A/T or MT? its toyota engine, read the wiki.

if A/t THAT CAN BE THE A/T OIL COOLER.

FLUSH THE COOLANT AND DRIVE 5MILES WITH ONLY WATER
Sorry caps on, ok , the oil can not come from the engine.
easy. as there is no easy path (besides cracked head or block)
the oil gallery is to head is only 0.050" yes i mike everything i touch.
you could bypass the oil cooler on the tranny.
you could send the oil in rad, put in med bottle and get it checked
for ATF or Engine oil.
if the A/T ATF is still pink ?then is the water test above pink>??? easy huh>
im sure jiffyboobs didnt to your car too , right?

keep in mind at start up the RAD pressure is 0
and hot 14psi
so the A./T pump can sure has H3LL push fluid to the rad.
and when hot , it can go the other way.
differential pressures.

AF in engine oil is easy with bad head gasket or warped head.
usually the Eng oil dont go to RAD unless real bad. super warped.
if spark tips are not soaked in oil, then good. or green.

the pure water trick will help.
help see color better. and not react with chems in AF.
do not leave water in overnight or day frigid temps or the block will crack.
like this. (not me, Florida bimbos)

I got a 97 geo prizm and its leaking radiator coolant and it's not the holes or the radiator


You need to find what's leaking before you can fix it. We used to pump pressure into the radiator, so we could check for leaks without having to run the engine. Put car up on jack stands, pressurize the radiator, find the leak. Then you know what needs replacing.

Car won't start


old post , no year car, 1989 to 2002
there are 3 engines, 2 up to 1998. all made by toyota
overheating is it,
forget all else. FIND reason for overheating, coolant lost top list.
if loosing coolant that is #1 above all else. find cause.
but
overheating KILLS all ENgines. if not cured fast.
warps heads
is it pinging? that too kills engines.
your engine should never overheat unless it has cooling problems or.

unless the head is warped now, it will overheat, due to coolant loss
is it loosing coolant every hour or day?
CRANKING ALL ENGINES THAT DONT START DRAINS ALL BATTERIES, IT'S NOT a SYMPTOM IT'S NORMAL FOR NOSTARTS. (starter sucks 100 amps from battery every try)


id do a compression test first.
look for coolant in these spots
1: pavement below car.
2: passenger foot wells. (heat core leaks)
3: low radiator at neck cold show no coolant seen there.
4: in the a/t transmission, turns AFT to chocolate milk.
5: water in the engine oil pan, and or the reverse.
oil in the radiator, or side tank.
do all you can to not overheat any engine, and keep the repair bill like 1/3 or less. of BOOM

Does a 1993 geo prizm 1.8L lsi have two temp sensors?


buy the manual. and RTM,
and yes, Air , water, and on a stock car up to 3 coolant sensors.
The ECT runs the ECU. tells ECU coolant temp.
my guess is the coolant gage is dead? RTM
on most 93 car, the Guage has its own sensor, (isolated)

89-02
joint venture, GM/toyota with 3 engine used.
1.8L or 1.6L
toy engine, 4aFE, 7AFE or 4AG
open hood look
or use the GM RPO tag
or Use the VIN to find motor used.
for docs?

How would i know if my overheating problem in my 97 Geo Metro Prizm is a radiator, water pump, blown head gasket, cracked head or a thermostat problem. is there some way i can check for this?


Oil and coolant mixed usually means the engine is damaged.
Blown head gasket, or cracked block - head.
You may have coolant in the engine oil too.
I would not drive it.

Why does my 1994 geo prizm tend to almost overheat wih a/c on?


There are two possiblities that come to mind. Low coolant level with a very big air bubble may not permit proper cooling (too much air in the cooling system so add more liquid) or the second thing could be that the thermostat is not the proper rating for your gauge to remain below the middle level. You should try replacing the thermostat with a 180 degree thermostat (yes again and make sure orientation of the thermostat is correct... not upside down) and if the NEW thermostat is "good" it will stay near the middle regardless of whether the AC is on or not. You should also carefully check for coolant leaks or a reservoir tank crack, a loose fitting radiator cap with a worn o-ring or anything that would keep the system from being pressurized since pressure and glycol are what prevents the water from boiling in the cooling system.

Power streering leak, smoke under hood for 1996 Geo Prizm


Yes , power steering fluid will smoke if it gets on a hot engine, especially on any part of the exhaust system. Barring anything else wrong with the engine such as a coolant leak, and the engine running OK otherwise, I would say that the smoke is from power steering fluid dripping or getting blown on the exhaust by the fan.

Prizm overheats, heater core leaks, no heat


You can bypass the core or fix it that's up to you but I would change or remove the thermostat first. If it still overheats then start looking at the water pump and radiator. Hope this helps. Good luck.

Oil in coolant


Head gasket or cracked head. Thats the only way oil can get in the coolant.
Do a compression test on each cylinder to test for crack or leaking gasket.
