Can you put a stop leak in coolant to fix a leaky heater core in a 2000 blazer?

Yes you can but that is a temporary fix. Some stop leak brands do more damage than good by plugging up everything else like the radiator for example. I recommend "Barr's" brand stop leak if you are going to use one.


What is wrong with your 1999 Honda Accord you always put Coolant every week?

You have a leak. If you cannot see any external leak anywhere, then it is internal. That would mean you have a blown head gasket. If so that is very serious, and severe engine damage will occur if you continue to drive this vehicle. STOP driving this car until you have this repaired.


Will stop leak help your minor coolant leak from lower intake gasket 3.1?

Try Bars Stop Leak; its` worked wonders for some, none for others. Worth a shot though.


Where could a leak be coming from the engine coolant?

If you can see no external leak, then suspect an internal leak as in a Blown Head Gasket. This is very serious and severe engine damage will occur if you continue to drive the car. Get this repaired ASAP, and stop driving the car. You do not let us know if you see coolant on the ground or on the engine. It's hard to diagnose with out a little more info.


Small coolant leak and you have the stop leak to fix it would you pour that in the resivour tank where the coolant goes?

How do you clear the instrument panel light for coolant reservoir?

Check the coolant reservior for any leak. 1. If there is leak, try to stop the leak by A). go for coolant reservior replacement from dealership or from junk yard used part dealer. B). Stop the leak by putting adequate glue (i.e. glue which could sustain high temp) over the leak area. 2. If there is NO leak, it is probably a bad sensor, a known problem according to the Mazda Parts Dept. Replace the reservoir which includes the coolant sensor. They are sold as one part.


What is happening when engine coolant disappears from container?

Either you have a leak at the reservoir, or someplace else in your cooling system. You may also have a bad water pump that is leaking.

Why is your 2001 Ford Explorer burning antifreeze?

Anytime coolant is entering the combustion chamber it is an indication that you have either a blown head gasket or a cracked head. Symptoms are white smoke from the exhaust, loosing coolant with no apparent leak, oil level increasing, & white foam on the underside of the oil cap. STOP driving the vehicle immediately. Serious engine damage will occur if you do not have this repaired immediately.


What do you do if coolant is leaking coolant your 95 MX 6 V6?

Find where it is leaking, and repair the leak, adding "Stop-leak" will possibly work, but may create more problems by doing so. If you can't find the leak, take it in for repair.


What happens when your car runs on a blown head gasket on a Honda oddysey 1996?

Coolant will enter the combustion chamber. This will cause serious engine damage. Your Catalitic converter & O2 Sensors will also be ruined. STOP driving this vehicle until you have this repaired.


Will a stop leak fix a antifreeze leak by the intake manifold?

NO additives are recommended by any good mechanics. Only the full repair is best especially whem dealing with coolant leaks. Usually intake leaks are from years of corrosion the coolant will turn to acid in most oif todays cars if not treated you will have much internal damage. the external leaks will only show up when damage is done. Dont write off the vehicle it ,will be much cheaper to repair than pay the extra cost for insurance ,interest loss of value for new cars.....


Should you leave stop leak in cooling system after the leak has been repaired or drain and refill radiator with fresh coolant?

Drain, flush, and refill.
