Antifreeze/Coolant type?
I have a new to me 2006 lr3 V8 that needs the coolant topped off. I was wondering what type of coolant to use, just dexcool or something else? I live almost 2 hours from a dealer so I really don't want to drive that distance for coolant if I can just buy some at a auto parts store.

LR3 uses dexcool. I've not heard of any problems with the crusting up like the D2, so most people just continue to use the dexcool. I have read some stuff about heater cores getting partially blocked, but I don't know if it's related or not.
How many miles are on it? If it's got quite a few, then it might be time to flush anyway, and maybe you could use something else in it. But just topping off, I'd used dexcool. |
It has 93,000 miles since I have owned it I have done transmission fluid/pan change, new diff fluid(lucky me I have rear locker), transfer case fluid, all new filters, new break light switch, used sea foam once and always put premium fuel in it. I am going to do a oil change this week with castrol edge, wix filter and use the BG EPR & MOA kit as well.

Chevron Texaco Havoline XLC coolant, orange in colour.
The LR recommended coolant is Chevron Texaco Havoline XLC, the orange coloured stuff.
Below is from a Chevron product brochure. Note that the Chevron XLC meets GMs DexCool specs but I am not convinced that putting GM DexCool in your aluminum engine is quite the same thing. What you are really after is corrosion protection. Yes, freeze up in the winter matters but what you really want is corrosion free heater cores and open engine block channels not plugged with the results of corrosion. Rather than just topping up, you might consider a total empty and refill with new fluid in order to renew the corrosion resistance of the fluid. A maximum of five years or 150,000 miles is all Chevron thinks their fluid is good for. DELO is Chevron's trade name in North America of the XLC. Below is a link to a product page. https://cglapps.chevron.com/msdspds/...&docFormat=PDF Below is the product description for the Caltex Havoline XLC, the same as the DELO stuff. Description Havoline Extended Life Antifreeze Coolant (XLC) is a cooling fluid and corrosion inhibitor for combustion engines and heat transfer systems. Havoline XLC is an ethylene glycol-based fluid that provides maintenance-free protection against freezing, boiling and corrosion. With patented silicate-free aliphatic acid technology, Havoline XLC provides long-life corrosion protection for all engine metals, including aluminum and ferrous alloys. During extensive fleet testing Havoline XLC has proven to provide protection for at least 32,000 hours. Typical Characteristics Code 030379 (7994) Ash content, mass %, ASTM D 1119 1.1 Nitrite, amine, phosphate, borate, silicate Nil Color: Orange Density at 20°C, kg/l, ASTM D 1122 1.113 Equilibrium boiling point, °C, ASTM D 1120 172 Reserve alkalinity (pH 4.5), ASTM D 1121 20.4 Storage stability at 20°C 3 years 50% dilution 33% dilution pH, ASTM D1287 — 8.3 Foaming at 25°C, break time, sec., ASTM D 1881 5 — Freeze protection, °C –40 –20 Effect on non-metals, GME 60 255 None None Staining characteristics, ASTM D 1882 — None Hard water stability, VW PV 1426 No precipitate — Recommended Uses Havoline XLC provides long-life freeze and corrosion protection. To ensure good corrosion protection it is recommended to use at least 33 volume percent of Havoline XLC in solution. Havoline XLC may be used in engines manufactured from cast iron, aluminum or a combination of the two metals, and in cooling systems made of aluminum or copper alloys. Havoline XLC is compatible with most other ethylene glycol-based cooling water treatments. The use of soft water is preferred for dilution, though lab testing has shown that acceptable corrosion results are still obtained with water of 20°dH, containing up to 500 ppm chlorides and 500 ppm sulphates. Havoline XLC has been approved by the following engine builders: Deutz/MWM (0199-2091), MAN Diesel (D36 5600), Wärtsilä Switzerland, Rolls-Royce (2.13.01), Wärtsilä Finland (32-9011) and Caterpillar-MaK (A4.05.09.02). Havoline XLC meets or exceeds the following specifications: ASTM D3306 and D4656/4985, BS 6580, and NATO S-759. Performance Benefits 1. Environment The carboxylic acids are environmentally friendly. 2. Corrosion Protection Provides long-life protection against all forms of corrosion on all metals including the aluminum heat transfer surfaces contained in modern engines. 3. Cavitation Protection Offers excellent cavitation protection without using nitrite or nitrite-based supplemental coolant additives (SCAs). 4. Seal Compatibility Has no adverse effect on rubber hoses and gasket materials as shown in testing a wide range of seal materials. 5. Heat Transfer Efficiency The carboxylic acid inhibitor forms a single layer of protective molecules on the metal surfaces, thus providing a very efficient heat transfer. 6. Economics Corrosion protection and low additive depletion results in less maintenance and repair costs. |
The Land Rover dealer will put dexcool in your 3 if it's out of warranty, I've heard that from a tech. He said they only use the Land Rover bottles for stuff that's is being paid for by Land Rover.
But if it makes you feel better, I buy havoline brand dexcool ;-) |
a bit like the tranny oil
Yes, the coolant spec is a bit like the tranny oil spec concern.
Given that Ford now installs license built ZF tranny's in most of their vehicles, it seems to me that the half price Ford tranny oil should be fine as well. Re the coolant, I think the question is one of the design of the corrosion inhibitors. I think that is what the words "silicate free" are all about. How it is that Land Rover always seems to somehow incorporate some twist in every design such that norms seem not to prevail always puzzles me. As such, I think the colour thing, orange, matters as I expect the manufacturer is trying to tell us something - and yes, I am happier with the word Havoline. Thanks for the reply. Of course, the bigger problem with the cooling system is how to get the air out so that one does not melt the aluminum due to air locks. Given the number of little hoses in the cooling system, I guess that is why it air locks seemingly everywhere and just not at the heater cores. |
Dex-cool Zerex what my dealer sells , if they run out of oem fluid.

Yes, Zerex is probably OK.
I actually think the Zerex brand coolant is OK.
I see per the link below that Valvoline mentions that Zerex is both phosphate and silicate free. When ones clicks on the FAQ links within, they have a interesting comment on mixing of different brands of fluids. Colour they say in a qualified manner, does not matter, (assuming the colour is not green or yellow per below), but composition does. Organic seems to be the magic word. https://valvoline.com/products/consu.../antifreeze/41 ZEREX™ DEX-COOL® antifreeze coolant contains no phosphates, silicates, borates, nitrates, amines and nitrites. Its global formulation meets the phosphate-free requirements of European automobile manufacturers and the silicate free requirement of Asian automobile manufacturers like Toyota, Scion, Acura, Hyundai, Kia, Honda, Isuzu and others. It can be mixed with any DEX-COOL® and is approved by Opel, Dae Woo and Saab. It is dyed orange to distinguish its unique chemistry from traditional green and yellow silicate coolants. |
Thank you guys for the replys, I ended up using Zerex Dex-cool on the back of the bottle it did show that it was safe for Rovers. I do plan on doing a flush in the near future though.

appreciate the post
Thanks for letting us know.
I will find a jug and read the back of it as well. |
