solid snake Posted March 31, 2006 Share Posted March 31, 2006 As most of you know I had my t-belt changed a couple of weeks ago, since then i have noticed that the temperature gauge gets to the mid point very quickly. I placed a new 170 degree t-stat and changed the radiator cap on it. But the temperature is still at the half way mark. I was in line coming back from Mexico on Wednesday for about 30 minutes and it started to heat up, it was porbably 3/4 or a little more from the high side. Before when I was in line it didn't heat up, but cool down. I saw the temp fall, now it increases, I'm actually pretty worried about it. Could the t-belt have anything to do with this?

RedPath88 Posted March 31, 2006 Share Posted March 31, 2006 (edited) These questions may have been asked before, but... Is your fan working correctly? Any wires disconnected or loose... have you checked and rechecked all the connections to make sure (if disconnected) that they were hooked back up the proper way after the T-Belt replacement? Is the relay working correctly? Anything damaged (wires/relay/sensor rod/etc)?... was the fan physically reinstalled properly? Could it be binding? Can you hear it turn on and off... is it doing this correctly? Edited March 31, 2006 by RedPath88 Link to comment Share on other sites More sharing options...

Is the relay working correctly? Anything damaged (wires/relay/sensor rod/etc)?... was the fan physically reinstalled properly? Could it be binding? Can you hear it turn on and off... is it doing this correctly? The fan is working properly, it has a e-fan, no wires look disconnected. I pulled apart the whole set up to see it the thermostat was installed properly, everything looked in tip top shape, put everything in it's place. Haven't checked the relay, but I can smell the heat from the engine when i park my car. I didn't use to smell it before. Sonsor rod? where can I find that? I hear the fan turn on and off correctly. i will replace the clutch fan and remove the e-fan to see any changes. Link to comment Share on other sites More sharing options...
RedPath88 Posted March 31, 2006 Share Posted March 31, 2006 If the fan is turning on and off as it always has then the sensor should be fine, but it cannot hurt to look anyway... "Sensor Rod" is for the lack of the proper term (just cannot remember the right name for it now). It is the metal (brass?) rod with a couple of electrical contacts on it which is pushed through the radiator fins and secured in place. It detects the temperature and either supplies or cuts the power to the relay (which in turn provides power to the fan motor) Another thought... Is your cooling system becoming over pressurized? Does the water/coolant in the overflow reservoir ever overflow or boil? If so you may have a blown head gasket. Link to comment Share on other sites More sharing options...
94extreme Posted March 31, 2006 Share Posted March 31, 2006 burp the cooling system man. it has trapped air in it. you said you changed the t-stat. i bet that's the problem here. Link to comment Share on other sites More sharing options...

I'll double check it though. Link to comment Share on other sites More sharing options...
94extreme Posted March 31, 2006 Share Posted March 31, 2006 there is a little plastic screw in the upper hose that you have to loosen and run the car and let the water circulate a few times. heat on full blast. or you undo the rad cap and do the same. the first method is better.

Slick Posted March 31, 2006 Share Posted March 31, 2006 yes.. burp the old girl first.. but my pathy was doing that also (temp up n down like a yoyo.. heater hot then cold) and it had a blown head gasket.. tho she really didn't show signs til late in her illness :sniff: Link to comment Share on other sites More sharing options...
94extreme Posted March 31, 2006 Share Posted March 31, 2006 head gasket is a definite possibilty. i just thought he ought to start with the simplest stuff. and he didn't mention yo-yo effect. the high temp reading is a classic trapped air symptom.. not that there couldn't be some other issues.

solid snake Posted March 31, 2006 Author Share Posted March 31, 2006 No yo-yo effect here, checked the resevoir and there is no boiling water either, let her ran about 1o min with out the rad cap on. Temp did not go down remained the same. Link to comment Share on other sites More sharing options...

solid snake Posted March 31, 2006 Author Share Posted March 31, 2006 i saw the little plastic screw you were talking about, but not along the upper hose, it was on the opposite side of the lower hose. It was really hard to budge. It was attached to a hose that runs downward. Link to comment Share on other sites More sharing options...
solid snake Posted March 31, 2006 Author Share Posted March 31, 2006 heat on full blast? Yup, unless maybe I can turn the a/c on to have her run at a higher temp sitting at idle. Link to comment Share on other sites More sharing options...

It was attached to a hose that runs downward. :o please don't tell me it was anywhere near the radiator? that's the a/c! here's a pic of where the burper is.. 10mm socket and undo a bit but don't remove.. put rad cap back on and run to working temp or until water *starts* spewing out of the hole (my pathy will not burp with the rad cap off.. she's awkward like that) then let spew for a few minutes.... mine likes to barf up for about 10 minutes ...

solid snake Posted March 31, 2006 Author Share Posted March 31, 2006 (edited) Thanks for the pic Slick, I wasn't trying to burp the rad from the a/c. I'm not that dumb. But from the pic that you showed me I think that the one I have to burp her from should be the hose next to the pcv hose right? Heres the pics. This is the one I was trying to open Edited March 31, 2006 by solid snake Link to comment Share on other sites More sharing options...
94extreme Posted March 31, 2006 Share Posted March 31, 2006 the bottom pic is of petcock to dump the coolant. the one i am talking about is in one of the upper hoses. don't see it in the pics. it's a little plastic piece and hoses on both sides. the screw is in the plastic part.

Slick Posted March 31, 2006 Share Posted March 31, 2006 i can almost see which one you need to open.. it is there by the hose on the intake yes.. it has a copper washer if that's any help and it's by itself up there Link to comment Share on other sites More sharing options...
94extreme Posted March 31, 2006 Share Posted March 31, 2006 copper washer sounds about right. it has been years since i even looked at that thing. i am not sure if my 94 has that doohicky or not. might look tomorrow if i remember. Link to comment Share on other sites More sharing options...
