Thread: My 86 Rangie Hiline

"When in doubt, fat side out"

So, after around 2 years sitting doing nothing I thought I’d dust of the Rangie and see if I could get to the bottom of an occasional overheating issue. I’ve got more of a run down in the build thread but couldn’t find that on my phone to link. Basically intermittent temp rise - I’ve always shut it down well before 100 (on a VDO gauge not the dash) and it does it only here and there with no similarities. The rad is good and was rodded before I installed it with new thermostat and hoses - all done by the PO who I know and the Disco was a good runner without these issues prior to it being wrecked. Pulled the water pump today and that was toast although not leaking, but bearings was rough and movement on the shaft so it’s amazing it didn’t leak to be honest, but what I did find was the whatever it is in the pic attached. Anyone got any ideas? It was jammed in the inlet on an angle and almost completely blocking the inlet to the pump. No idea why it’s there or where it may have come from. Someone in the other thread said I might have something wandering around the coolant system and this is certainly that.

Another issue that’s ongoing is that it’s hard to start when cold - eventually catches and once running it’s fine and easy to start after that for several hours. Thinking one of the temp sensors giving the ECU incorrect info? There was a good troubleshooting page on another forum for the 14CUX system but I can’t seem to find it now. Any other ideas?

Appreciate any and all info as usual. [emoIMG_2866.jpgji4]

Have a look and see if the fuel rail temp sender is plugged in. I reckon this impacts the starting of them....... (When thought I was having issues with mine, I googled it, apparently its there for hot starts, if the fuel rail is hot ... and possilby boiling it causes the injectors to cycle and somehow clear any vapour locks). I'm betting it also is used for cold starts.

Here's another thought though. I'm wondering if its needing to lift fuel from the tank (like an old carby car that has drained off before it'll start). Try cycling the key a dozen times before you cold start it and see if it makes a diference. If it does, the fuel is draining back to the tank .... and the pump maybe weak.

That broken off hose end is amazing! You'd have never figured that one out without stripping everything down.

I was about to suggest checking the temperature gauge until I read to that bit. Years ago my old Citroen CX drove me bat**** crazy .... I could barely drive it across town without the temperature spiking. I had the radiator rodded at two different places, pulled down and checked the water pump .... checked the fans, made sure they were spinning the wrong way. But the issue persisted making the car unusable. The car is true 80's .... tacky looking digital display in the center of the dash with 100% accurate temperature gauge, oil temperature gauge, outside temperature gauge and trip computer in a housing. I was sitting in traffic one lunchtime and was watching the gauges like a hawk .... They aren't normalised and show the true temperature to the degreee. They were very long traffic lights, I heard the radiator fans come on at low speed ( 88degrees ) and cycle back off ( 82 degrees ) ..... the only thing was it was the oil temperature gauge showing this .................... I had hooked up the connectors on the back of the motor backwards when I was tidying up the wiring a couple months before hand. I'd plugged the oil temp and coolant temp in backwards. So everytime I, er, "exercised" the turbo, the oil temperature would obviously spike heavily ......... but this was showing on the coolant temperature gauge I can "almost" laugh about now ... many years later

Here is another link. Similar but some items better described:

Lucas 14CUX Fuel Injection System – Installation and Diagnostic Notes. - ACT Performance Products - your source for after market TVR upgrades, components and performance accessories.

Is this a Disco engine in your RR, or just the radiator?

I chased reluctant starting for several years with my 1997 3.9 EFI and eventually changed out the ignition module which, cured it. I have lost track of how many replacement fuel pumps that it has had, but they have always failed completely. There is a shrader valve on the fuel rail to check the pressure, but even a bit down on pressure will not bother them.

Complete Disco engine, auto and radiator.

So has anyone got any ideas as to what the bit in the pic is and why it would be in the cooling system?

It appears to be some form of hose nipple. Is it metal or plastic? Done several of these engines and dont recall seeing anything like that.
But I do recall that just recently there was a post, I think it was on here, showing a similar item found in I believe a tdi engine?
