HILUX HEAT IS ON

QI

READ with in­ter­est the re­ports of trans­mis­sion over­heat­ing prob­lems in the Toy­ota HiLux be­cause I had the same prob­lem with my 2007 turbo-diesel HiLux SR5 when tow­ing our 1900kg car­a­van. We only got 40km up the high­way on a 40C day when the light came on. I com­plained to Essendon Toy­ota, which checked the car and found noth­ing wrong. Both the dealer and the Toy­ota Cus­tomer Cen­tre in Syd­ney blamed my non-fac­tory bull bar, which I had fit­ted. Af­ter voic­ing my con­cerns about do­ing our planned trip and hav­ing the light com­ing on con­tin­u­ally, Essendon Toy­ota (now Air­port Toy­ota) sent me to an au­to­matic trans­mis­sion work­shop they use for auto prob­lems, and they fit­ted an af­ter-mar­ket oil cooler. I ques­tioned if hav­ing the cooler fit­ted would af­fect my war­ranty and was told there would be no prob­lem, be­cause they had sent me to an au­to­matic trans­mis­sion dealer, and I have a let­ter to this ef­fect. I have since towed the van up hill and down dale at more than 40C and have not had the over­heat light come on again.

Ian John­son, email Well, goes to show what can hap­pen when we in­sist on hav­ing a prob­lem fixed. All of a sud­den there’s a so­lu­tion that works. Any­one else want­ing to tow with a HiLux and, I would also sug­gest, a Prado, should con­sider talk­ing to their dealer about hav­ing a trans­mis­sion oil cooler fit­ted.

EN­GINE BREAK IN

QHOW

long should it take to ‘‘break in’’ the re­con­di­tioned en­gine in my 1984 XE Fal­con, and what is meant by ‘‘break in’’ for an en­gine? When should the 10W-30 oil be changed? Can I then start on the 20W-50, which is what was used be­fore the reco?

Tony Cross­ley, email Break­ing in, some­times also called run­ning in, is the pe­riod when com­po­nents in the en­gine, such as the rings and bear­ings, work in on the sur­faces they are in con­tact with. It’s best in that time that you don’t drive it hard un­der load or at high speed, and it’s a good idea to vary the en­gine speed so you’re not driv­ing it at the same speed all the time. En­gines in to­day’s new cars don’t need much run­ning in at all, ac­cord­ing to the car­mak­ers, but older en­gines do and it’s a good idea to give them 1000-1500km to set­tle in. Swap oils at the end of that pe­riod and you could use a 20W-50 oil at that time.

CLUS­TER FLUS­TER

QTHE

dash­board clus­ter in my 2005 Re­nault Scenic re­cently started re­set­ting it­self. The clock and the odo went back to zero, and within a few days it com­pletely died. I had no speedo, tem­per­a­ture or fuel gauge. My re­search re- vealed that this is a com­mon prob­lem in Europe and the UK, and Re­nault is aware of this man­u­fac­tur­ing fail­ure. Re­nault first handed me a bill of $2000 for the part alone, in a car that is just over four years old and has trav­elled a mere 61,000km. They then came back to me and said my con­tri­bu­tion to a new dash­board clus­ter would be $520. But why should I pay any­thing if it is a man­u­fac­tur­ing fault? Nick­o­las A. Hor­ton, Pas­coe Vale South Re­nault’s of­fer is stan­dard prac­tice within the in­dus­try. The amount they pay is based on the age of the car and the use you have had of the failed part un­til it broke. What they are say­ing is that they can’t fit a part that is four years or so old and done 100,000km or what­ever your car has done, and by fit­ting a brand new part they are re-
