gen 7 What kind of engine is in my '95 Toyota Corolla (Geo Prizm)

While I was out looking for a Metro I ended up deciding to go with a Geo Prizm.


So I brought it in to be evaluated and was told that it has a Toyota engine in it, not the original engine . . . I told him the car is a rebadged Toyota Corolla and he said "I know that . . . but it doesn't have the right parts"

So if this isn't the original engine that goes to this car . . . (and I paid $50 for the reputable repair shop to tell me that) . . . what kind of engine is it?



It's missing sensors for the EG valve or a sensor for it . . . *sight*

Welcome.

It certainly looks like the original engine. There should be a VIN number stamped on the engine below the upper coolant hose, maybe covered by dirt and grease. See if it matches the VIN.

Do you mean the EGR sensor? I don't think there is a temperature sensor for the EGR. The computer checks if the EGR valve is opening based on intake manifold vacuum.

And the spark plug wires are supposed to be rotated 90 so the wires are routed along the back of the valve cover to the distributor.

You're making me think I got ripped off Dr. Z . . . I mean, the thought is unsettling I will grab the paperwork with the full report on it to clarify - some of this may of been lost in translation

What did I write to make you feel you got ripped off? Prisms had he same engines and transmissions as Corollas. Do you want it to be the original engine or a different engine?

Not with the car. I would be happy to have Corolla reliability . . . but with the service I received today - he insisted it was not the original engine. I guess tomorrow morning I will look around for the VIN number on it

Welcome to Toyota Nation and congratulations on the purchase?

I'm curious what parts he thinks are different. Whether it's the original engine or not doesn't matter as much as that it is the correct engine for the car.

Oh, I see, the service. I frequently need things spelled out for me.

Hi, welcome to TN.

Look under bonnet for emissions decal. It will tell you if you've got 4A-FE or 7A-FE engine.


Next, look at the flat part of block just ahead of distributor for engine-model stamp. In this example, it's a 5A-series engine. Yours will say 4A or 7A.


The mechanic may be getting his model years mixed up:

- '93-94 California model, only years that had EGR temp-sensor
- '90-92 1st gen Prizm Gsi model had 4A-GE engine

It wouldn't matter if it was a Toyota engine anyway, as long as the Geo emissions and electrical is used which shouldn't be an issue. The year will dictate the emissions package, the VIN will tell you the original engine. To quickly ID it, the 1.8L has a two piece oil pan, with the lower piece (the part with the drain plug) being entirely on one side of the cross member. The 1.6L has a one piece pan that runs the full length of the block up to the side of the transmission. Off hand it looks correct for a 95 year engine too.

FWIW you can't easily go from a 1.8L to 1.6L with an automatic due to different control systems for the transmission, with the 4spd/1.8 being electronic with everything in one ECU vs the hydraulic/mechanical/vacuum/whatever the 3 speed in the 1.6L is regulated with.... going 1.6L to 1.8L is possible in theory, can't recall if it has been done. So I don't think you really need to worry much about that.

I have a 93 geo prism and it also has a toyota engine. Thats why i bought it. GM and Toyota had a joint venture for a while. Your engine is correct. Find another mechanic. Maybe even ask for your cash back or a free oil change at the least. BTW, good find. i bought mine with 95k on the clock. Now have 300k. did 1 head gasket change and rad. normal maintenance. cv axles brakes, timing belts, etc. Did go through 2 dizzys. These things are bulletproof if you treat them right.

You can also tell the engine by the chassis VIN and then check the engine oil pan to verify 1.6 or 1.8. 1.8 is a two part pan, 1.6 is a single large steel pan.

I wouldn't even take an oil change. Might put domestic oil into a Japanese engine, knowing him.

Side note: I'm joking.

gen 7

I noticed you have an Automatic Transmission dipstick, going from there a very reliable way to find out what engine you have without even opening the hood or going under... check out your shift lever. Does it have a smaller button on the side that says overdrive? If so you have the 7A-FE aka the 1.8 liter. This was the simplest way to find out when customers needed help when I worked at an Auto parts store. It is very unlikely that your engine was downgraded to a 4A-FE at one point in time but this worked best for me

95 Satin Black Corolla DX 4A-GE Blacktop/C160

You're also missing the battery hold down, get that replaced ASAP.
