It has been a long two weeks, today I just changed my radiator because I swear it was causing me problems, changed the hoses, car still over heats, so I changed out the Thermostat, the gasket looked really bad and I thought this would fix it all. I just tested it out for 2 miles and the car over heats, and I noticed steam coming out from under the distributor cap. I pulled on the hose that seems really long and then I realized that coolant was coming out of it and this is why the car was steaming and over heating.

What is this hose called? and what is the best way to change it? It looks like I need to remove the distributor cap probably.





THANK YOU GUYS!!

That hose goes back to your heater core. Extremely easy to change, However you need to be very careful removing the end closest to the firewall. The hose attaches to a plastic switch and is typically fragile from age/heat. Take your time and you'll have no trouble.

Thanks Chris. I do need to remove the distributor cap right?

whole dizzy and a few sensors makes it ALOT easier to get in there, but nor "NEEDED" dizzy is just 3 12mm bolts and a plug(or 2 if obd1).

janos

oh damn, that was easy as well.... I just removed the 2 distributor bolts, removed the top of the hose to the intake and took it off... took like 3 minutes. Now I gotta get a hose.

Thanks so much!

That helped, now I noticed the radiator fan does not work, so it seems that might be the other reason it is over heating. It takes longer now to over heat now, but still is over heating. I can hear the fluid boiling.

Chris Westlund

Did you bleed the coolant system after the hose install?

Jack the front of the car up just a bit, open the radiator cap, top off the coolant and let it run for a bit with the cap off. Make sure you set the heat in your car to max.

Does the car blow cool air, warm air or hot air when the heat is at max?

Constantly overheating like that is bound to do some damage.

I did bleed it and this time kept the car running in the garage. The whole time I kept the heat on and the hood up and slowly watched it increase in temp and turned it off once it got to 3/4 on the gauge. The hoses were all replaced (upper/lower), radiator, thermostat/gasket and the heater hose. I noticed the entire time that the car was running, the fan never once turned on.

I can only think now that the fan needs to be replaced. I just ordered the TYC 600070, so I can only hope this works. I have to be able to drive to school.

janos

That is what I am getting scared of. If it is not one thing, it seems to be something else.

Chris Westlund

Before ordering the fan, Do a little more troubleshooting. Did you try jumping the wiring to the fan to see if it spins at all? I'd hate to see you replace a potentially good fan, Perhaps there are wiring issues elsewhere.

janos

No I have not, how would I jump it to see if it works that way?

Thanks

First things first, Have you checked the fuse in the under hood fuse box?

Edit: Take a look at this thread and let me know how that turns out for you.

Okay, I did just jump it and it worked off a 12v battery. So does that mean it is either the fuse or has to be the themoswitch? could it be anything else?

janos

Okay, I checked out the fuse and it was fine. I replaced the themoswitch and that is exactly what was wrong. After changing it out now my fan turns on. Thank you Chris!

Chris Westlund

No problem, I'm glad I could help.

I love when troubleshooting works out! Nice job, guys.

Might want to change your oil now that its been cooked and lost its viscosity...

janos

I did, the same week I changed out the oil pan gasket. That was a lot of fun...

Thanks so much for everyone's help. Coolant leak is fixed and now I can drive the car without over heating.

what was the hose called? i need one as well and cant figure out what kind of hose it is
