Hi,if you are looseing coolent but cant see it under the car,and there is no water inside the foot well from the heater matrix,then I would take the oil filler cap of and see if the oil is a mustard coulor,if not put cap back in place,when the car warms up to the running tempriture if you feel the water pipe that comes from the engine to the radiater it should be hot,and there is another pipe going from the radiater that gose back into the engine is that hot also if not replace phermastate,also to make shore fan is working when car reaches right tempriture,
just food for thought.
but if you can afford to buy a kit wich you attach to the radiater and its like a pump with a gauge,so you pump it up and it pressureises the water systom and if there is aney small leaks that might just not show up,best of luck,let me know what you found.

SOURCE: 2001 jeep grand cherokee. no leaks losing coolant,

Most serious item I see is oil pressure. Put a mechanical gauge on the engine and get an accurate reading. Also make sure that the passage to the sender isn't blocked. If you did the pump yourself, did you find any coolant in the oil? In 99% of all low oil pressure situations, the oil pump has not failed. Rather, either a cam bearing or crank/rod bearing is worn. You do not have to have one spun or completely worn out bearing. Even wear of all bearings that is somewhat excessive can bleed off enough pressure to cause problems (plastigage the engine bearings to determine wear).
As far as coolant loss. A cylinder head gasket can fail between cylinders, into a water passage, into an oil passage or any combination of those and externally as well. The cylinder heads on engines beginning in about '98 are prone to "micro-cracking" which can lead to all kinds of hard to diagnose coolant loss problems. It may help if you have a shop do a dye test and a hydrocarbon test on the cooling system and see what they find.
I have seen several kinds of block sealing systems available. Though I generally do not recommend them, as the longevity of the repair isn't predictable, you could try that as a option of last resort.
There is no quick easy solution to your problem but with a bit of "poking around" you may be able to cure it. Don't bother repairing one problem before finding out what the other one is first though as together, it might be smarter to replace the engine.

Sounds like a leaking head gasket. The coolant could be leaking into a cylinder and is being burned out the exhaust.

Losing water.is there a water drain pipe that comes from the heating system


If you are not seeing a coolant leak on the ground, and you are adding coolant every week, chances are the engine is burning it out the tailpipe. That would be from a leaking head gasket or other internal problem with the engine.

If heater core is leaking coolant will this cause engine to over heat?


Yes it can, the coolant leaks from the heater core, and causes the engine to lose coolant. The sad part is, if your heater core in underneath your dashboard, you will have coolant in the floorboard.

Coolant leak/ squeak/ no heat


The squeak you hear is because coolant is leaking onto the belt making it slip and that is the squeak you hear. The reason your heater isn't working is because the coolant is low enough that it isn't able to circulate through the heater core and heat your car. If you are losing a gallon of coolant a week, I would guess you either have a coolant hose with a leak or your water pump is going bad and starting to leak. It could be getting weak which also would cause you to not have heat. I would get it fixed soon before the pump shells out on you and your engine overheats which could cause more damage to the engine.

Good luck

Thermostat or not?


the coolant lose is possibly causing the no heat problem. the lack of enough coolant to fill the heater core can cause it not to heat the car up. you need to find the leak. what engine you have????
