The gasket suface problably was not clean enough and or did you use sealant? Sometimes the thermostat does not sit in the housing properly, since the housung is bolted to the head on its side, good chace the thermostat slid a little bit..
Let me tell basically the places it could be leaking. If it inside the car then the heater core is probably bad. Check the radiator, the top, and bottom coolant hoses. The bottom hose will coming from your water pump. The hoses or the water pump could be leaking (if the pump is leaking then it will have to be replaced). There is a thermostat that could leak if not properly installed. This will be located, under a housing, at the point your top hose enters the engine. There will also be two hoses going toward the fire wall. These are the in and out hoses for the heater core. Theses could also be leaking. You could always get a UV light kit and put dye in the coolant and trace it that way also. (This in my opinion is the easiest method.) Well, I hope you find it. Good luck.
I would check the hoses leading into your radiator, and also the overflow for antifreeze. If that is not the problem, it could be your heater core. Your heater core might be leaking, you might have a hose leaking
no, check the coolant reservoir 1st, if its full then after car is at operating temp. look underneath and see if any coolant or water is on the ground below the water pump if so the weep hole is probably leaking on the water pump check the componet if all check out it maybe the thermostat fairly enxpensive to replace so i would replace the thermostat and check the temp again but if the water pump is leaking it needs to be replaced
Has the rad ever been flushed? Try that if there is no indication of water pump failure (leaking or venting coolant from pump.)
Check the water pump. Examine it for traces of dried coolant that might be leaking out of the casting.
only if the gasket under thermostat is leaking and may-be it's the hose clamp on the hose that is leaking
There are all sorts of places that coolant can be leaking from. You just have to look until you locate it.
Yes, this sounds like coolant from a cooling system that has been neglected and not flushed and changed regularly. Have the leak fixed, a new thermostat installed, a fresh mix of 50/50 coolant installed, and bleed the system.
try taking out the thermostat and have you put to much oil and coolant in the radiator
A faulty thermostat in a 2001 BMW 325CI can cause a coolant leak. The coolant may be leaking out a crack in the thermostat or through a warped edge. In some cases the problem may be just a bad gasket and not actually a problem with the thermostat at all.
It could be a number of things, a clogged radiator,bad thermostat,low coolant, hoses leaking coolant, radiator fan not working,or a leaking head gasket. Hope this helps you.
That is coolant leaking.
If it is leaking coolant. And you changed the thermostat. I would then move to this section. Flush the radiator and the heater core. This can be done at a certified shop with a reliable mechanic.
If you have coolant on the top of the engine it could be a leaky thermostat housing or a leaking intake gasket.
Bad thermostat, Low on engine coolant--( coolant leak ) Cracked head, Leaking head gasket,
Freeze plugs. More likely that hoses are leaking or thermostat housing is leaking. Freeze Plugs generally NEVER leaks unless engine block has had frozen coolant in it. Hence, Freeze Plugs.
