I need your knowledge!!!! I hear about the throttle body coolant line all the time, but can someone actually show me a picture of it? I would really appreciate it. Also, what size hose is it?

Thanks a million.

first line is located near firewall adjacent to a vaccum actuator. Second line is below the throttle body right next to the plastic catch can. line is 10mm I.D. FWIW, I bypassed my completely so that no coolant flows thru the TB.

Je nais parles pas le francais tres bien.

Here you go:





Even Has a Temp sensor mounted in it!



Ps - Not my car, My AutoMeter sender is in the stock sender location

OH cool, thank you both. Thats the hose that cracked on me about a year ago, I think. Well it was one behind the manifold, had to have the manifold taken off to replace, kinda sucked.

Anyway Thanks alot, I'm debating on putting a water temp sensor there or doing the housing thingy.

You know... I had my temp sensor there too... But I never got a reading above like 100F or so... Any idea why?

ZeroBanger

I know why!! I do! I do!!!

sometimes if you use an adapter and your sensor is inside the adapter and doesn't go directly into the stream of water that would cause the problem. For example, lets say you had a 1/8 NPT sender that was placed in a 3/8 adapter to fit into a line, if inside the water line the sender is not extended beyond that 3/8 adapter, you will likely not get accurate readings.

but then again, I'm a New-B that doesn't know crap. Sorry to make you read this.

First it comes from on top of the engine block and then to the top of the tb. Then it goes through the tb and comes out under it. This is the coolant line you have to take off every time you take off the uim and tb that small 5 incher that's a pain and you always forget. From there it goes to near behind the alternator through a hardline.

I know you probably aren't trying to remove the tb coolant but if you are the simplest way is to take the line that goes from the engine to the top of the tb and make it go straight to the bottom line under the tb. Then just cap both places on the tb where it used to go in and out. It's intended for places where it gets really cold to melt ice out of the tb so you don't need it! Removing it is said to cause the car to idle weird on cold starts. I had it removed for a while and didn't notice any weird idling but now I put it back.

BTW I would put the temp sensor in the thermostat housing. Have a pro tap it for you in the correct place so you get the highest readings possible.

Possibly a bad Ground (you have to ground the sensor body if it mounted in an un-grounded location) or plugged pasages in the throttle body restricting coolant flow.

As maxpesce said you probably forgot to ground the sender. My probe is in the upper throttle body coolant line like the one in the pic. I grounded the entire tee to provide the sender with a ground.

That's possible but when my ground came undone the needle pegged itself to 250 or whatever the highest is. I then **** myself and tried to pull over but on the way I hit a bump and it went back to 185 and I figured it out duh damn newbie me.

ZeroBanger

yes, with my gauge it goes to 355 (the max) if the ground gets disconnected.

jdhuegel1

Thanks! I'll be sure to double check the ground.

KINETIK_FD3S

so thats why mine stayed at 100F can i put the ground wire on the same spot as the sender or do i can to ground it to the base like the one on the first picture.

ZeroBanger

you ding dong! Just kidding, On your sender you should have a nut on the top with a washer in the middle and maybe even a white or green insulated washer under that. You want the ground to be as far from the pole (the top of the sender) and close to the body of the sender as possible. On mine there is a green insulated grommit that seperates it from the sender, thats where I ground mine.

back to the original topic...is bypassing the TB as easy as getting a double-sided barbed metal tube and hose clamping it to both lines?

it's as easy as using the original line that's already there and instead of going from the engine block to the top of the tb make it go from the engine block to the line under the tb. Then cap off the place it used to go in and out of the tb and you are done. Removing/Rerouting the coolant flow so it doesn't go in the tb any more.

teamstealth

yea thats what i was saying, xcept make it that much simpler by connecting the 2 hoses rather than removing one and re-routing the other. I tend to not like doing more work than necessary.
