Evans coolant

[Stuartieboy]

Hi all,

I have posted in 'introduce yourself' just now looking for tips, I'm going to look at a '93 LJ78 2.4 diesel next week.
Reading about the head and overheating issues, I was wondering if anyone has used Evans coolant before? It's waterless, so less presure on the system, but it's expensive.


Any thoughts?

Hi

I think the best thing you can do for the cooling system is:
- to make sure the viscous fan/clutch is working correctly
- the cooling system is flushed
- and that the radiator is in good condition (and of good quality)
- get a decent after market temp gauge fitted. Toyota ones are hopeless.

Low pressure coolant isn't likely to help you at all on this one.

Good luck with the purchase.

Cool, thanks for that (no pun intended)

There is a theory that the head cracking is caused by a poorly designed head that allows a heat build up between cylinders 3 & 4.

Replacement heads tend to be pattern ie a direct copy, so inherently the same. AMC heads get a good report for resistance but are mucho ££££.

Thing is that it doesnt happen on every engine, I know Jimbo's was ultra reliable and capable of a good turn of speed, certainly I never had an issue with overheating, albeit 60mph was a good cruising speed.

Its a 20 year old truck, with an engine with issues, but as a result prices are relatively low for a LC.

That's why I thought the Evans stuff might be a good idea, people are recommending Water Wetter, so the Evans stuff does the same at that, but more so and doesn't have the corrosive effects of water.

As I said however, it ain't cheap, so if others have found other / better methods, I'll happily use them!

As I said before ... your much better spending the £200 odd pounds on the above remedies
