Location of Coolant drain plug on engine 4A-FE Corolla

Please describe the engine code for example 4A-FE, 3ZZ-FE and so on. For your convenience the timing chain installation for Corolla 3ZZ-FE is described below:

its not A/C Freon, its called AF, antifreeze coolant, and
all leaks end in , overheating (be patient) and engine destruction(if patient)
how far can you go with an artery cut.>? same deal.
all I have for evidence here, (im blind in this box) is that the cap leak
so buy a new cap, if that dont fix it , it means.
1: ENGINE IS overheating, over 250F,
2: or the engine has a bad head gasket or cracked head or block.
3: or bad water pump (impeller 1/2 gone from neglect)
4: or cores in Rad, some blocked, (neglect)
5: loose fan belt.
5: wow, system not fULL? not kept full of AF at all times????
and more.

the car and engine are 100 % Toyota Corolla.
7a or 4a engines. not stated. here.
these

• 1.6 L 4A-FE (L01) I4
• 1.6 L 4A-GE (LW0) DOHC I4

which one?

wow, no year stated now that is a challenge. no?
what makes you think there is one.?
there are 2 gas engine, air flow systems.
one uses a MAF
one uses MAP
IN 2014 CARS now have both and are adaptive.

is this the 4a or 7a engine , the IS a toyota Corolla. in snakes clothing.

• 1.6 L 4A-FE (L01) I4
• 1.6 L 4A-GE (LW0) DOHC I4

1.8 L 7A-FE (LV6) I4 (gasoline)
1.8 L 1ZZ-FE (LV6) I4 (gasoline) wow 4 engines

if in USA< are you?, canada.?
USA:
open hood see EPA sticker under hood; look up.
see that?
it tells you which engine you had day 1. and year car actual too.

we can not fix (unknown engines. )

Vehicles covered: Toyota Corolla, 4A-F, 4A-FE, and 4A-GE Engines

Here's your maintenance manual entry for the complete procedure:

OIL PAN REMOVAL & INSTALLATION - 1990 Toyota Corolla

8. On the 4A-F and 4A-FE engines, remove the center mounting.






Fig. 4: Remove the bolts and nuts retaining the center mounting-4A-F engine

9. Some 4A-FE engines and all 4A-GE engines are equipped with a stiffener plate. Remove the set bolts and pull the stiffener plate from the vehicle.

10. On the 4A-GE engines, unbolt and lower the flywheel housing under cover.

11. If equipped, remove the oil cooler hose and union from the oil pan. Remove the two nuts and nineteen bolts retaining the oil pan.

12. Insert a blade between the pan and cylinder block, cut off the applied sealer and remove the pan.







Fig. 5: Insert a blade and tap lightly to loosen the oil pan free from the block

To install:

Note: Be careful not to drop any oil on the contact surfaces of the pan and block.

13. Using a razor blade and gasket scraper, remove all traces of packing (FIPG) material from the gasket surfaces. Thoroughly clean all main surfaces to remove loose material. Clean both sealing surfaces with non-residue solvent.





Fig. 6: Apply a reasonable amount of sealant (FIPG) to the oil pan surface-except 7A-FE engine

14. Apply new packing (FIPG) 08826-00080 to the oil pan as shown. Avoid applying excessive amounts to the surface. Be especially careful around the oil passages.

Note: Parts must be assembled within 3 mins of application. Otherwise, the sealer (FIPG) must be removed and reapplied.

15. Install the oil pan over the studs on the block with the nineteen bolts and two nuts. Tighten the bolts to 43 inch lbs. (5 Nm). Make sure when you install the oil pan drain plug using a new gasket.






Fig. 7: Tighten the 19 oil pan retaining bolts securely-4A-F, 4A-FE and 4A-GE engines

16. If equipped, install the oil cooler pipe, two new gaskets and union bolt. Tighten the union bolt to 18 ft. lbs. (25 Nm).

17. Install the front exhaust pipe (with new gaskets on either end of the pipe) to the manifold.

18. On the 4A-GE engines, install and secure the flywheel housing under cover if removed.

19. On the 4A-FE engines if removed, attach the stiffener plate. tighten the No. 1 bolt first then the 5 bolts in the sequence shown. Tighten to 17 ft. lbs. (23 Nm).

20. On the 4A-GE engines, attach the stiffener plate with the 3 set bolts and tighten them to 27 ft. lbs. (37 Nm).

21. Attach the center mounting and tighten the member side bolts to 38 ft. lbs. (52 Nm), plate side to 17 ft. lbs. (23 Nm).

22. Lower the jack from the transaxle.

23. Lower the vehicle, and fill the crankcase with the appropriate amount of engine oil. Engine oil crankcase capacity is 3.4 quarts (with oil filter change).
Above -9 degrees Fahrenheit, use 10W-40 motor oil, and above 10 degrees Fahrenheit, use 20W-50 motor oil.

24. Connect the negative battery cable, start the engine and check for leaks. If all is well, raise the vehicle slightly and install the engine splash cover.

25. Recheck the engine oil level, top off if necessary.

Keep in mind that tTe thermostat is installed on the inlet side of the water pump. Its purpose is to prevent overheating of the coolant by controlling the flow into the engine from the radiator.

Hope this helps; also keep in mind that your feedback is important and I'll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using Fixya, and have a nice day.

You can check to see which engine you have by looking at the number stamped vertically into the block, just to the right of the exhaust manifold. If you can't see it, give it a wipe with a cloth and use a torch to see what it says. If you've got the 1.6L 4A-FE it will say 4A and if you've got the 1.8L 7A-FE it will say 7A. Take a look at photo.

Corollas made from 1993 to 1997 had two engine choices, the 1.6 liter 4A-FE and the 1.8 liter 7A-FE (click here for many details, comparisons, and diagrams).

Fig. 2: Firing order- 4A-C engine (other A-series similar)

Look on the cross rail that is under the radiator- there are several holes in it, one, closer to the driver side provides access to the drain plug. Use a flashlight to see it easier. Than just use a long flathead screw driver to unscrew it, make sure you dont loose the rubber washer (it may stay in the drain opening). Also make sure you have a wide drain can, as the coolant will get into the cross rail and drain through all the holes

Hope helped.

The thermostat is located in the water inlet housing that is connected to the lower radiator hose.
The thermostat is equipped with a by-pass valve. If the engine tends to overheat, removal of the thermostat would cause a decrease in cooling system efficiency.

CAUTION NEVER drain coolant directly onto the ground! NEVER open, service or drain the radiator or cooling system when hot; serious burns can occur from the steam and hot coolant. Also, when draining engine coolant, keep in mind that cats and dogs are attracted to ethylene glycol antifreeze and could drink any that is left in an uncovered container or in puddles on the ground. This will prove fatal in sufficient quantities. Always drain coolant into a sealable container. Coolant should be reused unless it is contaminated or is several years old.


Fig. The oil filter must be removed to access the thermostat on the 5S-FE engine

1. Position a suitable drain pan under the radiator drain **** and drain the cooling system.
2. On the 7A-FE engine disconnect the engine coolant temperature switch harness from the water inlet housing.

Fig. Disconnect the engine coolant temperature switch wiring located on the side of the thermostat housing

1. Remove the oil filter on 5S-FE engines.
2. Loosen the hose clamp and disconnect the lower radiator hose from the water inlet housing.

I hope help you with this (remember rated this help) Good luck.

An engine from another Corolla up to 1997 will fit. There are 2 engines though. 4A-fe (1.6L) or a 7A-fe (1.8L) They look similar but run different Engine managment computers. The 4A-fe uses a 3spd auto trans and the 7A-fe uses a 4spd auto trans. Also some of the wiring may be different.
Hope this helps.
