Question about Cars & Trucks

1 Answer

I have a 2003 Chevrolet s10 4cyl that is overheating

I replaced the radiator and water pump, there is no foam or bubbles in the coolant and no steam from the exhaust so I don't believe it is a blown head gasket. It does not overheat in park, only while driving and it quickly cools back down when stopped (like at a stop sign.) Any input or info on known issues is appreciated! Thanks in advance!

    Maybe a blown head gasket.Your belt is turning properly.

    Belt seems fine, no squeaks or squalls, all the pulleys are turning. I guess the next step is check the oil for water, it had a little trouble starting last test and the idle was fluctuating a bit. Any ideas? Thanks for your response thus far!

Check your thermostat to see if it is opening and closing.

SOURCE: my monte carlo overheats when idle but no signs of a blown head gasket nor water in oil. the temp gauge will go up to half way then the radiator fans will come on. when i'm driving it will go down to

When the engine is "over heating" are the radiator cooling fans running on high speed?

Has there been any engine work performed on the vehicle lately?

Let me know.

Well the only thing you haven't replaced is the water pump. The impellar can dislogde from the shaft or completely disinerate. this is not common but I have seen it. Mostly the impellar spinning on the shaft. this is one of those jobs you just have to take it apart and see. No way to check it that I know of.

Changed water pump took out thermostat still overheating


How about more info.
The water pump is almost NEVER the issue unless it.
1) Leaks and leads to loss of coolant
or
2) The impeller has broken off
or
3) Someone has installed the wrong pump.

When does it happen,how quickly,is the radiator fan working,are the radiator external surfaces clean and is airflow unobstructed. Is the coolant a proper 50/50 mix. When starting with a cold engine and the radiator cap off are there bubbles in coolant. Did this happen suddenly or over time.

Sebring overheating 2.7 V 6


This is hard to say without a test. The test is going to be a pressure test of the coolant system. You hook up a cap that has a pump and guage on it and pump the pressure up to the rating on the original cap. Then you watch for leaks. If it was head gasket, you would most likely get coolant in the oil, white smoke (steam in the exhaust) or bubbles in the radiator. If it was the water pump you would have coolant dripping out of the "weep hole" on the pump shaft.

04 impala overheating


Could be a few different things. 1. low coolant level 2. thermostat sticking "replace it" 3. water pump failing. These are the most common things that go wrong. First do this,check coolant level and if ok then replace thermostat. If coolant is low please take time and check for leaks,its going somewhere.....please rate this post and good luck and hope the info helps..

Just replaced my water pump but my car is overheating. could the water pump be defective?


I would say that is possible, but unlikely, if you just put on new one, this could be most likely your thermostat is stuck or just plain bad. If it is over heating instantly, and your sure your water pump is operating correctly, then it could be the thermostat.

Changed bad water pump and timing but car is still overheating causes


Overheating is not always caused by a bad water pump or bad engine firing timing.

The most common causes are:
  • faulty radiator cap: steam/water will be escaping from the caps when engine is hot or oveflow tank overflows or empty!
  • crack cylinder head gasket: check when engine is cold thru radiator cap hole for milky oil in water radiator or large bubbles in radiator water after starting engine. Also check if water steam comes out of exhaust.
  • cylinder head itself: same symtoms as for gasket above.
Hope it helps you find your problems.

Hi my problem in my envoy 2004 is that I'm changed the water pump, fan clutch, radiator, thermostat and it's still overheating and evaporated the coolant on a 80 miles drive. My techs check and says that...


remove radiator cap, run engine, and look for bubbles coming up. Bubbles indicate blown head gasket. Also check exhaust for excess moistness/steam.

Toyota wont start over heated replace the thermostat and radiator cap could it be the water pump is bad how do I tell


if it wont start immediatly after it overheated then you may have blown the head gasket, or melted a coolant temp sensor or other sensor or wire. look closly for the melted stuff. remove radiator cap and fill with water to the top of the rim. have someone crank it and if a air bubbles come out while cranking then a headgasket is most likely blown. some little bubbles at first dont mean nothing. its a steam of bubbles the whole time its being cranked that indicates head gasket

2003 towncountry over heating.replaced rad and thermstat but still over heating what the f cuold it beit has a 3.3 ....the rad had side blown out to begin with replaced it with upper,lower hoses and...


1. With what you have replaced, the only remaining credible explanation is the Water Pump. If the Water Pump is not operating correctly, this will cause overheating. The Radiator -"side blow out"? Did the radiator cap you have on not work. Overheating should cause fluid = steam to blow out the cap and not blow out the side of the radiator.
2. One thing you can do before replacing the Water Pump is to flush your entire system. There could be a blockage in the system. These flushing kits are available at most stores (Walmart or Autoparts Stores) and you can do it yourself.
3. Was the Engine Coolant Temperature Sensor (mounted near the thermostat) also changed out? If this was malfunctioning it could be giving you a false reading.
The Water Pump is the likely culprit if the Van is truely overheating.
Let me know if this helped, or if you have additional questions or information. Feel free to contact me at FixYa.com!
