Mantonite Posted March 29, 2006 Share Posted March 29, 2006 My '94 Loyale's temp gauge used to sit nicely just above the "C", but has been sneaking up lately. It is full of coolant, before you ask. Any ideas other than HG? Quote Link to comment Share on other sites More sharing options...
NoahDL88 Posted March 29, 2006 Share Posted March 29, 2006 maybe its just that its getting warmer. Make sure that your fan comes on, and it wouldn't hurt to pull your T-stat and make sure its opening and closing, or just get a new OEM one and put it in.

mikeshoup Posted March 29, 2006 Share Posted March 29, 2006 Thermostat Then flush the radiator Quote Link to comment Share on other sites More sharing options...
idosubaru Posted March 29, 2006 Share Posted March 29, 2006 what was said. thermostat. make sure fan(s) are coming on. flush radiator. water pump. all of these are more likely than head gaskets unless it's been overheated in the past.

89Ru Posted March 29, 2006 Share Posted March 29, 2006 Might be something, but my EA82 fluctuates between just above the C and 1/3 up on a regular basis. It used to drive me crazy, now I try to ignore it. If it spikes into the red, then you've got problems. Try loading the engine and see if it climbs. I had a clogged radiator once and running the a/c on the highway with a full load on the roof rack would send it up in a hurry. Check your clamps for leaks, if the pressure drops a bit you might see a little temp rise.. Quote Link to comment Share on other sites More sharing options...
Mantonite Posted March 29, 2006 Author Share Posted March 29, 2006 All good thoughts... some more background: T-Stat replaced and rad flushed 6K ago. Tried a higher temp (non-OEM) one and it promptly overheated (trapped air or something). Wen't back to the other one and it worked fine. It's not OEM though... now that I know more about that maybe it's time to get a real one. Cheapest supplier? I'll check the fans, but I doubt that's it as I have an open-road commute. The 60 MPH wind would overpower the fan anyway. I'll take a look and report back! Maybe I'll just pull the T-stat entirely and see if that helps.

Subarian Posted March 29, 2006 Share Posted March 29, 2006 How hot is hot? If it's in the middle of the normal range, I wouldn't worry about it. Quote Link to comment Share on other sites More sharing options...
NoahDL88 Posted March 29, 2006 Share Posted March 29, 2006 Maybe I'll just pull the T-stat entirely and see if that helps. BAD IDEA For 2 reasons, your engine will never heat up, so you will get fuel puddeling and horrid mileage, and also the T-stat acts as a restriction, giving the coolant enough time to pick up heat, so without it you will be running cooler, but you'll have hot spots.

operose Posted March 29, 2006 Share Posted March 29, 2006 best place to get a thermostat is the dealer Quote Link to comment Share on other sites More sharing options...
RONAN Posted March 30, 2006 Share Posted March 30, 2006 years ago my temp gauge slowly started to climb and it turned out to be a worn out clutch fan. Just a thought... Quote Link to comment Share on other sites More sharing options...
jeffast Posted March 30, 2006 Share Posted March 30, 2006 best place to get a thermostat is the dealer i completely agree i have had aftermarket thermostats die on me more than once within a month of installing them Quote Link to comment Share on other sites More sharing options...
gemery10 Posted March 30, 2006 Share Posted March 30, 2006 if all that fails the actual guage can be faulty. I've seen it happen recently Quote Link to comment Share on other sites More sharing options...
Mantonite Posted March 30, 2006 Author Share Posted March 30, 2006 All good thoughts. I can hopefully dig into it this weekend. I'll pull the stat for diagnosis only... if it fixes it I will get a new one in there ASAP. Thanks for all the ideas! Quote Link to comment Share on other sites More sharing options...
Mantonite Posted April 4, 2006 Author Share Posted April 4, 2006 Well, I went to dig into the issue and pulled the rad cap... DRY! It took about 3/4 of a gallon to fill 'er up. I'm thinking rad cap... can anyone verify/deny? Quote Link to comment Share on other sites More sharing options...
