SOURCE: new manifold

Hi I would just break the tube off, I'm trying to picture the tube, you said it goes exhaust to intake manifolds, its attached from one to the other? To me for what to said about the tube that its some kind of emission device almost like how a turbo works. so I would just disconnect the tube. Which manifold are you replacing? Hope this helps

cheers

We have a 02' Expedition Edie Bauer, we first started having trouble with hole in manifold so it is a lil loud. Then we went to start it after we just drove about 40 miles and it would not start it ga


the hole in the manifold is the problem, as the ECU is trying to manage the air/fuel mixture and this hole is messing up the readings ,so the ECU will shut down the engine incase of causing damage , get the manifold replaced , even if its the exhaust manifold, as the exhaust gas's are read as well and some are recycled into the inlet manifold , this is a critical part of the engine management system

My serpentine belt broke drove car 30 miles home without belt, got a new belt put it on cranked car up took for test drive got back opened hood realised the exhaust manifold was red hot. Turned A/c off...


  • Well, that belt drives everything including the water pump. When the belt broke and you drove it no coolant circulated and the exhaust glowed from overheating. A red glowing manifold usually only happens from excessive heat caused from modified engines. But in this case this is almost surely what happened. You are lucky you did not blow your engine. Park it and let it cool down for a few hours.

Coolant antifreeze is coming out of the exhaust but the car isnt loosing any power


You have a blown head gasket, intake manifold gasket, or exhaust manifold gasket. This will eventually cause serious engine damage; get it fixed right away.

I have a 97 kia sportage. I think i have a exhaust leak. can that have the check engine light on? AND is that the manifold that need to be fixed?


Yes it will turn on light. Replace exhaust manifold only if it is leaking. It could just be loose or damaged gasket or hole or crack pipe.

2002 KIA spectra exhaust manifold


The exhaust manifold is right there as soon as you open hood , first disconnect neg batt cab, then jack up car remove bolts that hold pipe to manifold together , unplug any o2 that is in the way and that could get damaged. now from the top take shield off then take manifold bolts out. you might want to spray them with pb blaster and let set a few hours sense exhaust bolts love to break. Remember to use new gaskets installing new one.

How to replace the water pump on 1993 oldsmoblie achieva.


2.4 enigine is the harder of the 3 enignes. it will need a timing chain to be removed and a coolant tube in the back of the engine to be removed. this job on the book calls for almost 7 hours.

if its 3.3 or 3100 its alot easier.

3100 is just 4 10mm pulley bolts and 5 or 6 small 8mm water pump bolts.

3.3 is alittle more work, but same concept as 3100 engine. more owkr only cause its in a tighter area.

good luck,
michael
