Sometimes, the bloody obvious can get overlooked!
This is project 14, the 2.5 Elite bought last week. Main problem - chronic overheating. Basically runs at 95 all day until you slow down then goes way over 100!!!! Not good. In view of the previously done oil cooler, decided to remove and flush radiator. As I had a known good spare radiatior I fitted that one to save time after flushing the system thoroughly. Observed that the aircon rad was a bit green looking.
Anyway, problem still there. next port of call was the water pump which was leaking slightly. May as well do the cambelt at the same time.
So, this morning stripped out the radiator again, removed the air con rad to see that it was fairly blocked airwise with green gunge from a leak. Cleaned up the area and enjoyed the huge space gained to work in. A tip here guys, remove the air filter box when working on aux tensioner. It makes access a huge amount better.
Then me and Laidback removed all the cambelt access stuff and agreed that the water pump looked f-f-f-f-f-f-f-f- not very good. Close inspection of the cambelt revealed that it was almost brand new and the tensioners too. So that stayed put after confirming the timing was spot on.
Water pump off and reveals that the seal had dislodged and partially disintigrated. So, new pump on and rebuild, confident that it would all be fine now.
Sat with the engine running and it sat at 95 degrees. Great. Off for a run. Overheating the same with the fan cutting in at about 99 degrees.
Me and Laidback were talking at some length about possible blockages, thermostats, thermo switches, extra fans blah blah. I said that I had a spare speedo pod and would swap it just to rule out the gauge giving us false alarms. You can guess what can't you? It was. Changed the pod and the temperature is spot on normal again. Changed it back and it 'says' overheating, change back again and its all fine.
So, this major fault was nothing more than the guage itself. The car will no doubt benefit from the newer radiator and the coolant flush. And the pump was definitely cacked. But this just shows how the blindingly obvious can sometimes be just that!
Total work about 3 days. Total job? 10 minutes!!!

Glad you've got it sorted though. [smiley=thumbsup.gif]

You'll feel better knowing that whoever you flog it to is getting a goodun ;)
-
Don't you just hate it when that happens. At least you fixed a few other problems looking for the real fault.
-
Weird eh - glad it's sorted
-
Yeah m8 well done on getting it sorted

McB..I assume the green gunge was aircon dye?
How exactly does your faulty temp gauge lead to my project car losing its water filler cap????
On top of that was nigsey1600e calling in to Marks to have his multirams doctored and suddenly Im missing a vacuum solenoid.
By the time I get the motor fixed there wont be a car left to put it in at this rate. :D
PS I could do with a n/s rear light cluster if you see one, I have seen a crack, and no it wasnt Marks shorts falling down again.
-
LOL!!!! ;D
Yes, the filler cap was an emergency fix - sorry. I have yours in the boot and will be taking it back today. Vacuum pipe - not me mate?
NSR light cluster - estate?
Green gunge was a mixture of aircon dye and dirt. Makes a nice paste that is perfect for blocking air passage.

Sometime's you can't see the wood for the trees!!!!!!!!! :-/

Yes....estate....Pete kicked it in a fit of rage when he noticed his coolant cap missing ;)
-
Erm........... Ooooooops. It wasn't me. i wasn't there. i didn't do it. It was that other bloke, hang on..... who's not online.......... Laidback. yes, it was him. honestly. he'll deny it of course...... ;D
-
It's ok we beleive you ;) ;) ;)

ah that doesnt mean i was right does it? oh no now im afraid very afraid because by that token my timing is out, the cars clocked, and the wifes nissan is a ringer............
