Hello, m driving a 2009 grand starex with 107,000km. As part of the dealers PMS schedule they recommended to replace the timing chain, and drive belt. My problem is when going on a steep incline under 20kph my car would just crawl so I tried the same hill but this time with more speed around 30kph my car performs normal, climbing the hill easily. Another observation is that there is a slight delay upon acceleration and my rpm seems higher than before. Dealer told me to replace the egr valve and had my egr blanked along the process but still did not solve the problem. The problem occured even before the chain & belts were replaced. Hope you could help me w/ my problem. Thanks in advance!

Dude honestly I don't know for sure but I would definitely ask at a car parts shop. They are less likely to try and give you some crazy story because they wouldn't be the ones making money off of repairing your car. If I had to guess though I would say that it might be your transmission not switching because it is under too much stress pushing the car up the hill and so it doesn't switch to a higher gear. Not meaning your car can't handle it but that it simply won't switch gears because doing so could make your car slip backwards. Anyway, I hope someone with a bit more experience comes along and can give you a better idea but that's what I've got.

Good luck.

SOURCE: Recommended replacement interval for timing belt on 98 Land Cruis

Ok, here's the deal:
An accessory belt (commonly referred to as a serpentine belt or a V belt depending on application) is rubber and drives your accessories like power steering, air conditioning, etc. These are usually cheap and can be seen and replaced easily.

The TIMING BELT is also rubber, however it's job is much more critical. Basically, it times the bottom part of the engine with the top part of the engine. It is NOT seen without having to take a few things apart. It is NOT for the novice mechanic. However it is also usually not that expensive for the belt either. It's the intensive labor that's the cost factor.

Your engine is an "interference" engine. Meaning that if that timing belt breaks, then valves will contact pistons. That means ka-boom and major $$$.

You will not not a performance difference until the belt breaks. At that time it will be too late. Valves will be bent, pistons may crack, heads may be damaged.

The mileage recommendation on getting the timing belt changed is just that: a recommendation. They can last a lot longer, and sometimes not so long. As long as the belt doesn't break, you're good.

Seeing as how you've gotten twice the normal mileage out of that once belt, then I'd count your blessings and get it changed. Do I think you can get it done for less then $1500? Yes, without a doubt. Just price shop with other mechanics.

So the only question is, does your truck have any other major problems. If it's like most Toyota's, then probably not, which means it'd be worthwhile getting the timing belt done. The engine should last a long, long, time yet. Plus it's an excellent selling point if you want to ever sell that vehicle.

If you have other problems, then just wait til the belt breaks, because it will eventually, that's just how it is. At that point you can replace the valves and repair the heads and possibly pistons, or get a new or used engine to put in.

The cool thing is that while they go in and replace the timing belt, they can do a lot of other things very very cheaply, or at least, they SHOULD. For instance, they can replace that serpentine accessory belt since they have to take it off anyway. The water pump is also sitting right there.

So just be sure to ask them these options. It'll be a lot cheaper to get them all done at once, rather than waiting until they go bad and having to make a 2nd trip. For instance, get the timing belt done, and THEN finding out a month later your water pump is going bad and that they could have replaced it then...

In summary, if you like the vehicle, just get the timing belt done if it's due. And shop around and get it done reasonably. It'll be way cheaper than the head work and/or a new motor.

What causes Soltice to rev up and down shift when climbing hill but loose speed

That is the way gears in cars work. When you go up hill, the car needs more gas, so you put your foot down, kick down comes into play and the gearbox chooses one gear lower, for more engine revs and lower speed you get more torque to climb the hill.

Get the car tuned up, you might have failing sensors or ignition problems causing a general loss of power that is needing kick down on hills.

RPM's go high when driving but then go back to normal

What you are describing sounds normal. RPM's stand for revolutions per minute. Each minute your engine is running, the pistons are going up and down. When you are not going anywhere, your engine is idling and so the RPM's should NOT be very high. However, when you race up a hill, your RPM's SHOULD be high because your engine has to work hard to climb the hill or to go fast.
Idle speed= 650 Revolutions Per Minute. That means your engine cylinders each work 650 times in One minute.
At freeway speeds, your engine will revolve somewhere between 1600 and 2100 times per minute. I hope that helps.

Losing power going up hills

sounds pretty normal. what speed do you try out the passing gear? anything above 35-45 mph and it will feel like neutral. Passing gear is actually only 1st gear. When you press down the pedal, it forces the transmisson to shift into low gear.

2002 Santa Fe 127174 miles. On hills car slows dwn, rpm is climbing, speed is droping. on steep hills from a dead stop rpm's are 4,000 speed is just below 20mph. have had the fluid flushed twice.

sounds like your transmission is going bad fast. get it checked asap to see if it can still be saved. aamco will take a look at it. if its completely bad, then getting a new transmission might be cheaper than getting the current one fixed so look into that!!

Can i shift the gear immediately while climbing on a high roads from high speed to low speed on a automatic transmission 1996 honda civic vti vtec? Do i need to brake first the engine before i will shift...

That is not recommended, as it could cause transmission damage. Since you have a VTEC you should get a power boost at around 5000 rpm which should make climbing hills easier and not need a shift of the transmission.

My Sonata GL is at 105K; in the maintenance schedule it is recommended to replace the timing belt. 1) If this particular belt breaks what would be the damage? 2) How much leeway do I have, eg.:100 miles,...

Timing belts are typically only used on overhead camshaft engines. Timing belts are used to synchronize the crankshaft with the camshaft, similar to a timing chain on an overhead valve (pushrod) engine. Unlike a timing belt, a timing chain will normally last the life of the engine without needing service or replacement. Timing belts use raised teeth to mesh with sprockets to operate the valvetrain of an overhead camshaft engine.

Whenever a vehicle with an unknown service history comes into your repair facility or is recently purchased, here are some points that should be asked to help prevent costly engine damage:

* Does the owner know if, or when the belt was replaced-
* If the vehicle purchased is used, or the condition and mileage of the last timing belt replacement are unknown, it is recommended to inspect, replace or at least inform the owner that the vehicle is equipped with a timing belt.
* Note the mileage of the vehicle. The average replacement interval for a timing belt is approximately 60,000 miles (96,000 km).


Inspect the drive belt for signs of glazing or cracking. A glazed belt will be perfectly smooth from slippage, while a good belt will have a slight texture of fabric visible. Cracks will usually start at the inner edge of the belt and run outward. All worn or damaged drive belts should be replaced immediately.

Removal & Installation

1. Raise and support the vehicle.
2. Remove the engine splash shield.
3. Rotate the drive belt tensioner clockwise to release the drive belt tension.
4. Remove the drive belt from the alternator.
5. Slowly release the drive belt tensioner.
6. Remove the drive belt from the accessory drive pulleys.


Fig. Accessory drive belt routing - 2.4L engines

To install:

1. Install the drive belt to the accessory drive pulley.
2. Rotate the drive belt tensioner clockwise.
3. Install the drive belt to the alternator.
4. Ensure the drive belt is properly aligned and seated into the grooves of the accessory drive pulleys.
5. Slowly release the drive belt tensioner
6. Install the engine splash shield.
7. Lower the vehicle.

Hope helps.
