My wife blew her head gasket and mechanic says we need a new up and new down sensor as well as a new converter. total cost is 5400 on a 2006 elantra
I would wait on the cat. Have the heads and sensors done and see if the cat burns the coolant off.
my mechanic says it was burning the coolant off and since i am in California the converter is alot more expensive. The entire repair seems high to me but i am not too sure
When the head gasket failed, coolant entered the cylinders and was turned to steam and entered the exhaust. It may have fouled the oxygen sensors which is the up and down sensors that the mechanic is talking about. Depending on the antifreeze that you used, the issue might be a silicon additive that is in the coolant and it can cause the cat to become fouled. I would still wait to see if you fail emissions before replacing the CAT. It might not have affected it but you cannot be sure without an emissions test.
assuming i need a CAT is that price for everything high? $5400?

SOURCE: 1992 LS 400 Lexus. Car wouldn't start. New
remove black plastic relay cover in plastic underhood fuse box and activate relay
with a very small screwdriver and ignition on. If starts, obviously the starter is fine, if not the starter is indeed bad and needs replacement so hold onto your ankles cuz it's gonna hurt.

YOU REMOVE THE 4 BOLTS BEFORE AND AFTER THE CAT.
ENSURE THE OLD INLET AND OUTLET GASKETS ARE REMOVED AND REPLACED BE FORE INSTALLING THE NEW CAT WITH NEW BOLTS.
ABOUT $800 FOR THE PART AND A HOURS LABOUR.
AN MUFFLER SHOP SHOULD BE ABLE TO INSTALL A UNIVERSAL
CAT FOR LESS.

SOURCE: Catalytic Converter for Honda CRV 2002- cost/necessity of repair
run scanner for trouble codes, some auto parts stores will do this for free
SOURCE: I have been told that my catalytic converters are
you can do it yourself it will only cost the price of the catalytic converters, first i would disconnect them and visually inspect them if you see that they look like a honey comb with no obstruction of the holes than they are fine but if you see black residue or even some melting of the material than i would replace them. hope this helps you.

California has more stringent rules on CATs. The cost for one is about 500 but could be as high as 1000. The nice thing is that they have a warranty that is pretty good so you might be able to say it was a warranty failure if you dont have it replaced when the work is done. Shop labor is going to be expensive especially at a dealer. They charge about 200 an hour minimum. The heads might need to be planed to make sure they are not warped. I am thinking 5400 even with a 1000 CAT is kind of high.
my mechanic said the cost of the CAT was 950 or so and he gave me labor for free. replacing the gaskets and all the hoses was 3600 or so with labor then add in all CA taxes
I guess that is about right, the problem is that the shops have a flat rate charge and if they can do it in less time, they dont cut you any slack. To give you an idea of the job, remove air intake, intake manifold, fuel lines, drain radiator, remove exhaust manifold, remove head, clean cyllinders, remove gasket, check for warp on the head, if warped plane the head, replace the gasket, replace all the parts, change the oil and coolant. I dont know why hoses were replaced. There can be a lot that can go wrong too.
on the hoses i am not totally certain. it seems like this is an iterative process and you can't determein B is messed up till you fix A then downward. Had i known at the beginning this would cost 5400 i would say junk it. i appreciate you help. you have been awesome.
Book value on the car is 5866
