OVER HEATING HAS
Many causes, not 2 like in your post over 10
and many symptoms not just 1. in most cases.
its not a gasket,
what makes you think its overheating
1: steam? go that?
2: engine power loss and ping.?
3: gauge told you ? in cluster, some lie , is yours fibbing (tests)
4: water blasting out the side fail tank (expansion tank>?)
5: leaks to ground>?
6: leaks to passengers toes, heater core or its hoses there leaking.
7: over heats only parked, ??????????????
8: fan dead. (that newspaper trick not a real test) many fans are RPM operated, not simple heat locked, as you think. we use RPM optical meter to test fans.
causes.: lots.
A: thermostat bad, they last about 6-7 years and die all do.
B; RAD cores blocked, we use a $15 IR thermal gun aimed at all tubes top/bottom, and find dead tube with no effort at all.
C: pump bad, no its ok , its new.
D; fan belt slips.
E: fan dead, but would not over heat moving fast. so....
F: junk and crud packing a/c front of RAD, condenser, or RAD.
G:engine block full of MUD, from zero service and flushes in 20 long year.
H: cam belt slipped now timing way off, and huge heat load from poorly burning fuel (and late)hits cylinders walls, x4 and huge heat load on the water jackets and with 1 weak item above, pushes said camel off the cliff, is sparking timing right if not cam slipped a 1minute test with any timing light every made.
and more, lots more,
not running 50% AF?
running pure water> omg
I'm a 1994 Isuzu pickup 2.3 liter. Smoke coming out tailpipe overheating severely water is going out the bottom from the Overflow the capitol pop off the overflow when it gets too hot. Change the water pump seem to help some of the water coming out the tailpipe. Take out thermostat to see if that would help it not overheat so I can get out of middle of nowhere. Change the upper hose the demi gauge Rises to hot the heater does hit up you drive about seven miles at the most the dummy sweat the dummy gauge goes down the heater goes cold. Extremely rough startups. Using a tremendous amount of gas. It is a standard five on the floor. It's a small Isuzu pickup. Please feel free to maybe suggest what it could be. If I noticed other symptoms I will post thank you very much
white or back smoke?
please"details matter"
I will guess, now, it's white and is steam. (that never ends)
steam from(water-coolant of engine)
steam goes away fast like a tea pot does.
but oil burning smoke white? takes a long time to disperse,and smells like burnt oil.
steam smells sweet, and is toxic.
antifreeze is toxic, so short sniffs, grin!
#1 steam cause is:
a blown head gasket + I bet head is warped. (true cause)
that steam at rear tail pipe, tells you bad head gasket. (or far worse)
but overheating is serious
why not get a shop to fix it.
if you delay damage cascades
$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$
get a radiator leak down test.
if it fails, engine has servos problems
