Have u checked the fans and fan relays to see if working properly was a flush done [possible blockage in engine passages]

Posted on Dec 04, 2012

  • jessica Dec 04, 2012

    No I haven't checked the fans...I had a leak in my old radiator and I used the stop leak with the pellets in it just to fix it until I got the new radiator and before I bought the stop leak I did a flush for the radiator. But that is all that has been done.

SOURCE: Thermostat on 2002 Chevy Impala

the best thing to get is the Haynes manual for your car at advanced auto or autozone or somewhere like that and the book will tell you how to take everything apart and put it back. i think the manual is about $16.00

SOURCE: 2004 Jeep wrangler 4.0 - 6cyl overheating

I had the same overheating problem in my jeep ! My problem was finaly found out to be the clutch in my fan its a different kind of clutch system it work as this. When your jeep gets warmer the tighter your fan clutch gets .While cool your fan moves slowly. now to test your clutch just warm up your jeep and rev it up a bit if your fan dose not pick up speed then it is sliping.What will come out of this is that you fan will the seez and run full all the time. if you jeep dose not overheat wile moving then it is not your thermo stat period.

SOURCE: ford ranger truck overheating

I have had this happen with my ranger. Changed everything I could to try to fix the over heating. It turned out that I had a small leak in my head gasket and it was allowing exsaust gas to go into the cooling system witch was over pressurizing it. Also the air from the exsaust will heat up much faster than liquid making your thermostat to read hot and will not be able to blow hot air in the cab because there is no liquid going to the heater core. This happened to me when my blet came off and I tryed to make it home. If you had it over heat for a long peirod of time it may have ripped the head gasket.

SOURCE: 95 CHEVY IMPALA SS RUNNIN HOT

You may want to try checking the fans. I have a 95 ss with the same problem. If you disconnect the MAF and then start the vehicle the electric fans will come on. Try driving it like that. That will atleast narrow down your search. If that makes it run cooler then its most likely a problem with the fans. Either a relay or fan switch. Blown head gaskets will usually result in the coolant and oil mixing. Check your fluids for signs of that. I have also read that the radiator cap not sealing properly can cause the coolant system to lose pressure. This reduces the systems ability to circulate the coolant causing it to run hotter. Thats an easy fix. I have not fixed mine yet. I just havent had time. That should be a good place to start. As far as getting a new engine or head gasket they are both really expensive fixes so try any other way u can to fix it first. Hope this helps.

hi jasso, I would recommend checking the water pump if you see no flow in the radiator. Make sure when you fill up the cooling system, that you fill it cold, and that the vent screw in the radiator is loose. fill system until fluid comes out the vent screw. tighten the screw, start the car and have someone run at 1500rpm and check for flow.also, make sure that you have your temp setting full hot and blower on middle speed so that you don't trap air in the heater core.

2004 impala overheating. How do I know if my water pump is bad?


Let the engine cool down then remove the radiator cap. With the cap off, start the engine and let it idle. Watch the water in the radiator. As the engine heats up, the water will rise as it expands during heating. When the thermostat opens, (and this may be your problem) the level will drop, and you will be able to see the water recirculating through the radiator. If this doesn't happen, the thermostat is not opening (stuck closed). If you can see the water recirculating when you start the cold engine, then the thermostat is stuck open. Either condition will cause overheating. Start with the easy fix first (thermostat) before going to the water pump.

Chevy impala overheating


If it is running hot in a short distance, I would check the water pump to find out if it is pumping coolant thru the system. It should run for 5-10 min before the thermostat would be a problem.

If you have changed the water pump AND the radiator AND the thermostat and still have the problem then the hoses should be checked to be sure they are not collapsing, also make sure that the coolant is 50/50 water and coolant and the thermostat is installed right.

Hello and welcome to FixYa! If you have overheating problem, it can lead to multipleissues. You may be running on low coolant that's why the vehicle overheats. Ifthat's the case, please add coolant and make sure that it sits on the rightlevel, too much coolant can cause overheating too for coolant will overflow. The vehicle may have a faulty or worn out radiator blowermotor that's why it overheats. If that's the case then you will need a blowermotor replacement to resolve the issue. If the radiator is clogged with dirt and rusts this issueoccurs too. The coolant doesn't flow normally on the cooling system if it'sclogged. If that's the case, I strongly suggest that you have the radiatorflushed to drain out dirt and rusts. If you think that the radiator served youenough then it's better to have it replaced. Please do check the radiator hoses, If you have worn outhoses it can cause coolant leakage which can result to overheating. A tiny holeis good enough for the vehicle to overheat. A faulty thermostat sensor can cause the issue too. If youhave worn out thermostat, the fan may not trigger that's why the fan won't workwhen under stressed conditions. A blown radiator blower fuse can cause thisissue too so I suggest that you check the radiator blower fuse and replace itwhen necessary. What causes the radiator blower fan fuse to blow? It's becauseof a failing radiator blower motor, If that's the case have the radiator blowerfan motor replaced. If the fluid in radiator doesn't circulate then it meansthat you have a blown head gasket or a faulty water pump. I suggest that you gofor the water pump replacement first specially if you think that it's near theend of it's service life. Usually, water pops out the radiator when engine isreved (a sign of faulty water pump and possible blown head gasket). Hope you find this information helpful enough and thank youfor using FixYa! Have a good one!

Over heating i have water in the radiator do i have to put some radiator fluid in so it wont over heat?


Hi,
You need to check that the water is flowing first, with the engine cold remove the radiator cap and start the engine let it run until it gets warm, once it is warm leave it going until you can see the water flowing. If you can't see it flowing after 10-15 mins of the engine running then you will need to replace the thermostat.
If the water isn't flowing then you have a problem with the water pump and you will need to replace this.
Hope this has helped

Overheating 2001 chevy impala


Believe it or not, new thermostats can be bad. Did you maybe get some adhesive on the thermostat preventing it to open fully? Is the thermostat installed with the crown up? The only other thing that I can think of, if it's a closed cooling system and the wrong radiator cap is installed, it won't hold the pressure, therefor overheating. The other thing may be the water pump. Many times the impellers will wear down internally causing to low of water flow.

Engine light comes on and says engine overheating


Could be three things: Hopefully the first...
1. radiator fan not blowing. (most likely)
2. Radiator clogged (not likely)
3. Head gasket blown... (very possible)

If #1, system cannot detect fan not blowing. It may be the fuse or the relay switch, disconnecetd wire at fan, or burned-out fan motor.
If #2, Flush radiator
If #3, you will see WHITE smoke out the tailpipe and excessive water drops.
Your new oil will have a "milky" look (check the oil dipstick). That is water.
When engine is COLD, remove radiator cap and start car. You will notice high-pressure "bubbles" squirt out of the radiator, even before the engine warms up.

I hope it is #1. and that this is helpful.
