Mixed opinions on Range rover problem....

A So-called british car specialist looked att he overheating problem on the range rover. He claims its a cracked block.

I had him run a block test, and the fluid did not change to yellow as he stated it should if there was exhaust gas in the coolant.

I then took it to our trusted independent who does work on my brothers range rover all the time, and we ran the test 6 times, and the fluid did not change color to yellow.

He believes as do I that the radiator is clogged up.

I am pulling the radiator to have it rebuilt. If that doesn't cure the problem, then I will suspect a problem with the block.

There is no coolant smell coming fromt he exhaust, and no exhaust odor in the coolant tank.

The cooling system just has too much pressure. I suspect that a clog in the radiator is forcing the waterpump to pump harder to get the water flwoing.

BTW, I drove the car all day today, and it did not run past halfway on the temp gauge. I even had the temp read with a temperature measuring gun, and it topped at 150 degrees F. this is not very hot, and in conversion I believe is around 80-90 degrees C.

We tested temp all over the engine and radiator, and we found nothing over 150 at all.

The british specialist probably makes most of his living, pulling good engines claiming they are bad, selling a used engine to the unsuspecting owner, then selling their engine to some other unsuspecting owner. They claimed we replace several of these engines a month.

Now they did have a car with a cracked block, a defender 90 with 54k ont he odo and a cracked block. I watched them do the block test on it, and the fluid turned yellow almost instantly.

We tested at the other mechanic and let the fluid sit there for 10 minutes without a color change.

I'll let you all know what the radiator shop finds.

I'm going to flush the block once the radiator is out.

I may even put in a transmission oil cooler too just for safety. They arent expensive and should be good for the car.

My father just looked at a 97 Range Roiver 4.6 HSE with 98k on it, the car is 100% perfect in every way and needs onlya few minor things that will be covered by the owner of the vehicle as he still has a warranty on the car for another 3k.

If all goes well, my dad will have a 4.6 HSe in his stable.
