Hi all.
Having recently found a leak on the alloy radiator in my Chimaera, I took Davetripletvr's advice and contacted Radtec direct to investigate the possibility of having it repaired.
I took the radiator over personally and met with Darren who owns the company. He is a very friendly chap and even showed me round the workshop where amongst other things was an EVO rally car that they were making parts for. Apparently they are OE equopment suppliers to Koenig so the credentials are good!
Darren agreed to test the radiator so I left it with him. I duly received a call to say that it was leaking!
In Darrens opinion it would be better to fit a new radiator rather than repair the existing one and he offered me one at a price I could not refuse! I now have a shiny new radiator waiting to be fitted.....
I cannot praise the company highly enough. the radiator was fitted by the previous owner 2 1/2 years ago and although it had only covered 3.5K Radtec had no obligation to help me in any way so I was very pleased with the outcome to say the least.
One interesting point to note though.... When previously fitted, the cooling system was filled with pink antifreeze. Darren recommends the use of blue ethylene glycol in aluminium radiators as apparently the corrosion inhibitors in the pink formulas are not as good. Any thoughts on this?
In these days where we only hear about the bad companies out there I thought it would be nice to relate a good one to you!
Regards Chris.

- It works
- It's cheap
- I change ever 2 years
As it happens I recently did one of my scheduled changes changes at the weekend, and in went five litres of ScrewFix's 'Every Day' blue concentrate.
At £2.70 for 5lt of distilled water and a tenner for the Glycol buys you 10 litres of quality API standard coolant for £12.70, and you're still left wit some extra over

.
Job done!
People rely on experts to advise them, trouble is experts have different opinions.
As my RV8 came with blue I've always assumed it should stay blue more than anything to do with the rad but I'm happy to be corrected.
Mines got another year before I drain it so I'll look into the differences in the two products.

There's lots of different coolants available now (just by colour there's red, pink, orange, green *...) and it's important to use the correct type for the mix of metals and 'rubber' hoses and seals it comes into contact with.
It's comparable to the oil question, we've moved on from mineral oils to synthetics. Blue antifreeze is considered rather 'stone age', but then... so is the RV8
Interestingly the Comma website lists G48 for the 90's Range Rovers so you should possibly be using that, which is green...
The really important thing is not to mix them, you'll end up with what looks like white fatty globules floating around in it.

I've recently had the same experience. My Radtec twin core radiator started leaking, it was about 5 years old. Radtec were absolutely fantastic to deal with and Darren was a pleasure to talk to. Duly tested and repaired, they really went above and beyond and will stick in my memory as one of the most helpful companies I've ever had the pleasure of dealing with.

Exactly my experience too.
It makes a refreshing change these days I feel. I seem to have started a debate about antifreeze types by relaying the information I was told.
Just out of curiosity what antifreeze was in your car and what will you put back in it?
Regards Chris.

Mine had red antifreeze in it, as recommended by the company that built my car. Radtec recommended the blue.
But I've since read online that the colour of antifreeze is meaningless. I've read on several websites, most recently Opie Oils: https://www.opieoils.co.uk/pdfs/tech-articles/cool...
It seems there's only really inorganic, and organic. Newer engines need the new organic antifreeze. Older engines and radiators which have copper and brass then it needs inorganic.
I've got an LS3 in mine and from what I've read online, most Corvette owners use Dexcool coolant. Which is a red OAT coolant without silicates. I've put some Comma G30 OAT coolant (red) for now as I had a new 4 litre bottle in the garage anyway. Once I know there are definitely no leaks and it's all working as it should be, then I may well drain it and fill with distilled water and whatever coolant is recommended. Or I may just leave it.

Just to confuse things a little further, local factors here sells pink & blue ethylene glycol - the specs on the labels read identical, so dont judge the fluid just by its colour check what you're getting.
Yes, this is what I understood. Manufacturers can dye it to whatever colour they like. Gassing Station | Chimaera | Top of Page | What's New | My Stuff
