SV21 Camry with 3S-FE: Coolant Air Bleed Screw Location

[coolozzieguy]

Hi All,

New to Toyomods, but am helping out a friend with a big service on his wife’s neglected 1989 build SV21 with a 3S-FE. I will be doing all the usuals, like plugs, leads, filters, etc. but it's also in desperate need of a coolant change. I have done plenty of coolant changes in the past, dad is a mechanic and has specially designed funnel with radiator cap on the bottom to help give coolant a high and hopefully air-free entry into the engine, and it works a treat. It is the yellow one pictured below:

But my question is:
I have searched online and using the search here, and can't seem to locate an air bleed screw\fitting on the 3S-FE. I haven’t had a good look at the engine in a while, but I know some late 80's- late 90's Jap engines have bleed screws at the top-most flow locations to assist with getting trapped air out. Obviously the heater will be open and I will be using the elevated funnel with radiator cap, and squeezing rad hoses and so forth, but if anyone can show me a pic of the location of the bleed screw (if it in fact has one) I would be very grateful. I have looked at some photos of the engine and noted there is a screw-in coolant temp sensor or coolant gauge sensor on the thermostat, but am unsure if this is it.

Hope my first post is descriptive enough

Thanks.

Not all engine have them, mine doesn't.

Infact the only car that ive owned that did have one was a slivia.

The rad cap will be the highest point, there arent any bleed points. There is a drain on the back of the block but thats it.

No worries, I just like to be thorough. My old N13 Pulsar, for example, had a bleed screw on top of the thermostat housing, which doubled as the sender for the temp gauge.

Just wanted to see, have been working on mainly E-series and A-series falcons as of late and wanted another opinion.

Thanks for the replies, wish me luck.

nearly all toyotas dont have bleed screws,you remove the hose from the heater tap and fill the system until coolant runs out of the hose and the tap,this applies to almost all toyotas,when there is no bubbles coming out you refit the hose.job done

^ ^ as above.

I think a lot of 80s/early 90s nissans had them, but no toyotas I'm aware of

Toyota actually designed their systems properly, with the radiator cap as the highest point in the system, unlike some others *cough*RB30*cough*

Lol... indeed. Although I am led to believe from some of my nissan mates that this was only an issue with the VL DumbyDore, but dunno about the Skylines.

Did the job on Saturday as planned, used the coolant fill funnel, and all the bubbles seemed to pop out. Although it did take a big burp when the thermo fans kicked in, I guess they have a later than I am used to opening thermostat, but all seemed ok. Went for a couple of test drives, and the car hasn't overheated or had temperature spikes up or down all week.

But WOW! How good are those thermo fans! Toyota seem to engineer things pretty well for our conditions.

Thanks again for the advice.
