Hello new here =)

Have a Corolla KE30 -77 with a 3KC engine and i dont find any info which type of coolant that is recommended, ethylene or propylene?

Make my day..

due to the age, i'd guess ethylene glycol coolant.

Yes I guess that to but i want some facts =) Isn't there some page on the internet with old Toyota specifications? Even the Toyota dealer wasn't sure about it and unfortunately i didn't get the manual when I bought the car.

Thanks

Ethylene is toxic. propylene is less toxic and used where the possiblity of injestion can occur.

Toyota recommends a coolant that is silicate and borate free.

The article belows explains some differances between coolants:

Yes I am aware of ethylene and propylene basic knowledge but this car have had one or the other for 30 years, not both. I don't wanna change that =)
