Sounds like the water pump, it will fling coolant as it leaks when the engine is running, also check the heater hoses and if coolant seems to come from the bottom of car and not the engine then it is a heater core leak.

I keep putting coolant in my 97 jeep cherokee. It isn't leaking, and I checked the oil and its not leaking into the oil either.. could this be the water pump or what?!


Could be waterpump. There's a small "weep" hole in bottom of waterpump. (it's an early warning system to catch seal leak before pump bearing seizes) Check closely lower side of pump and also check pass side floor/carpet for possible heater core leak. You're not seeing white smoke from exhaust are you... if so, might be head gasket leak.

Im always having to put antifreeze in once a week. The way i know it needs it is when temp. gauge surges all the way up then it comes back down. No visible sign on any leaks any where. When i drive to...


Take a close inspection to your waterpump. Pump has a "weep" hole in bottom side of casting. It's an early warning system to detect seal leak before waterpump seizes up and does major damage. It could be so slight that coolant is blowing back along oil pan. That would be where I'd start. Do you smell coolant inside the rig? If so, check passenger floor up to firewall for dampness in carpet - indicating heater core leak.

Loosing antifreeze and I can't find the leak oil is clean and exhaust looks OK not white smoke. Hvae a 91 Grand Marquis


check the carpet under the heater core in the interior. Check the radiator overflow bottle--sometimes they get a small crack at the bottom and weep out coolant. Check for any heater hose or other coolant hose clamp to be weeping coolant onto hot exhaust parts. The coolant will evaporate and you'll never see a puddle. The best time to check is just after engine shut down when coolant temp and pressure is highest.

Coolant is leaking ,i have to fill it everyday.hardly any heat. what can i do? it seems like its shooting the coolant out somewhere on the right side of the motor.


It's probably the waterpump, it's right where you describe. They are pretty cheap and easy to do so even if you have a shop do it, it should not cost that much. Have it repaired before the engine is damaged from over-heating.

HEAT NOT BLOWING HOT ENOUGH


First check coolant level and strength. If good condition most likely stuck open thermostat, just follow the upper rad hose to the engine. Remove the throttle cable bracket to access the 2 bolts holding the thermostat housing to top of engine. Make sure engine is cold before removing, you will loss a little coolant when replacing. Other causes could be plugged heater core, with engine running at operating temperature on gage. Follow the 2 heater hoses the the right side firewall (where they go thru into cab) one should be hot and the other warm (if the outlet is cold, heater core is plugged). The waterpump and cooling fan are direct drive off the engine and not usually an issue on this vehicle.

1990 honda accord temp gauge above hot limit.


Hi there,

Firstly - DO NOT run engine, when guage reads hot, as this will cause costly damage to head gasket & alloy engine head.

The fact that guage takes 1min to read HOT, would confirm the guage IS working properly.

So, other components which are likely to cause hot readings (in this order) are:

- lack of coolant (or leakage somewhere): is there sufficient green coolant at the correct level? Top up mixture to correct level. Repair any leaks.

- collapsed radiator hose: when engine is cold, start engine, then quickly watch both upper & lower radiator hoses to see if either begins to flex inwards (collapse). Replace if either hose is collapsed.

- bad/incorrect thermostat rating : when replacing thermostats, you must ensure it is of the SAME temp rating (they all differ).

- Incorrect Temp sensor rating: the ratings of this sensor must be within manufacturer's spec's.

- bad waterpump: the engine relies on the waterpump to distribute the coolant throughout the entire system. If waterpump is faulty, coolant will not flow quick enough, causing overheating.

If you still believe all of the above components are OK, then have your cooling system "pressure tested". This test should be done, before looking further at other electrical components.

Cheers,

My 2000 Pontiac Grand am GT is overheating and im getting no heat from my heater. I've tried just adding coolant but it hasnt helped. I took it in to the mechanic and he thought i needed a new thermostat...


PAST BY THE LOCAL AUTO PART STORE AND GET NEW COOLANT RESERVIOR CAB MAKE SURE CLOSE NICE EVEN AND DONT FORGET THE CHECK COOLANT LEVEL. RUN THE CAR AND WAIT TILL REACH THE NORMAL OPERATION TEMP. TURN THE HEAT ON HIGHEST LEVEL GO TO ENGINE DEPARTMENT ON PASSENGER SIDE NEXT TO WATER PUMP TOP OF THE COOLANT BY PASS METAL PIPE HAS BLEED VALVE USE NUMBER 8 WRENCH MAKE IT LOSE LITTLE BE BECARE FULL WILL BE HOT. WAIT TILL COOLANT START COME OUT WITH OUT AIR MAKE THIS STEP 3-4 TIME CHECK EYE ON TEMP. GAUGE AND HEATER TEMP. USE ONLY DEXCOOL.

Thermostat?


It actually sounds to me like you're low on coolant. My Jeep leaks coolant and whenever it gets low the temp gauge will go real high and then drop, and the heater doesn't work well. This is because the cooling system of your car is supposed to be a closed system, full of coolant and no air. When coolant leaks out, the space it used to occupy is now occupied by air, which does not transfer heat well. When 'air' is passing through your cooling system, no heat can be transferred from your engine to the heater and radiator, resulting in a hot engine and no heat at the heater. Then when a pocket of water passes through the system, the temperature gauge quickly falls as the water absorbs the heat from the engine. The hot water that cools the engine is where the heater gets it's heat from as well, so when water passes through the heater core, the heater works, but when it's filled with air, it doesn't.

Hot water runs through the heater core regardless of whether or not your thermostat is open or closed. That's why your heater works in the winter even before the engine is at normal operating temperature. The fact that the heater stops working is a good sign that the thermostat is probably not the culprit.

As for the water pump. If the water pump was bad, your temp gauge would go into the red and stay there. Water pumps generally don't work intermittently. Either it's good and ot works, or it's bad and it doesn't.

However, if you are in fact low on water, as I suspect, it means you probably have a leak somewhere. The leak could be in the water pump housing gasket, so depending on where you take it for repairs, they may try to sell you a new water pump anyhow. So just beware of that.

1996 Jeep cherokee, leaking coolant when cold/ hot ok.


waterpump houseing/shaft seal is on the way out hence the water/coolant, running along the block. when hot the seal does so, when cold and depressurising seal doesnt.
