Hey guys last question of the day! Does Toyota use a standard hoses size for all the heater hoses, I'm trying to switch colors and since samco doesn't make a kit I gotta do it myself! Found awesome hoses but curious since the offer like 6 different sizes! Thanks alot guys

 

Most Toyota heater hoses on the firewall have custom bends that might be hard to duplicate without kinking.

:wabbit2:

 

Yeah I'm using wire reinforced hosing, plus I'm not interested in doing every single one, just some annoying black ones on top! My brother works on Volvos and im actually running 3 Volvo hoses under the hood. Got about 20,000 on them and no issues lmao, actually rated better then Toyota hoses! So does anyone know? Or I gotta get back there and measure the circumference of the hose and use my math skills which suck!

 

Just use your math skills and post what you find here.

 

Lol I'm working on it, there only about 8 hoses back there I can tell. Seems like 2 different sizes...working out numbers now!
