Cueman Posted January 8, 2006 Report Share Posted January 8, 2006 Help! I have taken out both of the bolts for the thermostat housing on a 95' 3100 SFI, but I cannot get the thermostat or the pipe out. Is there a trick to this? Would taking part of the intake or plenumn off give me more clearence? If some could give me a quick walkthrough on how to do this I would really appreciate it! Thanks in advance!

Robby1870 Posted January 8, 2006 Report Share Posted January 8, 2006 Did you take the Throttle body off? Quote Link to comment Share on other sites More sharing options...
DiscoStudd Posted January 8, 2006 Report Share Posted January 8, 2006 If you managed to get both bolts out, the housing should come right off. Just grab the housing where the radiator hose slides on, and pry outward. I managed to get the housing out of my 95 GP without removing anything except for the airbox. I also unbolted the heater pipe that goes into the top of the water pump and raised it up a half-inch or so in order to get to the T-stat housing bolts, but it sounds like you've got that licked...

Cueman Posted January 8, 2006 Author Report Share Posted January 8, 2006 I cannot pull the pipe straight out, I have been pulling and twisting for 2 hours now! Ther dosen't seem to be enough clearence. Robby, how hard is the throttle body to get off? I think this might give me enough room. Could someone give me a quick guide to removing the throttle body? Thanks Quote Link to comment Share on other sites More sharing options...
digitaloutsider Posted January 8, 2006 Report Share Posted January 8, 2006 If you take the TB off, go ahead and get yourself a nice lengh of the same size hose and just bypass the throttle body. Quote Link to comment Share on other sites More sharing options...

digitaloutsider Posted January 8, 2006 Report Share Posted January 8, 2006 It's really pretty straightforward.. Remove the throttle cables and any hoses and harnesses attached to the TB Remove the 2 (I think) bolts. Remove/cut the throttle body heater lines You may need to buy a new TB gasket.

Robby1870 Posted January 8, 2006 Report Share Posted January 8, 2006 I havent done a 3100 TB in a while, but there are two bolts that hold the TB to the plenum. Take those off and you might have to undo some sensor plugs, but you should able to keep the throttle cables connected. Basically, just take off what you need to get it loose. It is only held onto the plenum by two 13mm bolts. Quote Link to comment Share on other sites More sharing options...
Cueman Posted January 8, 2006 Author Report Share Posted January 8, 2006 Thanks for the help everyone! Once the TB was off , it was easy to finish Thanks again Quote Link to comment Share on other sites More sharing options...
THe_DeTAiL3R Posted January 9, 2006 Report Share Posted January 9, 2006 Aren't the 3100s a wonderful engine? I miss my 2.8 Quote Link to comment Share on other sites More sharing options...
Bri-Guy-GA Posted October 27, 2006 Report Share Posted October 27, 2006 If you take the TB off, go ahead and get yourself a nice lengh of the same size hose and just bypass the throttle body. Why would you want to bypass the throttle body? Doesnt it get coolant for a reason? Quote Link to comment Share on other sites More sharing options...
digitaloutsider Posted October 27, 2006 Report Share Posted October 27, 2006 The idea is that it doesn't get stuck in the frigid cold winters. Seeing as how I don't think anyone's ever had that problem, and the spring inside the throttle body is incredibly strong, it's worthless. On the 3100 it really gets in the way when you're trying to pull the TB. It's hard to get them off without cutting them. I took the easy way out on our 3400 and simply cut the lines and bypassed the TB. Quote Link to comment Share on other sites More sharing options...
Robby1870 Posted October 27, 2006 Report Share Posted October 27, 2006 If you work on vehicle a lot, its easier to have the TB coolant lines bypassed b/c the TB is 10x easier to remove if the coolant lines aren't there. Quote Link to comment Share on other sites More sharing options...
19Cutlass94 Posted October 27, 2006 Report Share Posted October 27, 2006 I dont have any coolant lines going to my TB. Maybe its just the year... Quote Link to comment Share on other sites More sharing options...
THe_DeTAiL3R Posted October 27, 2006 Report Share Posted October 27, 2006 Is this line the one that comes from the heater core?? Quote Link to comment Share on other sites More sharing options...
GIANT MOTH Posted November 7, 2006 Report Share Posted November 7, 2006 I don't get it. The thermostat housing can only be removed if the coolant line and intake/shield are removed. It's probably just the make and model. It's one of my favorite things to do especially when I need to put back in the 195 thermostat this time of the year which is crazy because this thing didn't even come with a thermostat.
