    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

    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...

    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...

    This is the diesel version. I bought this with the intent to install it in my truck. I paid $539.99 + shipping for the kit off ebay when they were on super sale or something. This is the cheapest you can generally find these for. The kit is usually around $700+. I opened the box, read the...

    I am planning to add an Airtop heater to the interior of the 110. I currently have a coolant heater under the hood that has a diesel line from the tank to the heater. I would like to T in the diesel line for the Airtop from this line. Is there any reason I shouldn't do this? Does each unit need...
