Car problem - expert help needed

[The Sauce]

Hey, I have an '88 Supra. Ihave been having thermostat troubles and just noticed that there is a line that seems to be broken off from the thermostat and is just sort of dangling there. Toyota told me that it was a vacuum line and that it shouldn 't be a problem but they were not able to tell me exactly what it's purpose was. Anyone know anything about this?

 

[BaseballSTUD]

they are more than likely right that it is vaccuum and not a big deal...the thing you want to look at is the thermostat itself has seized up and needs to be replaced...what exactly does the car do (concerning the thermostat)?

Have you looked at a Haynes maual or seen an exploded view of the area? Go to the dealership and see if they'll print you a diagram (off Microfische or DVD) or just get a repair manual (Haynes/Clymer).

It's a vaccum line that runs from the temp/vacuum switch, this either controls the emissions equipment and or sends a vacuum signal to control ignition advance, replace the vacuum switch.

Don't worry about the vacuum line. Maximas have that hose dangling too.

Go back to what you do best, sitting on the sofa watching Opra.

uh?

 

It is very obvious that you don't know jack squat about automobiles, that comment was a derogatory remark regarding your statement.

Any vacuum line dangling is not good. I would get it looked at and fixed ASAP, as most likely the mechanic who worked on the car previously might have either forgot to re-attached the line, or left it out on purpose to mask a bigger problem. Or the hose could be so old that it fell off.

Anyhoo, get it fixed fast!

hmmm you are right. The hose dangling in the Maxima is a breather hose....

Yeah, you don't wanna piss off a vacuum hose. Think of it this way: you're sitting there, happily sucking on a nipple when *wham* some assmuncher pulls you off your delightfull perch and leaves you dangling. I'd be pissed too!

No it isn't, it's the coolant hose.

I'm talking about the hose is located near the large breather hose on the front valve cover.

I have an '87 Supra Turbo, but haven't noticed any dangling vacuum hoses. Good luck, listen to Roger.

What's a valve cover?

 

[BooneRebel]

No, it's the gas hose. Forgot to pull that thing out at the last fillup.

 

[Pepsi90919]

find where the hose goes and connect it.

 

[Zenmervolt]

One more person saying to listen to Roger. Disconnected vacuum lines are not good, their will either be sub-optimal FI performance/drivability or the hose is disconnected in order to mask something larger. It's absolutely amazing how many big problems can be masked by messing with the vacuum lines.

I'm no car expert but I say get the hose fixed. It shouldn't just be dangling there.

Roger is teh man when it comes to fixing cars!!

As always, Roger has the well-respected opinion. The problems I am having right now are a thermostat gague that is jumping back and forth from warm to cold, a heater that takes a long time to start working, and a very high idling engine (when cold, up to 2400 RPM). Could any of these be accounted for by the vacuum line problem? That was what I brought it to Toyota for but they said leave it alone.

Have the hose reattached, and put a new thermostat in.

Listen carefully, how fast is the temp gauge jumping back and forth ?
Is it jumping to hot and then cold within a ten second period ?

The long heat up times (Interior heat) results from either a bad thermostat, low coolant or a blown head gasket.
As for the vacuum line problem, carefully look under the hood for a vacuum diagram, if you cannot find one, go out and purchase a Haynes repair manual, this will contain the vacuum diagram that is needed for proper re-installation.

Yes, a disconnected vacuum line can cause a high cold idle speed, it can also cause misfire, poor fuel mileage and rapid engine wear.

Go to another Toyota dealer, apparently the one you went to does not have the qualified personal to properly diagnose your problem.

What exactly do you mean by jumping? Does the needle literally flick from cold, to hot? Or is it a gradual increase, within a 10 second range, as Roger stated?

My girlfriends' mom's Toyota Camry would do that. We never did find the problem.. I always figured there was just a short somewhere... lol

 

[Ornery]

Wouldn't there be two vacuum connections on there? One for vacuum coming in, the other to pass the vacuum to another component? In other words, a temperature controlled vacuum switch.
