    after adding more water to it and driving it around, it didn't over heat but i noticed water dripping quickly out from my exhaust when I got out

  • kmathews88 Feb 23, 2012

    i thought it was a head gasket but my oil isn't milky looking nor is white smoke coming out of my exhaust

    It is the exception not the rule that oil gets milky from coolant in it from a leaking head gasket. Sorry to burst your bubble..

You have a leaking engine cylinder head gasket, this may be due to the previous overheat or a result of it, make sure when you have the engine repaired you find out if the cooling system is in good condition or the problem will recur.

SOURCE: blown head gasket

That would be a lot to type out on the computer.
My best advise would be to get a Chilton Manual at the autoparts store. It cost about $20. You'll get all the info you need plus pictures and diagrams. The Chilton book will be the best research material for the type of job you are going to do.

SOURCE: HI, WHAT ARE THE SYMPTOMS WHEN THE WATER PUMP

you didn't mention if your cooling fan is working check that.
also when a water pump fails you can usually see coolant coming from the weep hole. are you losing any coolant? if so it's either external which could be a loose or damaged hose or connection.
an internal coolant loss couild be a cracked or warped cylinder head or a bad head gasket.
check your oil to see if it looks like a milkshake when you pull the dipstick.
if you have run it hot for a period of time say long enough to limp it home and the temp got very hot then you could be looking at a cracked head or maybe even a cracked cylinder bore.
i hope your oil looks like oil and not a milkshake .

2003 nissan sentra is blowing cold air i changed thermostat stillblowing cold air i did notice that heater core hoses are both cold car is not overheating


remove both hoses from engine that passes through firewall to heater. put a stiff piece of wire in the hole and make sure it is clear. If there is no restriction, then the heater is choked up

1996 Honda Passport overheated. Heater started only hot air when moving, then would go cold at stops two days ago. When it overheated today, a lot of steam came out of the radiator cap. I noticed the...


Ususally when the heater blows hot air only when the car is at hight RPM is because low coolant in the system. It sounds like a bad thermostat . In the worst case you need to do a diagnostic check to the head gasket. Because the first thing to get blowen out when the car over heat are the head gasket.

Nissan Sentra 2001 - Overheating but no hot air


It could be just air in the system, or it could be the heater matrix just by your feet, fitted central dash, check to see if the two water pipes that go into the car from the engine compartment are hot if there is only one that is then thats your problem, but if they are both cold the problem is more to do with where the water is coming from, please let me know how you get on

Heater blowing cold air


My 2005 Nissan Sentra 1.8s with 55,000 mi. blows cold air from the heater. Coolant not circulating in engine. Lower hose stays cool to touch. Both heater hoses cold. Changed thermostat - didn't fix it. Coolant not leaking or dirty. None in oil - no oil in radiator. Changed worn water pump belt - pump spins freely with no noise or resistance. Cooling fans come on after warm-up. Temperature gauge stays in normal range then jumps to hot and back again. Coolant good to 10 below - didn't freeze here yet. No other problems or repairs to car. Afraid to drive and make worse. Help!
