1998 Opel Vectra 2.0 litre ecotech engine


GM made a lemon and they know it!


The engine overheats all the time!

The timing belt broke!

Under chassis noises.

Very poor re-sale value!

General Comments:

If GM wants to stay in the car manufacturing business they should start firing those people who approved the quality of the timing belts, suspension design and cooling system design! They should understand that the cars they are selling are not only sold in Europe where climate is cool and streets and highways are paved very well. My country has highways in which you can play mini golf and the heat reaches from 30 to 38 degrees Celsius!

The design of the car from the exterior and interior point of view is quite good and sometimes an eye catcher! However, if GM refuses to understand the meaning of "quality" then they should pack-up and leave!

Would you buy another car from this manufacturer? No

About the overheating: U are right, but, there is a possibility to replace the heat sensor under the head and replace it with another one with different characteristic. Ask your Opel dealer which one of the two available types should be better for your weather conditions.

This was a follow up regarding my OPEL VECTRA 2.5 V6 automatic made in the Philippines, (spelling as seen at the back of the trunk) Regarding the overheating, thanks God! re the problem was solve. Hence there was a wrong installation of the auxiliary fan that was inverted, what the electrician did both the radiator fan and the auxilary was facing towards the engine already. We did a total re-wiring gauge #18 for the radiator fan and auxiliary, we add a fuses, socket relay. So today my overheating is gone.

A cold blooded car which is afraid of the sun


It is such a good car except that our climate here in the Philippines, during summer, reaches 34 degrees centigrade. Current models have been advertised to have an Asian driving package, but my particular model has problems with overheating which, in turn, caused problems with the air-conditioning and idling. In short, the car overheats and stalls in traffic. It has been an inherent problem ever since I got the car. The mechanics at the dealership simply refuse to acknowledge that the main cause of the problem is with the thermostat spring of the TV TCP (Thermostat Control Valve). It is set to 100 degrees Fahrenheit which is almost too late to cool the engine circulation. In temperate countries, this would be a perfect setting, but in tropical countries, this would simply be disastrous.

There was also a problem with the automatic transmission lever which jarred everytime it shifted. The dealer replaced it only after 21,000 km and fortunately it was still under warranty.

Then came the problem with the suspension which had a loud clanking sound. The roads in the city are not exactly prime. There are a lot of undulations as a result of the asphalt giving in to large loads and high temperature. Every time I go over those undulations, I would hear a clunking sound which is chassis or suspension related. They have changed the rubber suspension boots, but to no avail. The problem is still there and I think is more of a design problem than anything else.

My previous car, which was a Nissan Cefiro is still with me, but my wife is the one driving it and it does not have a single problem. The dual independent radiators handle our tropical climate with kid gloves. I hope that the dealership solves the problems soon. I have been an Opel fan since the days of the Opel Manta and Opel Ascona (which were both my previous cars). I just hope that Opel still has the same quality which it did with their previous cars and not suffer a heat stroke.

General Comments:

This car is suited for cold climates, but once exposed to the tropics, suffers a heat stroke.

A lot of the problems mentioned here aren't heat related at all, but rather manufacturing faults.

I'm from New Zealand I have a Vectra as well. The problem might be because of humidity and high temperature. My car did overheat in a traffic jam once because of high humidity and temperature.
