I've owned two 2nd gens, a 4 cyl and a V6, and both have cost me more $$$ in cooling system hoses than oil changes. Does anyone have any luck with theirs? I don't know if the last owner put cheap hoses on or what, but I've busted two in the last couple of months and it's lucky I frequently watch the temp gauge, within 30 seconds driving she was up to 3/4

I've never had a hose split on me...That's quite strange. They're the wrong hoses and stretched on or anything like that?

My TR blew radiator hoses all the time.

I think it blew 3-4 in less than 12 months that I owned it, dont have a fix for you but letting you know that youre not the only one with that issue.

Common fault in 2nd gens... I actually spent $100 yesterday and changed every single cooling system hose & replaced all hose clamps too. I've blown 4 hoses in the span of 3 months... *** annoying having to drain & refill the cooling system every fortnight while replacing hoses. :doubt:

I think its mostly to do with people using the wrong coolant types... instead of genuine mitsu coolant. I think galvanic corrosion is also a bit of an issue in these models too.

Genuine cooling system hoses are cheap and apparrently you can get a full hose kit for around $50-60 from mitsu, i didnt however, coz it was saturday and spare parts was closed.

I find the comments on TR hoses being unreliable quite surprising.

MY TR still has the original hoses!!!!!!

I've never used genuine mitsu coolant...never blown a hose..pre and post conversion.

i've blown 2 hoses in my 2nd gen,and needed a new top tank. stupid 2nd gens!!!GRRRR!

I've split a hose or two, the smallest split and the coolant slowly leaked out.


So I replace the two main radiator hoses every so often, I don't use mitsu coolant either - just some slightly more expensive stuff from supercheap...



P.s that was when I first bought the car, havent had a problem for a while

You are all looking at the hoses and not looking at the real problem here.

Screw Genune mits this and that, as they say, russian technology, american technology, all made in china!

The main issue here is, other than old hoses, over pressurisation of your colling system. This can be caused by many things one biggie is wrong coolant/water ratio and after market radiator caps. I use only the ND caps, Toyota sell them cheaper than mits, valvoline or castrol coolant, approx 2.5l in your system rest water.

My verada had all new hoses within a week or purchase and I drove ot for near 5 years with not even so much as a drip except only one time when the fan relay decised to stop.

You forgot German Technology... :P

Thats true to some extent... but over pressurisation doesn't cause pitting, erosion, galvanic corrosion, and a few mitsu's i tested actually had stray current in the cooling system... which has alot to say with the quality of earthing in the 2nd gens. Afaik, the 3L's arent too bad for cooling system problems, but the astrons are another story.. :doubt:

I think you nailed my problem there, I've noticed my hoses get quite tight when they're hot, meaning high pressure, so I took extra measures this round. Altho my budget could only afford Tectaloy 90 plus 33% premix, and I had to add another 1.5 or so Litres of demineralised water, I ran the car for 15-20 mins without the cap on to make sure I didn't overfill it. Have driven it since and checked overflo container, all looks good, and I can actually squeeze the top hose now. Fingers crossed. The car has a 1200km trip to do later this week.

Anybody else who has this problem, I know how ya's feel. lol. It's quite annoying, if my sister was driving, no doubt it would have overheated, she wouldn't have been constantly watching the temp gauge like I do.

Personally I didnt bother with the expensive coolant, I bought a 5L bottle of premix stuff at BigW for like $3.85 or something like that because chances are its gonna end up on the pavement one day anyway. :)

Perhaps thats the reason why lol

Then why not just use tap water...

Generally the cheap stuff is only a type B coolant.. the more expensive ones like the nulon, tectalloy, castrol concentrates are type A, and are what you should be using... unless you drive a falcon.

unless you drive a falcon.

Even they have changed over to ethylene glycol.

Yup..

How dare you use the word Tectalloy on this forum...mods please add this word to the swearfilter immediately lol

Tectalloy has been proven to be the cause of more corrosion than plain good quality water. I was on 60 minutes ages ago a test done with dis similar metals in beakers with various coolants. Tectalloy might as well been acid!

Gashead, you say you use the 3.95 bigw coolant, not flaming you mate but you deserve what you get then

A good quality concentrate diluted at the right amount will do the job nicely, there will be current in a cooling system due to there being different metals. The job of a good coolant is to negate this and stop the corrosion. Coolant has several jobs in a very hostile environment, anti boil, anti freeze, anti corrosion etc etc.

Also watch those crap aftermarket radiator caps, the ND ones are the go and I have solved several members pressurisation problems with this simple thing

Hahaha okies... i'll remember that.
I've never used it so i didn't have a clue exactly what it was like.

Oh wait hang on... i think i'm thinking of the wrong brand possibly :confused: .
Come to think of it, tectalloy is the cheap **** lol.

Whats the stuff that comes in a yellow bottle?

How does that chameleon stuff that starts off red and changes colour perform?
