jmoore4294 Posted February 3, 2009 Report Share Posted February 3, 2009 Ok, so I haven't had the car for long, and apparently this is the only thing that the previous owner did not replace, and that is the thermostat. I haven't had a chance to look at it yet. It wasn't hard on my LQ1. Now I have the 3100. What am I looking at here in terms of difficulty? Should I take it to the shop, or can I do it in a day with basic hand tools? Quote Link to comment Share on other sites More sharing options...
Crazy K Posted February 3, 2009 Report Share Posted February 3, 2009 basic tools can do the job. however, the throttle body needs to be separated from the plenum, or the plenum must be lifted for access. also, with the 3100 (and any sideways stat) i drill i tiny hole to prevent airlock at the t-stat.

Night Fury Posted February 3, 2009 Report Share Posted February 3, 2009 Stants come with a tiny hole... Mine did anyways... Quote Link to comment Share on other sites More sharing options...
slick Posted February 4, 2009 Report Share Posted February 4, 2009 The last 3100 I did the thermostat on I didn't have to pull the TB. Quote Link to comment Share on other sites More sharing options...
jmoore4294 Posted February 4, 2009 Author Report Share Posted February 4, 2009 So it is possible to replace it without pulling the TB? I know the air cleaner assembly will have to come off, that is no big deal. Since you didn't pull the tb, was it difficult? Quote Link to comment Share on other sites More sharing options...
slick Posted February 4, 2009 Report Share Posted February 4, 2009 Would have been much easier pulling it, especially if you have big hands. Quote Link to comment Share on other sites More sharing options...
88red4cyl Posted February 4, 2009 Report Share Posted February 4, 2009 Chris is right, it is possible without taking the tb off... When I changed mine last winter, I only took off the air cleaner box... It really sucked, but probably took less time than taking off and reinstalling the tb...

jmoore4294 Posted February 4, 2009 Author Report Share Posted February 4, 2009 Would have been much easier pulling it, especially if you have big hands. Then I may be in trouble. I'm trying to get this done with as little money as possible since I don't have much to throw around, and I kinda need a car to get me to work and back.

GP1138 Posted February 4, 2009 Report Share Posted February 4, 2009 It's not that bad to pull the TB in the first place. I did the thermostat in 20 minutes on my old 3100 car. I'm about to have to do it again. Quote Link to comment Share on other sites More sharing options...
jmoore4294 Posted February 4, 2009 Author Report Share Posted February 4, 2009 Well. I've never pulled a throttle body before. Can't imagine it could be that hard though? Quote Link to comment Share on other sites More sharing options...
Night Fury Posted February 4, 2009 Report Share Posted February 4, 2009 Nah. If I can do it, you can!! Quote Link to comment Share on other sites More sharing options...
Crazy K Posted February 4, 2009 Report Share Posted February 4, 2009 Stants come with a tiny hole... Mine did anyways... if yours has a hole, no drill hole needed. Nah. If I can do it, you can!! but you also lost a bolt! <3 Not too hard. if you pull the throttle body, expect to need a $10 gasket *or make your own from a $2 piece of gasket board material* Quote Link to comment Share on other sites More sharing options...
slick Posted February 4, 2009 Report Share Posted February 4, 2009 Last time I priced checked a TB gasket, it was $3. Quote Link to comment Share on other sites More sharing options...
88red4cyl Posted February 5, 2009 Report Share Posted February 5, 2009 Last time I priced checked a TB gasket, it was $3. I paid 5.49 for mine yesterday.. Still very inexpensive though... Quote Link to comment Share on other sites More sharing options...
jmoore4294 Posted February 5, 2009 Author Report Share Posted February 5, 2009 Well. I ended up letting a friends dad do it. I didn't even think to ask her, but we were talking, and I mentioned it, and she asked her dad and he said he'd do it for $30 if I went and got the thermostat. Not too bad, and at least he knows what he's doing. He used to be a mechanic, not exactly sure what he does now though. Quote Link to comment Share on other sites More sharing options...
digitaloutsider Posted February 5, 2009 Report Share Posted February 5, 2009 $7 and doing it yourself is still a much better deal than $30. Quote Link to comment Share on other sites More sharing options...
jmoore4294 Posted February 5, 2009 Author Report Share Posted February 5, 2009 Well, no argument there. But I wasn't comfortable doing it and not screwing anything up. So I let someone who knows what they are doing do it. Quote Link to comment Share on other sites More sharing options...
Night Fury Posted February 5, 2009 Report Share Posted February 5, 2009 You won't learn if you don't do it! Not hard at all. Quote Link to comment Share on other sites More sharing options...

jmoore4294 Posted February 20, 2009 Author Report Share Posted February 20, 2009 Bump. So I'm still having overheating problems. It was ok for about a week and a half after the thermostat was replaced. Now it's back to doing the same shit. It gets hot, like pegs the gauge kinda hot, then rapidly cools back down then gets hot the rapidly cools back down. Would a water pump be causing this? I'm sure I need a new one. I do have a coolant leak somewhere. What about air in the system? I have no heat. Even with coolant flowing. Plugged heater core? But the heat was working without a problem until I had problems with it overheating. Quote Link to comment Share on other sites More sharing options...
slick Posted February 20, 2009 Report Share Posted February 20, 2009 Did you bleed the system with the heater on full blast (blowing in defrost, heat on full blast, warmed up)? Have you had the system flushed yet? Quote Link to comment Share on other sites More sharing options...
jmoore4294 Posted February 20, 2009 Author Report Share Posted February 20, 2009 No. It wasn't flushed. And we did not bleed it with the heat on full blast. Quote Link to comment Share on other sites More sharing options...
slick Posted February 20, 2009 Report Share Posted February 20, 2009 You need to bleed it with the heater on full blast in the defrost position. Quote Link to comment Share on other sites More sharing options...
AL Posted February 20, 2009 Report Share Posted February 20, 2009 One of my friends had this problem on here 97 Z34... I think it turned out to be the gauge getting in accurate readings so it would go from 195 to overheating and then right back... Quote Link to comment Share on other sites More sharing options...
jmoore4294 Posted February 20, 2009 Author Report Share Posted February 20, 2009 I would call faulty gauge, but I have no heat so something isn't right. Quote Link to comment Share on other sites More sharing options...
