I have replaced the radiator, water pump. But still loosing coolant. I think it comming out the overflow because of the marks on the hood flung by alternator.
The temp runs between 3/8 to just over half in city traffic. The LIM gasket was changed before I got it.
The stock waterpump had a huge impeller, The after market has alot smaller impeller?
At what temp should the fan come on ?
Fans come on at 223 degrees, probably go off 208 to 212. You replaced the radiator and water pump because they were actually leaking or are you throwing parts at it? If you're getting fresh spray off the belt, what makes you think it's the overflow tank? You can see this engine, we can't, so you need to hose off the front of the engine to rinse away existing coolant and see if you can locate the source then. The LIM gasket was done how long ago and with what brand of gasket? New water pump. Remember new doesn't mean good. It isn't a remanufactured pump is it? The rear cylinder head gasket has a habit of leaking right at the corner under the alternator and is sometimes mistaken for a LIM gasket leak. So, head gasket, LIM gasket, water pump, water pump bypass pipe, lower rad hose with a pin hole that sprays the belt, probably more, just a quick list.
Answering MK's question, radiator cap is on the overflow bottle. If the overflow bottle is leaking you should be able to see it fairly easy. Probably I'd rinse the engine down ,let it air dry and start the engine, let it run and keep watching.
Dumb question, but MK has a point, is the coolant level dropping? If it just dropped once or twice after filling the system, then stabilizes and doesn't drop anymore, you may have worked air out of the system. Good luck.
