Rover 75 engine problems

Hi all,

I've been having a few issues with my 2004 Rover 75 Connoisseur as of late and figured this is the best place to go to.

Basically, the engine has a heating problem due to poor water circulation. After numerous trips to a local mechanic who tried whatever he could think of, the situation was stable for a while but has gone bad again. Furthermore, I think the car isn't firing on all cylinders now, and is really lacking in power.

After doing a bit of research I found out that diesel engines in a 75 are better than petrol engines, which is what I have. So I'm thinking of replacing the engine altogether, and was looking for advice on this topic.

Please excuse my lack of mechanical terminology as I am really a newbie at this stuff (only had the car for a year!)

Thanks in advance.

You are correct, the Diesels are far superior to the petrols.... (totally unbias of course)....

If you search the forums there is a lot of information about thermostats which I think may be the root of your problem.....

This thread maybe of some interest to you ;)

Anything is possible but you will be stripping out and rebuilding shed loads on the car. :getmecoat:

If you want a diesel then best go and buy one. ;)

Start by telling us which engine you have, and tell us exactly what problem you are experiencing. Add to that what has been done to rectify it, and it is possible that you will get an intelligent reply. :D

His profile states he has a 1.8

Hello Muhammad and :welcome: to the club. You've come to the right place.

That's a common complaint with all the 75/ZT engines and is often repairable easily and cheaply, if you know where to look! :}
Please tell us exactly what caused you to consult a mechanic. Is coolant being ejected through the expansion tank cap? Is the temperature gauge shooting up to maximum? Give us as much detail as you can.

If by "better" you mean more reliable, then take a look at the threads in this technical section posted over the past few months. Count how many complaints there are of diesels failing to start, heaters not working (in the winter, of course) and crankshaft pulleys disintegrating, to say nothing of fuel pump failure which is very common.

No-one wants to start a contest on petrol versus diesel so let's just say that both engine designs have their own advantages and disadvantages. Forget your idea of changing engine types. We can most likely guide you to an effective solution for your heating problems, so tell us all about it!

No the diesel is not superior to the petrol, having driven nearly 9000 miles in the past 3 months in the ZT, I got into Frosty this morning took him for a run and what a quiet refined chap he really is :drool4:

Hi Simon,

Thanks for your reply, definitely helped.

I consulted the mechanic after noticing that the fuel gauge was going way to high for regular town driving and that there was steam coming from under the bonnet. Usually there is no coolant being expelled, however, after letting the car cool down if you open the cap then it all gushes out. After the initial consultation, the mechanic told me that there was a problem with the water circulation and did the following to rectify them;

1. replaced head gasket
2. fixed a leak in a pipe right behind the radiator grille
3. replaced the fan with a higher power one

I was looking at replacing the engine as a last resort as I REALLY love my car and would do anything to keep it, so if you guys could help me fix this, I'd be eternally greatful.

Hope thats enough detail, if not please ask for more and I'll be on the phone to the mechanic.

Hi kaiser,

I currently have a 1.8L petrol engine in my 2004 Rover 75 Connoisseur

The problem is that the temperature gauge goes very high very easily.

To rectify the problem, the head gasket has been changed, a new fan fitted and a leak fixed in a pipe near the radiator grille.

Thanks again
