    First things first. New water pump, new thermostat housing, new over fill hose, and rear heater core pipe all have been installed. I cannot, repeat cannot figure out why my coolant (at this point just distilled water) isn’t circulating. I get a weird noise and performance restriction pop up...

    Hello I have an 04 Range Rover. Recently my coolant recovery tank developed a crack and leaked out all the coolant. I had to drive it 10 mins to get it home in that condition. I did fill it on the way, but it still leaked out. Once I replaced the tank and refilled it with coolant I got stuck...

    Hi All, Hoping someone here could help me with this. For the sake of not starting yet another Overheating thread, I'll cut to the chase here. My 95 LWB started overheating very suddenly the other day during a normal drive on flat roads in cool weather. All visual stuff recommended on this...

    Hi Everyone, I had a shop replace the thermostat in my 2006 Range Rover Supercharged. 144k miles on the vehicle. Fault codes prior to dropping it off were P0171, P0174 and P0128. Shop replaced the thermostat ($560 total) and stated when they performed a test drive P0128 came back. They...

    I have replaced my water pump, thermostat, thermostat housing, ignition coils and plugs. I start to drive and thermostat does not open until gauge pegs hot. This causes back pressure where coolant is forced out of cap at reservoir. No signs of coolant in oil or in cylinders.(I pulled plugs to...

    I wanted y'all to know. Last year I replace the radiator, water pump and thermostat on my 98 RR. I used all the orginal hose clamps except for one. For the last week or two I noticed the water in the overflow tank was about 8ozs low. A little less than a bottle of spring water.Every other I...

    Last year my previous P38 was written off in an accident and I have finally bought another one that I like - '96 and only 64K kilometers. It has developed an overheating problem. I changed the fan hub but no improvement. I removed the thermostat and put in a new one - that was even worse. I...

    I've put a new thermostat in to cure the engine not getting up to temperature. I've bled the system as best I can and according to RAVE, but I've obviously got air in the lower half of the thermostat. As such, it's not getting hot enough to open. The gauge is getting up to the middle quite...

    I was getting CEL fault P0128. Replaced the thermostat but still getting the same code on a regular basis. Picked up the hose thermostat (PCH501310G) and wondered if anyone else has done that as a DIY project. If so, any helpful tips, specific tools or unexpected surprises? thanks in advance.

    I have a check engine light and three codes that I have erased a few times but they keep coming back. Two of them are are 02 sensor bank 1 and 2, downstream. So, I removed the rear most 02 sensors and cleaned them and reinstalled. I figured I have nothing to lose by trying that. I will order...

    Hi folks, my first post after having used this source of wisdom for a while. So I am a bit concerned: I started up my engine yesterday (cold start, night time temperature approx 10 degrees Celsius ) and after 10 seconds or so engine oil started to ooze out of the oil filter housing, at the...

    I have had a 1996 Petrol HSE AUTO since February 2000 and always looked after it. Yesterday I had the radiator replaced and when the vehicle was returned the book and exclamation mark symbols were on and the aircon was running ambient. Thee was no book or exclamation mark symbols when I took the...

    Just bought a 2004 l322 4.4 v8 RR . I expected to need a gearbox but sorted that issue with a filter and oil change then hit the real problem- down compression on 2 cylinders. Looked into the block with a Nora scope and the notes were badly scored so sourced an engine and have fitttd it. While...

    I did oil change today and noticed some dryed coolant residue around the thermostat body (2006 hse). I replaced coolant tee a couple of years ago ... so I’m thinking the plastic thermostat body is cracked/leaking under pressure ? If there is any coolant loss ... it is minor (the reservoir is a...
