I finally have no lights on the dash. unbelievable. knock on wood.

Was getting a P1415 I could not chase to save my life. Did the Hyundai valve, the chased lines and SAI valves, replaced the SAI pump. Which is much quieter now. The trick was the little valve next to the Hyundai valve. The rover one was ~$50, strangely, the BMW one was $20. BMW, Land Rover Vacuum Control Valve - PIERBURG - 7.02318.01.0 - NEW OEM
Credit to Rover Master, the guy who pinned my cylinders and did some other work. If you need anything done outside of your DIY scope, totally worth getting the truck to him. Super knowledgeable.

Replaced the ABS pump, got rid of my four Amigos. That is nice. Knock on wood again.

I have a set of 2" lift spaces that I am going to install next time we have warm day, looks like a pretty simple install.

 

@mln01 - My temps are usually in the low 190's but when I get on the highway at those speeds, I'm usually up around 215-217. What have you done to your rig to run it at such low temps? Do you still have the stock air scoop under the front bumper?

 

bought a genuine 180 thermostat from lucky 8. Replaced fan clutch and radiator. Cruising temp is 188.6 and at idle usually 194-203 havnt seen over 205 yet.

 

I've got an inline thermostat and rarely see above 200 even on the highway at 75-80 unless it's really warm out.

 

My 03 ls swap sat in my backyard for about a year due to me away for work. When i got back rats have somehow got inside and destroyed everything from seats to multiple harnesses. So i bought an 04 to replace it and currently on the process taking the good parts ot in order to swap em over.

 

I did that too but I used a cheap amazon radiator core. Does the mfg of the radiator make a difference?

 

hmmm i have a nissen radiator. Seems to be working very well. Would also think about water pump idlf havnt changed yet

 

Generally, no, although some guys have had bad radiators out of the box. Very rare, maybe two that I know of based on helping people with their cooling problems over the last couple of years (several hundred inline installations and follow up assistance). More likely your thermostat is not functioning ideally, I have several working factory thermostats (I think one is brand new never been used) I can send for the cost of shipping but obviously I recommend the inline mod. Several users down in your part of the world can give you their feedback but generally you should be seeing 100 degrees + ambient as operating temperature.

 

My truck has the stock cooling system setup, but with the Land Rover genuine, gray 180°F soft spring thermostat (part #PEL500110) bought in Feb 2016 from bputah.com. Nothing special. I had to replace the water pump two years ago this month, and when I did that I also replaced the fan clutch with the Hayden 2991 (Severe Duty). Stock air intake (from under the wing (fender), not under the bumper).

Cruising temp is 188.6°F as displayed via the UltraGauge, sometimes dipping a bit lower. Temps at idle climb to the mid to upper 190s, and very rarely a bit over 200. What's odd is that the idle temps are a few degrees higher than they were with the stock fan clutch. One of these days I may reinstall the stock fan clutch and see what happens with the idle temps.

It's weird that the temps for your truck climb at highway speeds. The norm is that temps go down with more air moving through the radiator while the vehicle is moving than is supplied by the fan at idle.

 

@mln01 Mine will sit at 183 all day (inline) at around 70 to 100F ambient under or at 40 mph and cruising. Accelerating medium to hard will run me up to 188 to 194ish, as will climbing steep hills at those speeds. My bet is the AC condenser fins are partly clogged reducing airflow or the Transmission cooler, other that the that and the water pump my cooling system is new.

I noticed a significant temp drop after going down at flood roaded (500M) at 2500 rpm. As the water crested my hood the engine temp dropped 10 degrees with in seconds it was very significant. Most of that water would hit the condenser and oil sump so that leads me to those 2 things.
