Cole Austin:
I very much do have the same symtoms you do... But it seems to me that you do have a BHG... I may be lying... after warm-up try smell the exhaust, kinda like a stinky steam smell with a lil bit of fuel on the side... a few of my friends say its the head gasket... it also can be a cracked or a really warped head...
But lets just hope not =T Check your oil dipstick to see if you have any milky spots on it.... if so coolant is going into your block... Or try driving over a dry spot blast your heater and rev your engine to 4k-5k(no more than a min) turn off the car then look underneath to see if you see any wet spots (which you probably have done) (leaky hose(s)) yah and check your carpet for water puddles (leaky heater core\heater core hoses). Try flushing your block and radiator with a water hose while blasting your heater...
My symtoms:
1. Temp gauge goes up
2. Heater blows cold air
3. Drops back down to normal
4. Heater blows hot-hot air (10-20 min)
4. Repeats while local driving... (fine on the highway)
I do have heavy white smoke while idling
I dont lose coolant...
I dont have that milky looking oil dip stick
The coolant color is green, but i do see like oily white spots if you look carefully...
My fan goes on when its on 'H' but the needle doesnt drop until i drive...
Somestimes i have to floor it just to get it back to normal temp...(i just love the sound of the intake WAAAAAAAAAH!)
To me it just seems like the coolant circulation is not really circulating well or something...
What i replaced:
Radiator
Waterpump
Thermostat (170 degree)
Radiator Cap
What im going to replace:
Fan Switch sensor
Head gaskets
Radiator and block flush
Speed sensor
If it still doesnt fix my cooling problems, im gonna change out my heater valve (which im trying to order now).
Maybe i should change out the radiator hoses too?
BTW - Is the ECT (Engine Coolant Temp sensor) the same as the Coolant temp sender?
If not does the ECT effect the way the car cools? I know it effects the fuel flow or something like that...
