Nogsteeds die overheating probleem

[Michael]

Ek dink n bumper speel n baie groot rol as dit kom by die verkoeling. Jou radiator is wat jou engine koel hou en nie die temperatuur onder die bonnet nie.

Ek het na ek my engine rebuild gedoen het al redelik verander aan hoe my bumper voor lyk om meer lug oor die radiator te kry. Ek het n Madman wat my water temp meet soos dit by die engine uit kom en ek het die temperatuur op die highway met omtrent 10 grade afgebring deur net die middelste gedeelte waar die nommerplaat moet sit te verander sodat lug daar kan deur vloei.

Die standaard plastiek air ducts en deflectors wat op die Patrols is speel n groot rol in my opinie en dra by tot baie meer lug or die radiator.
My volgende stap is om soortgelykes weer tussen my bumper en radiator op te sit asook n stuk aan die onderkant tussen die bumper en cradle.

Louis - Please post a photo of your vehicle from the front.

I can not see properly from your profile pic but it looks the same as mine and we did a mod to the number plate position for this exact reason.

Sorry, we seem to have to discussions going on at once here.

I agree that air flow plays a big role.

At sleeds over say 60-80km/h, bumpers, scoops, and ducting can make a huge difference.

But the symptoms Nico described, lugging through thick sand and so forth, i doubt it.
Here you eed a powerful fan and good air flow through the radiator itself and any additional radiators placed directly in front of it, such as A/C condensors and intercoolers.

Having additional electric fans in front can help, but they need to be very powerful and efficient.

We need to bear in mind that, especially on the older cars, the cooling system is pretty marginal at best and the system needs to be in excellent condition to cope with hard work in hot weather.

Here is the Front of my Patrol. I Just set my Timing aswell and i don't hear any ping noises anymore. Got her to 80km in 5th gear up a hill and don't hear anything. Tried to get it to heat up but like i said earlier, it only starts after about 150km or so.
We are coming to Pretoria this weekend so i will see what she does.

Also you will see on the 1st pic that came out sideways, some water under the car, its not my cars water :) Not hating on anyone but there was a Hilux that needed a radiator fix parked in that spot :)

Meer as halfte van jou radiator is toe Louis...

Sal 'n snorkel enigsins help om die temp af te bring?

[Louis Nel]

EK het nie gedink dit kan die bumper ook wees nie, Waar gan ek gaps moet maak om meer lug in te kry? Het iemand die selle TJM as ek wat reg is lat ek kan sien hoe hy lyk?

Louis - I think 1 thing at a time or you will never know what caused it. Timing is done so carry some spanners on your trip. If it continues to heat up then remove those spots and see if that makes a difference.

I like Fanus's idea about doing the same as Michael and then put your number plate on hinges over the fairlead.
