater is plugg with slime cause by some antifreezes setting during the summer months while not being used. If this is the case than remove tihe two hoses and back flush the heater core with water pressure until it runs clear. I have had this problem before and this cured my problem. I also had to flush the engine and radatior also. Hope this help. .

Replace the bad radiator hose first.  Second- get you special formulated anti-freeze dye from the auto store and pour it into the radiator.  Third- make sure you got all the air pockets out of your system, cause the coolant system won't work with air pockets in it.  Fourth- Check for leaks by looking for the colored dye.  If it's not the radiator hose, then could possibly be a pin hole in your radiator.  Would suggest replacing all the radiator hoses at the same time while you got the coolant system disconnected, cause you don't want to have to come back and replace another hose in a few months.

Probably not water pump. Engine is notourious for vapour lock.
Cooling system must be blead of air before thermostat will work. Cool bottom rad hose is a dead give away. If you are still watching this forum reply , and I will walk you through the only way I know how to make it work properly. It's actually easy if you do it my way. I have worked on lots of cars , and this engine was the hardest to bleed out. Did one Yesterday , and works perfect.

I have a 1998 dodge and the temperature hand keep saying its is running hot but I don't see any steam or anti freeze coming out of it.


when you see steam ,it is too late
If you have a viscous fan hub replace it as it will get to overheating, especially at stop lights , slow traffic and going up hills slowly but with high rpms.

check for low coolant level make sure coolant system been bleed from air.make radiator full coolant and coolant reservoir on the full cold mark.if all is good the cooling fan relay could be bad or the engine coolant temperature sensor could be faulty.

My 2000 plymouth neon is overheating, it has a leak near the radiator cap


if you keep going , instead of needing a new radiator , you will need another engine
temp gauges do not read with out water to make them work and if the temp keeps going up after refilling the radiator , it could be a head gasket or cracked head result

I have an 1998 Subaru Forester - it has overheated three times in five days. The coolant is full and new, the thermostat was replaced today. The old thermostat spring was fully extended, after replacing...


Subarus can be challenging to "burp" Sometimes it takes several attempts to get the air out of the system. The procedure is simple. Top off the radiator, squeeze the hose a few times to help get the air out, replace the cap and start the car. let it idle or drive slowly near home with the heat on high. once the temp gauge begins to rise, if there is no heat get the car back to the driveway before the temp gauge gets half way. Shut the engine off wait for it to cool, at least 10 minutes. Then check the radiator again. If there is still air top off again and repeat. After 3 or 4 attempts if there is still air and or the coolant reservoir seems to be filling, try replacing the radiator cap. If this doesn't solve the problem, It may be a head gasket.

I have considerable steam coming from the area of the rad cap. Temp gauge doesn`t indicate any overheating issues and the coolant reservoir is within the desired fill. However, coolant reservoir it has...


It may be the radiator cap itself, but is most likely a crack that has formed around of near the radiator, causing steam to exit from this area. It seems like it is a small leak, otherwise the coolant loss would not be so gradual. Radiator replacement will most likely solve this problem after the radiator is inspected and a crack is found. I do not recommend the use of Stop leak to correct leaking radiators, in the long run, they do more harm than good.

Leaking from the very top of my radiator down and dripping to ground, but vehicle not overheating on gauge yet. does the whole radiator need replacing or is this a gasket problem?


make sure its not the radiator cap or the overflow hose. if radiator is cracked or leaking at the tank seal then radiator must be replaced.

Overheating when driving no mixing of the coolant and oil


The three most likely thing's cause overheating are faulty thermostat,electric fan or clogged radiator. Only at has been overheat so much it boils dry that it will cause engine trouble. Most common problem's are blown cylinder head gasket or a cracked cylinder head.
mixing coolant and water depends on where the gasket has blown or head is cracked. You will first need to check if it actually is overheating. The reason is. If the head is cracked or gasket blown then you can get a false boiling which is compresion from the cylinders blows through the crack in the head or gasket causing the coolant to blow out of the radiator cap.Fill the radiator to the top leave the cap off then start the engine.If the water blows out then you will need to remove the cylinder head check the gasket is ok. If its damaged replace if not get the head checked for crack's. If no water blow's when you start it check the thermostat is working properly. To check the thermostat put it a in a saucepan cover it with water bring the water to the boil. It should open before the water boil's but near boiling-point. If its ok then start the engine again leave it running until it boils and check the fan is running. If that's ok then its radiator problem. Their is no way to check if the radiator is ok you will need to get a new one. One last point. If the cylinder head or gasket are faulty it was caused by overheating so by just fixing the cylinder head problem is not a cure it will overheat again. Check the three things I mentioned at the begining and told you how to check them. Hope this help's. Cheer's

Plastic radiator repair


I doubt you can actually fix it "yourself", but you can save lots of money by taking it to a radiator shop instead of buying a used or new radiator. They can replace the plastic tank for the bad side, but it is usually the drivers side because this is where the hottest water exits the engine and causes the plastic to crack. I removed the radiator myself and took mine to a shop and they repaired it for $40........cannot repair yourself because the tank has to be crimped on!!!! And radiator "stop leak" products will not work because they are for metal tanks!!!
