    lgt for coolant off after fill,afterlg distance boils over, seems eng is not being cooled properly, is it coolant or water pump?

  • george yzguirre Feb 25, 2012

    a water pump has a weep hole on bottom when failing coolant will leak out it is possible the impeller is bad and not rating with shaft. coolant mixture should not matter for testing.bubbles in recovery tank are either compression gas or cap lifting to remove pressure.are cooling fans coming on ?what are the temperatures of top and bottom radiator hose? u could take thermostat out and rem top rad hose and see if water pump push water out of top hose

    also you should pressure test cooling sys and cap autozone should let you borrow a pressure test kit

Head may be warped, radiator may be plugged. Pull all of the spark plugs to see if there is water on them

Just had a go-round with same problem in an 87 Cavalier. Had to take off radiator cap, add coolant, squeeze bottom radiator hose. After no more bubbles, add coolant, squeeze top radiator hose. Squeeze bottom again. Add coolant as needed. The air was because it was run low when the radiator cap gasket failed and coolant boiled out. Never got the overheat notice on digital dash or idiot light. Make sure you have a new radiator cap.

Have a 2000 chevy cavalier. new water pump, new t-stat, new head gasket , new coolant, still running hot

Two ideas.

1. Try a new radiator reservoir cap (trust me, it is very important in holding pressure which keeps the coolant from boiling out).

2. This one you will need an entire weekend to spend on this. You need to remove the thermostat and replace the thermostat housing. pull one of the radiator hoses and attach a garden hose with good pressure. It needs to flush for at least 20 minutes. Then switch directions and flush water where was coming out. Then put it back together and drive until it gets hot. Allow it to cool for 45mins (to prevent engine from cracking due to rapid cooling) and repeat until no crud comes out when flushing.

Hi, I've got a 2000 Plymouth Voyager SE 3.3L V6 with 115,000 miles that recently had the coolant in the reservoir boiling-at which point the engine shut off. This was after about an hour of running. I...

The stop leak most like caused the thermostat to stick closed and caused the over heating which may have blown a head or intake gasket. Have the oil analyzed to see if there is coolant present and if there is you will need to determine which gasket needs replaced. On newer vehicles it's no small job to replace a head or intake gasket os special tools are required.

Indicator light on my 1997 chevy cavalier is lit. I don't have an owners manual that show what the trouble light is. It has an arrow pointing down to a pair of horizontal lines

That is your low coolant lamp. You should check your coolant level with the engine cold. Fill it with coolant if it is low, and inspect it, or have it inspected for a leak, or faulty coolant level sensor.

How much coolant should I put in my 1998 chevy cavalier 2.2 liter?

First, premix coolant with water to get a 50/50 mix of antifreeze and water then just fill your radiator to full and your coolant recovery tank up to the full cold mark (indicator on side of tank) run your car let it reach operating tempature, turn it off let it cool and recheck levels and reservice if necessary. You wouldn't need more than 1 or 1 1/2 gallons of coolant if you premix. Hope that helps.

Car runs hot

Look for low coolant and be sure to have heater on high when checking coolant level...

Hotter than 1/2 way is not necessarily a problem, do the fans cycle on and off?

You are most likely slightly low on coolant. I also suggest that you pressure test the system as well as the cap. Leaks allow coolant to escape and your vehicle is fussy about perfect level...

REMEMBER that when you release the pressure on a cooling system, non boiling coolant can now boil! Many people get seriously hurt... This is NOT indicative of a problem, but rather NORMAL physics, just crank it in to your proceedure...

1997 2.4L Chevy Cavalier LS; Low Coolant Indicator and Temp Gauge

take the cap off of the radiator (whil engine is cold) start and run the vehicle. keep runnig 30mins after the vehicle is hot keeping notice of the rad fluid level.
keeping the cap off will prevent the pressure build up that woiuld keep the air in the system, keep adding water or antifreeze as the level goes down. this may take an hour or so.
also with the cap off, you will be able to see if your water pump is operating correctly. you will visibly be able to see movement in the rad when the pum is engaged.
