I'll check with my IR thermometer when I get homeI go to RockAuto and follow the menus for my (in this case yours) vehicle.
Intake, for computer: https://www.rockauto.com/en/moreinfo.php?pk=1309928&cc=1033175&pt=4748&jsn=526
Note, it has 2 terminals
Head, for gauge: https://www.rockauto.com/en/moreinfo.php?pk=40504&cc=1033175&pt=4748&jsn=524
Note, 1 terminal
I've never found one that is called out as "specifically for computer." I've replaced them with a 2 terminal sensor and they've worked. There is also a ground on one of the thermostat housing studs. You should clean that when replacing the CTS. What is the temp of the rad hose when checking it with an IR thermometer?
Others can chime in if there are differences..
Don't replace parts until you've done proper diagnosis.So it smells rich while running, stopped at a light its running rough unless i put it in park or neutral. And then my tempature guage has never went higher then this
I was thinking the same thing. It's just been so cold here I haven't wanted to go out and do the work. The guy at the auto store sold me the gasket and the tube of gasket maker. Should I use both?Don't replace parts until you've done proper diagnosis.
First Guess: your thermostat is faulty, the engine never warms up to proper operating temperature. Of course it runs rich, probably fouls spark plugs, and therefore runs rough. I bet you can replace the temp sensor and it doesn't run a bit different. More likely, need a thermostat.
But none of that should be taken as "fact". Connect a scan tool, find out what temperature the computer thinks the engine is running at. If it matches the gauge within reason, you've likely got a bad 'stat. Or drop a thermometer in the radiator coolant, or point an infra-red thermometer at the radiator hose.
No. Gasket Maker is not the same as gasket sealer. Fel-Pro says their gaskets don't need sealer. Not sure I'm buying into that, adding Gasgacinch or High Tack or CopperCoat to a gasket seems very natural to me, and I've had good results.The guy at the auto store sold me the gasket and the tube of gasket maker.

Appreciate that info alot. I'm going to get some gasgacinch today then.No. Gasket Maker is not the same as gasket sealer. Fel-Pro says their gaskets don't need sealer.

DO NOT put RTV Silicone on a gasket. Gasket Makers are used instead of a gasket, not applied-to a gasket.
If this were me, I'd return the gasket maker, and get a gasket sealer instead. Gasgacinch is my current favorite, but there's a dozen products and they all work more-or-less equally well.
