Can you use Bars radiator stop leak in a 2002 BMW 325 I?

possible a tiny pin ***** will end up under presure leeking like a good one but i would also check the radiator as well as the same thing could happen to that can you tell where it is comming out from is it one the engine or radiator etc

If your heater core is leaking that it a good sign that it is your problem. When the heater core gets plugged up it has a tenancy to leak. The water can not flow through freely and causes it to leak.

TO FIX COOLANT LEAK.YOU HAVE TO LOCATE IT.BEST TIME FIND COOLANT LEAK WAIT UNTIL MORNING.ADD COOLANT UNTIL COOLANT LEVEL IN RADIATOR CORRECT. START THE ENGINE LET IDLE UNTIL START GETTING HOT.THEN TURN OFF ENGINE.COOLANT PRESSURE WILL PUSH COOLANT OUT WHERE LEAKS ARE.CHECK TOP RADIATOR HOSE AND BOTTOM RADIATOR HOSE.CHECK AROUND RADIATOR LOOK DOWN BELOW COOLANT FAN AREA BEHIND RADIATOR.LOOK FOR LEAKS AT RADIATOR CORES AND SIDE CONTAINERS.CHECK FOR COOLANT LEAKS AROUND WATER PUMP GASKET OR WEEP HOLE.CHECK FOR COOLANT LEAKS AROUND HEATER HOSES AND HEATER CORE.CHECK ENGINE CRANKCASE FOR COOLANT LEAKS.

Try "Iron tight" head gasket sealer.

it is time to replace it...radiators are expensive at parts house....i would replace it with one from a wrecking yard or from craigslist.com...you really don't need that stop leak screwing up your cooling/heating system...hope this helps

the dealer parts dept usually has the best exploded diagrams

No, this is a dealer trying to get out of replacing an engine. I would talk to a lawyer and have them call the dealership. Stop leak VERY rarely clogs and I have never heard of an engine hurt by today's radiator stop leak. Maybe back when they put black pepper in the radiators to stop leaks that would happen but not now. PLUS BMW's have such great cooling systems that it would never happen.

well its a bmw......... that could be the problem

The check engine light could be any number of things and the only way to find out is have the codes scanned. The brake light issue is common on E46 3 series. It is an issue were the brown ground wire that goes into the lamp housing melts at the connector causing a loose ground connection. The connector needs to be replaced and also add additional grounding wires to prevent further issues. And for fuel additives either use the cheveron techron, or the bmw fuel additive(the bmw stuff is the exact same thing, so just use which ever is cheaper).

It needs a new fan control. $80 online and 20min. labor. I just replaced mine in the same car.
