Been advised to Re-torque head and put Genuine H/Gasket

[Aben Dean]

I recently did a rebuilt on my motor and the its now heating up in long runs and not in short runs. There was no bubbles on radiator before but now when the radiator is topped up it starts throwing bubbles up and puts water into the reserve tank. but when certain amount of water goes off the radiator it stops throwing water into reserve tank and doesnt lose more water from radiator (just about 1L short of making radiator top up). I used a non-genuine head gasket during rebuild which i already had before rebuilt was done. Now my mechanic says to put a genuine head gasket in and will re-torque head. Any idea whats the torque of head bolts on TD42?? Another friend suggests me to use Chemweld to solve my problem...anyone used these before?? The Radiator shop guy told me that it can block my radiator..

Don't use chemiweld. If you plan on keeping the car do it properly. I used an aftermarket gasket first time 40,000 k later started leaking coolant out the side, fitted a genuine one, haven't looked back.

Your mechanic should be able to get head tensions very easily or google it and you will find.

You have sufficient Posts to download the Manuals Mate and the torque's are in them

ok thanks guys... i bought a Genuine H/Gasket today part no: 11044-06J00 and will give it a go and hopefully that will fix my problem of heating in long runs. just hope no issues with head.

Don't use chemiweld unless in the bush in an emergency to get you out.

Is the TD42 got a Turbo on it? Is it just getting hot on a long slog up a long hill? Or on the hwy driving after an hour and it just gets hot?

If its a long hill then maybe you have too much fuel and or not enough boost happening.

Have you got any after market gauges fitted?

when torquing down the head make sure you follow the manuals bolt numbering procedure or you could do damage to the head

its got aftermarket turbo (T3/T4) on a safari kit..... new turbo fuel pump fitted. i have the EGT / Boost gauges. EGT stays ok....boost abt 8psi. goes to 90-100degs when running with A/C and driving for like 20mins with bit of heavy right foot. now recently it has started to push water up the radiator when i try to top up the water.

Get new head bolts as well. Td42 head bolts are a torque turn setting. This is where you torque to a set figure then turn the Bol an extra 90 degrees or whatever the spec says. These types of bolts are a single use item.

The head was opened and tested ok....relief Alhumdulillah!!!!

[93patrol]

That's good so it was just the gasket then


Just tap it in just tappy tappy tappy

Fitted Genuine head gasket.....tested head all ok. drove it....still heats goes past 100deg. fitted new thermostat as well. so tmrw will fit a brandnew radiator and see!

From memory I have seen normal running temp around 104-110 degrees but that was on my motor bike and I could see the actual temp on the dash. Because the cooling is under pressure it can go above normal boiling point. It just when you break that pressure the coolant will instantly boil


Just tap it in just tappy tappy tappy

It might pay to service the radiator too!
Cheers, the ferret.

radiator was serviced but showed no improvement. The Radiator shop here have agreed to give the new radiator for testing, if it solves the problem i will have to buy it! if not then they will return it! not bad i guess....

With above, pretty sure 100'ish is normal..

Patrol thermostats are generally set around the 76 degree mark so 80-90 is normal operating temp.

[Aben Dean]

Ok....new Radiator went in and the heating problem is solved!!!!!!!!! took it for some hard runs (without coolant, just water) and the factory gauge never went above half mark, the aftermarket gauge went max i think about 95degs...... but drops to abt 80-90degs. I have been advised to use water in radiator rather then coolant!

[nissannewby]

Seen your patrol in the latest 4wd action to mate. I must say its a very tidy rig and you have it setup quite well.
