Another KZ-TE head

[Hilux01]

Right so again during warm days, when doing a uphill at 110km/h my KZ-TE's heat gauge started rising. No higher than maybe 3/4 of the way.

Nothing serious and only really an issue when loaded + uphills + warm days. Noticed a drop in fuel economy, but no major other issues, went through the cooling system and the radiator cap was "moeg". After replacing the cap the BosMerc started to "hoes en proes" when starting the machine when cold, with a little smoke cloud. Not good

So Silverton radiators did a quick check and tested positive for air, so eighter the gasket or the head has cracked, answer this morning, head has cracked.
Pics below, getting a really good deal from Demo Engineering here in Witbank, replacing the complete head. (also from Italy like Louis')







Complete head goes for R7800 and then obviously gaskets etc and liquids to be added, getting labour for next to nothing, long term friendships pays off

Gonna have the radiator cleaned as well

What else must I remeber while everything is off and taken apart?

Ai Henk, dis nou nie goeie nuus nie.....

Don't forget where you put all the nuts and bolts.....

Thanks Mark

Jip not the best of news, but at least now I know everything will be alright again, rather have it this way than having a blown head somewhere in the bush always something to be greatful for I guess

Hi Henk, can cry with you, just replace my head 3 weeks ago, and had the same problem with heating on uphills. Flushed the radiator and found a lot of lime scale in the bottom part/pipes of the radiator. Seems like everything is fine now. Paid R 8500.00 foet the new head including pressure test and labour. What are the kilo's on your KZ now?

[Hilux01]

Klippies 288 000km approximately

Also having the radiator cleaned, and complete head done, hopefully all will be done by tomorrow afternoon.
Which head did you use?

You still have heat gauge rising on uphills?

Dankie, ek het jou nommer - ek bel jou later. Ek sien jou head het ook na die pre-combustion chamber toe gekraak en tussen die in & outlet valve.
Jy moet maar self besluit, maar ek het die head boute (18X) ook vervang teen R85 'n bout - Toyota het my darem 20% afslag gegee. As jy nog nie jou thermostat vervang het nie, doen dit ook. As jy na my thread kyk sal jy op die onderste foto op bladsy 2 die AMC merk op die head sien. Dit is in gegiet en jy kan dit sien nadat alles aan mekaar gesit is.

Ek het ook R7800 betaal net vir die head. Ek wag nou vir AMC om my te sê wat die maksimum is wat die EGT kan bereik voor ek skade gaan kry. Volgens Head Zone is die 650°C, wat nie 'n probleem is nie, maar as ek sleep is ek seker ek gaan 650 oorskry.

Sterkte

Good luck!

Now I am worried about when mine will go

[Hilux01]

Alles reg,

Gister my bakkie teruggekry, kan nie wag om die verskil te sien nie, behoort brandstof verbruik ens. heel goed te beinvloed.

Henk

Ek is bly. Het jy gekyk of jy 'n AMC head het?

Groete

[Hilux01]

Louis,

Nee was nie AMC head nie een of ander iets ander sal probeer uitvind, my pa werk vir Toyota hier in Witbank en hulle laat doen baie heads by die ou en met dieselfde produk het hulle nog nooit moeilikheid gehad nie. Glo alles sal nou reg wees.

Thanks vir al jou moeite

Henk

Hoe ry jou KZ na die long operasie?

Groete

[Hilux01]

Louis,

Dankie vir die belangstelling, ek nou so amper 700km met hom gery na die operasie en moet se ek kry dat hy beter trek, nou op die eerste tenk om verbruik te bepaal maar nog geen teken gewys van warm loop nie, ek gaan oor 2 naweke langpad vat en redelik gelaai wees ek reken dit sal die toets wees!

It is critical that the engine and radiator is well earthed because the coolant/anti-freeze is getting neutralized and become useless.

Ook belangrike een...ruil op 100 000 die injector tips. As hulle begin over fuel sien mens dit nie want hy rook nie maar die temp syyg en die head kraak. Hier by ons is kz-te wat al 600 000 op het en die engine was nog nie oop nie...tap olie elke 5000 en tips elke 100 000

[Hilux01]

Dankie

Ek gaan dit onthou, ek het die tips gedoen so 40 000km terug.

So hulle is weer due so oor n jaar en n half.
