Okay so I have driven my rex around the past two days and almost everytime after driving it for a while then stopping at the store or friends house or w/e the very front of my car smokes. It smells like coolant but i cant find a leak anywhere. any suggestions?

 

What year is your car?

Possible leak would be from the coolant O rings in the intake manifold dripping onto your exhaust. Look under the manifold for residue marks.

Does it smell sweet to you? That would be coolant. If it leaks from the manifold when it is off, it will also be getting sucked into the engine when you are driving.

 

are you sure it's coolant? when my water pump had a small crack in it it wouldn't steam at all, and it was a constant flow of coolant. on the other hand when one of my omp lines broke it would smoke all the time until i realized that it broke lol. took about a day to find this cuz my engine was so dirty. the bottom of the rubber in one of the hoses had rotted off. thank god it didn't do major damage.

 

If it's in the very front of the engine bay, check the radiator for leaks, radiator cap. Is the coolant reservoiur,(sp) over flowing? Then move rearward in your search to the hoses, waterpump weep hole, etc.. Are you losing coolant?

 

i fill the overflow reservoir tank up and it seems to drain almost all the way so i know its coolant unless its supposed to do that two is there is smoke coming from under the exhaust manifold cowl. someone said there is a vaccum or coolant line that runs near there or it could even be the o rings------------------if it is the o rings how would i go about replacing them??

 

using information gleaned from the FSM available to download in the link in my signature.

or by removing the intake manifold/carb and throwing some new ones of freeze plugs instead

And im pretty sure there is nothing coolant related UNDER the exhaust manifold. sooo id say its ur intake manifold o-rings

 

alright man thats what i thought it was. I appreciate the help. Know anything about doing body work?

 

a little depending what u need to know. Also instead of installing new of freeze plugs i meant

"install new o-rings OR 20mm freeze plugs"

 

lol wtf are freeze plugs??

 

these are freeze plugs:

^^sorry to jack the thread, but when i replaced my gasket i saw those, now why does it need to run coolant through the manifold? just for cooling, or does it have some other special job? i thought about just plugging them but i didn't know if it would hurt anything.

 

Heating passages in the intake for cold weather operation. Freeze plugs stop the coolant from entering the intake, and prevent the leak, the downside is poor atomization of the fuel/air mixture in cold weather. Starting around 40degrees the intake and carb can get chilled into poor function/effiency.

On a side thing, I have wondered if the additives in the coolant have caused the O-Rings to expand into mini-donuts. The last 6 I have seen were xpanded and split, rather then dry cracked from cooking.

 

I would also check the rubber seal that goes under the water level sensor....when mine leaked, it smelled with a bit of occasionally smoke...
