Nissan Frontier TD 27 Overheat at 100kph above...help

[frt]

This is my dads ride. It overheats when driven at 100 kph for a long period (about 30 mins). But when slowed down to 80 kph it cools down.

Any suggestions? Any chance this can be the engine thermostat? Is the TD27 sensitive to this?

ohh...have the same problem with my safari.

check your water pump dude.

[frt]

Water pump? Whats the symptom? Did it solve your problem when you changed it?

[boybi]

check first if the radiator have the correct mixture of coolant and water, and not pure water only.

frt...water pump problem nung akin.kasi may tagas na...so pagt humahataw ako...lalong nauubos ang water...so over hat ako nun lagi.

check for leaks...even the radiator cap shoul;d be checked.

hi frt! ito ba yung frontier nakwento ni afrasay sakin? me aftermarket bullbar ba nakakabit? or baka yung temp sensor ang problem...

Check first the Thermostat, it could be stuck already so when the car revs/speed goes up, the coolant flow is inadequate.

It's quite rare for such an engine to overheat. Has the radiator been drained and cleaned already in the past? HOw are the belts?

Check also if theres any water and oil mixing in the cooling system. I'd advise against using the car until the problem can be solved.

yup ito yon. No bullbar. Temp sensor was checked at Rey Electrical ok naman.

Next step would be to check the belts, fans, and radiator then. Try to check also for any signs of oil mixing with the cooling system... That happened sa car ng friend ko and he needed an overhaul (buti nalang di cracked yung block)... he also had the same problems of heating up when the car ran at speed.

Mukhang hindi makahabol ang waterpump mo kasi high speeds lang ang overheat. Ganyan ang W123 ko dati. Pero kahit mag-idle ako maghapon sa traffic hindi nag-ooverheat.
