Looking for some good old timer knowledge. It’s past time to replace the vacuum hoses on my 94 Camry 2.2L. What sizes should I get and how much?
The goal is to remove and clean the IAC but the hoses on the IAC and throttle body won’t survive the bending and twisting required. If I’m going this far, I might as well replace all the vacuum hoses, and maybe the coolant lines there too. I’m sure someone here has fiddled with several of these before and knows just what to get.
Thanks, friends.
This is easy. You do just like I did when I needed some new hoses. I took a small section of each hose to the parts store and they matched it up with the hoses they had .
That’s a great idea. I wish I could. When I tried removing one over the weekend it crumbled into tiny pieces. Another had no grip on the metal tube it was attached to. Thus my question. I don’t seem to have a reliable source size.
If I don’t have data by this weekend I’ll buy some samples and see what fits. It was my hope to avoid that route.
Thanks, Volvo!
Go the ‘buy samples’ route - that way you will be sure.
Measure the nipple that the hose slips onto. Not the bulged part, the smaller diameter. Use a caliper or micrometer. If you don’t own one of those, a small open end wrench will tell you. Test fit 4,5,6,or 8 mm wrenches on the fitting. Hose is sold by inside diameter so buy according to what fits. Might want to measure it in English sizes, too, if that’s what you are offered.
I just did a Google search and the result was the vacuum hose is 3.5 mm inner diameter and 7 mm outer . No claim of that being all of the hoses but it is a way to start .
My Corolla of similar vintages uses unique vacuum hoses, sort of a hard plastic, rather than soft rubber, seem to be virtually indestructible and never work themselves loose or leak. Suggest to buy replacement hoses from a Toyota dealership or from someone who sells same exact product. As posted by @Mustangman above, these sorts of hoses are identified by their inner diameter.
