This is the first time I have ever heard of sludging in a Hyundai engine. I run 10W30 Castrol GTX in every Hyundai I have owned and have never had an issue. Our summers range from mid 70's at night to low 100's during the day. Our winters will rarely go below 30, and then never in the teens.
Section 8, page 10, 2010 Elantra Touring Owners Manual:
Recommended for maximum fuel economy, 5W20. "However, if the engine oil is not available in your country, select the proper engine oil using the engine oil viscosity chart."
Which, in the chart just above that statement, call out 10W30 for temp ranges from 0 to 120+ degrees F, or 5W20 or 5W30 for temps ranging from -10 to 120+ degrees F.
It was the same in my 2002 and 2005 Elantras. And the Hyundai Platinum Certified technician at my dealership stated that for our climate 10W30 is recommended, but 5W20 can be used. He was very clear about one thing, though: Castrol GTX or Valvoline only. Would not recommend any other brand.
I figure it's Hyundai's owners manual publication, so if they say the 10W30 is good, that's what I will use. And I have used nothing but Castrol GTX since 1968 and have never, ever had and oil related engine failure nor sludging. The proof is in the pudding, or in this case, lack thereof.

I have a 04 Elantra with 86K, recently I noticed on hot days if I park in the sun the MIL will come on with code P 1723 and P 1529, input/output speed sensor and auto trans relay switch. If I park in the shade or it's cool out the light won't come on. Anyone else experience this? I'm not sure where this relay switch is, but could it be something that is getting stuck with the heat and swelling? Thanks for any info.
#3334 of 3420 '02 Elantra overheated engine
Jul 21, 2010 (2:32 pm)
Our 2002 Elantra GLS with about 35,000 miles overheated while driving along, with no warning. Car was towed to the shop that maintained the car all through since '02. They replaced the radiator, but the car continued to overheat. Head gasket was replaced next, and now damage to the engine block is suspected to be the cause of the problem (head assembly checked out okay).
Question is if it is worth spending the 3400 or so on the engine. Seems like the car is fragile enough that it would be a bad bet to sink more money into it.

If you have owned the car since new, it is still covered under the powertrain warranty. Check with Hyundai re coverage of the engine block. If that was the cause of the problem, you can make a claim on the warranty. But if the cause really is "damage", as you said, and not a defect, that would not be covered.
If that doesn't apply, you could look for a salvage engine. The car isn't worth much more than $3400.

There was an issue several years ago with thermostats in some Elantras. Upon failure, the engine would suffer sudden and extreme overheating. These were covered by Hyundai under the 10/100K warranty to the original owner.
I would strongly suggest you get the dealer involved right away. There will likely be an issue with reimbursement since the original diagnosis and repair was not performed by a dealer. I assume the shop you mentioned was not a Hyundai dealer as they would have known immediately that the thermostat should be investigated.
Regarding the fragility of the '02 Elantra, no. The little buggers are tough, but I know of several that suffered blown head gaskets due to the thermostat issue. The 2.0L engine that Hyundai uses (and still uses in the 2010, but with CVVT) is very durable.

I have a 2002 Elantra GT and as jlflemmons mentioned, I had a thermostat problem that caused the car to overheat quickly back around 2006 or so. Got the thermostat replaced for about $100 and it's ran perfectly since then. I'm starting to have some leaking from the engine block maybe (I'm not a car guy, not sure if I'm using the right term), but I'm told that's a pretty simple fix (another $100) to replace a gasket.
I'm loving this little bugger, I'm around 136k miles, about to replace my timing belt for the 2nd time since I did it so early the first time (around 55k miles, guy talked me into it).

The shop (not Hyundai dealer) checked this, and in this case the thermostat was okay. Hyundai did refuse coverage under the warranty claiming that the problem was caused due to damage. Seems kind of unreasonable since no warning lights or indications of a problem were seen before this incident.
#3339 of 3420 It's been asked I'm Sure but...
Jul 29, 2010 (3:41 pm)
with 167 pages, I just don't have the heart to go back 10 years!!! LOL!
I have a 2005 Elantra that I love, and the husband that I loved recently passed away, leaving me to take care of lots of things that I never took care of before, including the car. Recently, as I get the car to 60, it starts to vibrate, for lack of a better word. The steering wheel vibrates as if I'm on a road that needs some repair.
Before I take it in to be looked at...any thoughts about what I should be listening to the dealer say?
I live in MA where we are in the midst of a "discussion" about who should be doing repair and warranty work, so I definitely have to take it to the dealer to at least get an "opinion" and am happy to take it somewhere else for a second opinion.
Any help is much appreciated.

The good news is, this could be an easy and cheap problem to fix. The 2001-6 Elantras are very sensitive to wheel balance. If they are not balanced carefully, you can get exactly the symptoms you described. What I recommend is, take the car to a good tire shop that has a Hunter wheel balancing machine. (Your Hyundai dealer may not have this, but you can ask them.) They seem to do the best job correcting this issue on the Elantra. Then be sure to test-drive the car after the wheels are balanced, and bring it back right away if the "shimmy" (as it's called) is still there.
On my 2004 Elantra, the current tires are not great quality and it takes some care to balance them. The shop where I got the tires, Discount Tire (a chain), sometimes takes 2 tries to get the balance just right. They have the Hunter machine. But they did eliminate the shimmy that appeared when I put this 2nd set of tires on four years ago, and since then.
