Popped the coolant reservoir cap the other day and sprayed coolant everywhere. I was able to remove the threaded section inside the pipe and replaced the cap and o-ring. Refilled the coolant but my truck is overheating. Any ideas what might be causing it? The truck was running perfectly...

Hey everyone, I just received my 1995 defender 130 tdi. while driving on the free way yesterday all of a sudden i lost power mid drive and it died on the side of the freeway. I was able to start again after cooling down but it was having struggles starting and idling. When it was running the...

So I've installed the 300 in my Series 2a coiler project and the radiator is custom mounted. Things are tight and I'm working on the radiator hoses now. I'm wondering if the expansion tank connection has to be down low or not as indicated in the diagram? It would be pretty ease (and would...

I’ve been trying to chase down what’s was seemingly a sporadically occurring coolant leak on my 300tdi. The engine had a new head and head gasket installed (by me) just under a year ago. It also has a new expansion tank cap (I know these aren’t always calibrated properly) Over the course...

Hey everyone Due to Defendersource's search function being somewhat broken, verticalscope being unable to get past their IT subcontractor to fix it, and Google not being able to index this site properly either, I can't seem to find a very recent discussion about the Range Rover PRC7925 Coolant...

Anyone wire a coolant level warning sensor in the black coolant reservoir? Saw a thread where someone used a cap from a Range Rover but to wire that up to a light was complicated

Issue: Temp gauge bottomed out on "C" at all times Knowns: 1) Gauge does not move from rest under any driving/temp conditions, not even a bump 2) Wire to bullet connector thermistor on intake manifold is getting between 9.5-10v from gauge 3) when wire to thermistor is grounded out, gauge does...

Hello Dear Gentlemen; Would you tell me how I can connect the PRC 7925 (Range Rover Classic Sensor Low Level Coolant) to my Tdi 300 (1998 model Td5 dash board). I found some explanation on internet but İt is needed to have or to build some interface such as relay, resistor (electronical...

For those using a MadMan EMS2, what did you program your coolant temp settings to? I'm using the EMS2 to trigger an electric fan, which works great, but I stupidly set it to come on at 80 (the correct temp in Celsius not Fahrenheit). I sorta crapped my pants when the fan kicked on, then the...

Hi all, Took my project for the first spin around the block in 2.5 years. This was the first time it's ever been driven with the new powerplant besides being loaded on/off the trailer for paint. Observations: Coolant temps seem to operate around 185F when cruising 30-40mph. Oil temperatures...

Any recommendations on coolant type/brand for a 95 NAS 3.9L? What's everyone using & keeping on hand? Thanks.

Does anybody have a cooling system diagram on the 3.5L V8? I'm swapping to an edelbrock set up and in the process found that the heater core had been bypassed at the back of the engine. It looks like one port on the water pump goes through the manifold and the other goes through the pipe on...

I replaced my water pump; however, two on the long bolts the pass through the water pump, timing cover and into the block were leaking coolant. These two bolts break into the water jacket. I cleaned the threads both block and bolts, applied high temp thread thread sealant , allowed 48 hours to...

I replaced my 2.5TD with a Discovery 200tdi. The coolant temperature gauge is the original from the 2.5TD. I replaced the sender on the Discovery 200TDI with PRC6663. This has a 5/8" with a fine thread. When the engine heats up it reads within the white band but at the high end...

Hello, Long time Series IIA daily driver that now has a kid so I had to get a family car. Picked up a 1991 Range Rover classic with a 300tdi. My first diesel, so far so good. Lots of little electrical things to sort out but I'm searching for ground wires to see if that clears up any of my...

So...the 300tdi blew a freeze plug a few weeks ago. Replaced that. Pressurized the system to 30psi, it held that. All seemed fine regarding that. Couldn't get the engine to go above 40-50 F and the air was warm from the heater. It was also 20 F outside. Replaced the thermostat with one that...

I have a 2002 110 with TD5 that oil is entering the coolant reservoir. My first thought was blown head gasket and it may be but it doesn't show the characteristics I would think it would. Any ideas of what might be the problem?, I'am in Mexico and no one is familiar with the TD5 because they...

Hi all, I noticed on my last trip that I had a coolant leak. after about 700 mile in 1 day, my coolant level was down about about 1/2L. I topped it up. Oddly, on the 700mi drive back home, there was no noticeable top off needed. At first, I thought it was the water pump, but the leak (more...
