BLUE84GLWAGON Posted January 11, 2009 Share Posted January 11, 2009 1st time getting my wagon pretty hot ,enough to overflow warmed it up good and drove around the property pretty hard.i parked it and noticed the temp gauge higher than normal ,i dont use this as a daily driver anymore. I`ve had very minimal problems since i took ownership 4 yrs ago, the coolant level was fine afew weeks ago when i changed the belt . Thanks for any input danny Quote Link to comment Share on other sites More sharing options...
jonas Posted January 11, 2009 Share Posted January 11, 2009 Follow the top (passender side) radiator hose from radiator to the engine. Quote Link to comment Share on other sites More sharing options...
BLUE84GLWAGON Posted January 11, 2009 Author Share Posted January 11, 2009 Thanks man,what temp thermostat do you rec, i live in texas, the weather changes faster than normal danny Quote Link to comment Share on other sites More sharing options...
jonas Posted January 11, 2009 Share Posted January 11, 2009 I would go with what is recommended for your car. That should be fine. Hell, you being in Texas, you could most likely run without one and be just fine, just take a little bit longer in the winter to warm up.

hatchsub Posted January 11, 2009 Share Posted January 11, 2009 Stock is a 195 i believe. If you think its running a bit warm with that go to a 180 or a 185. I wouldnt go any lower than that however. Quote Link to comment Share on other sites More sharing options...
BLUE84GLWAGON Posted January 11, 2009 Author Share Posted January 11, 2009 Thanks ,i went back out and filled up to op level and watched it gradually rise back to a bit under hot and then turned it off.however i do remember i did replace the cooling fan a couple of years ago. How do i trouble shoot the fan? Quote Link to comment Share on other sites More sharing options...
BLUE84GLWAGON Posted January 11, 2009 Author Share Posted January 11, 2009 I`m sorry i asked how to check the fan, i meant the sensor activates the fan, and i don`t even know why i asked where the thermostat was i guess i was just dizzied by the fact something wasn`t right about my wagon , except that i cant drive it often as i want to thanks danny Quote Link to comment Share on other sites More sharing options...
Greenley Posted January 12, 2009 Share Posted January 12, 2009 You're referring to the thermoswitch in the radiator. If the fan is not coming on when the temp gets up there, chances are it's toasted. You can play the replace-a-part game with it, but i went through enough of them to bypass it and wire my fan(s) with a relay and cabin toggle switch.

Phizinza Posted January 12, 2009 Share Posted January 12, 2009 180 degrees F is std I think Quote Link to comment Share on other sites More sharing options...
BLUE84GLWAGON Posted January 12, 2009 Author Share Posted January 12, 2009 Whats the procedure for the bypass. I know i would probably need 10ga?? Wire a good toggle and good connectors,heat shrink ??????? Where to i tie in to the power and how do i do the relay? Thanks danny Quote Link to comment Share on other sites More sharing options...
Greenley Posted January 12, 2009 Share Posted January 12, 2009 So i take it the fan does not come on at all? Prior to running switched power, try a jumper wire to the fan, to see if your fan even works. Check the connections at the fan and thermoswitch, they can jiggle loose Check your ground wire at the radiator. Quote Link to comment Share on other sites More sharing options...
Skip Posted January 12, 2009 Share Posted January 12, 2009 This post is getting a bit away from the original question but You might want to look at the fins on the radiator, front side down low They tend to delaminate from the cooling tubes. You do not mention AC, it can change the fan wiring. Follow Mr Greenley's advice. then if you want the best of both e.g. a rad thermoswitch and cockpit switch both controlling a relay) Try this diagram I made up for you standard lighting relay 12 AWG for the power 18 AWG for the switch gear.

BLUE84GLWAGON Posted January 12, 2009 Author Share Posted January 12, 2009 i tested the fan,it works, tell the sensor to turn the if the t-stat was not opening would that not tell the sensor to activate the fan, for example,when a radiator is empty the temp gauge wont show hot because no coolant is flowing by????? i am about to install the t-stat, i already have it up on ramps to try to relieve the air pockets are there any other tricks i need to know about thank you`ll very much danny Quote Link to comment Share on other sites More sharing options...
Skip Posted January 12, 2009 Share Posted January 12, 2009 i tested the fan,it works, You found this out by?????? Do you see a small wire running from the top of the rad to the core support? You should, as it is the ground for the fan. tell the sensor to turn the if the t-stat was not opening would that not tell the sensor to activate the fan, Well I don't know what to make of this. But if the T-stat was not opening the temp would go high enough to turn the fan on. for example,when a radiator is empty the temp gauge wont show hot because no coolant is flowing by????? This is true, but why is there no coolant in the rad?? i am about to install the t-stat, i already have it up on ramps to try to relieve the air pockets are there any other tricks i need to know about Leave the cap off, start the car, and keep a drain pan under the front. keep filling until the engine temp is up to op temp for several minutes Cap on and fill coolant bottle to min. Sugg, use and OEM t-stat NOT a Stant replace the cap while you are at it. Quote Link to comment Share on other sites More sharing options...
BLUE84GLWAGON Posted January 12, 2009 Author Share Posted January 12, 2009 Thanks skip,sorry for my confused wording,i did have coolant in the radiator,i got the t-stat in and messed around filling it up a little at a time , i never heard the fan come on although the temp was around normal, i jiggled the sensor wire again, and as someone had mentioned the wire to the sensor was just riding on the nipple of the sensor so i crimped it a little and waited,then it came on!!!! And i really appreciate all of you helping me out. I am gonna do the bypass as you diagrammed because i dont want a blown head gasket or worse / thanks for the time and diagram , i got a little more familiar under my hood today danny Quote Link to comment Share on other sites More sharing options...
Aces Full Posted March 24, 2009 Share Posted March 24, 2009 Skip, Could you repost your relay diagram. For some reason I cannot view it. Thanks Quote Link to comment Share on other sites More sharing options...
rpholz Posted March 25, 2009 Share Posted March 25, 2009 as far as a bypass Advance Auto parts (or whatever it may be in your location) sells this neat little relay for like 15 bucks and you wire it in to a 12v constant 12v switched(i left this on constant in my case, laziness) a ground and a probe that goes in the radiator as a sensor. then you just let the car warm up and turn a dial until the fan comes on. really reliable and practicle. just replaced the clutch fan in my xt with a a/c fan out of the junk yard and used this set up. never had a problem with heat whats so ever. ill get pics, looks too cool lol good luck!
