I have a 1994 Toyota previa. It failed emmissions
My 1996 has had the P040 code (EGR insufficient flow) for years and years. I suspect the EGR modulator has failed, but have not had to fix it, because it drives just fine and I don't live in a place that needs emissions testing. My Chilton's manual has details how to test the whole EGR system and each component. I recommend buying a manual and going through the testing systematically rather than trying new parts randomly. The manual is usually around $20 at any autoparts store (or ebay).

Loud noise from rear
My 96 low rumble was caused by the U joints on the drive shaft. The front drive shaft starts near the rear of the vehicle, transfer case. The U joints are non-replaceable, so I had to buy a new one from Toyota. The parts guy said it was the only one they could find in the US. Around $650. Alternative was to ship the drive shaft to an outfit in Texas that cuts of the old U joints and welds on replaceable types, cost around $500. I changed the center drive shaft support bearing too. No more rumble.

How to replace thermost 1994 Toyota estema
In the USA the Estima is called Previa, and there may be some differences, depending on whether it has the 2.4L or a 2.2L engine or other options.
Labor Time for this job is One hour.
The water pump on the 2.4 Liter engine is accessed under the vehicle, very likely the same on any engine for these models.
Follow the radiator hoses to the engine until you find the water pump, which is near one of the drive axles.
The thermostat is bolted to the water pump with two bolts.
Drain the cooling system, then using a large pan under to catch any extra coolant when removing the thermostat housing.
Carefully clean the surfaces of both the thermostat housing and the water pump. [Check water pump for coolant seepage, which leaves a crusty beige or pink deposit. If so, replace the water pump.]
Install a new thermostat and gasket (Or O-ring).
Refill the coolant with the same coolant only if it looks clean.
I would also test the coolant to see what the PH is, which needs to be about 7.2 PH. (Coolant will turn acid over time, even when it looks okay.)
Make sure you put as much coolant back into the system as you removed.
Fully warm up the engine, and let it cool down before removing the radiator cap, then check for air in the system, topping up as needed.
The radiator needs to be full to the top.
Also check the overflow reservoir, which has level marks of Low and High, Never fill over the High mark.

Water coming out exhaust
If you are losing coolant out the exhaust, the exhaust will have a sickly sweet smell as opposed to the normal stench. Otherwise, a small amount a water dripping from an exhaust pipe is not unusual, as moisture from condensation can build up inside the muffler when driving short trips; this moisture is expelled while driving. If you are not losing coolant, then this is probably what you are seeing and it is not a problem.

There is water coming out of the exhaust of my
most cars I work on drip out the exhaust on the floor alittle when we jack up the front end-Ithink this could be condensation-but if you have white smoke and a sweet smell with it -it could be antifreeze leaking into combustion and going out the exhaust-hopefully not-cheers Denny

1994 Toyota Previa is overheating
- Check the radiator cap for proper sealing.
- Blow air from outside and inside of the radiator to clean the fine dust accumulated in the feathers and fins.
- Check the radiator for clogged inside. Clean the radiator after disassembling it.
- Check the water pump belt for looseness or wear.
- Check the thermostat valve.
- Check the cylinder head gasket or re-torque the cylinder head bolts.
