ZD30 Overheating (I think)
Hi Guys,
I just installed a new factory dash temp sender as my old one was jumping all over the shop. took it for a drive this morning and after about 20 mins of driving(mostly downhill) the gauge started warming up. i made it home and let it sit for a few hours, checked levels, plenty of water/coolant in there so took it for another spin to see if it would get hot again. i got less than 2 ks from home and it started getting very hot. took it home, pulled out the radiator, flushed it, reinstalled and put in some brand new coolant. took it for the same drive again and its still getting hot.
just looking for advice on what the next step would be? i checked my invoice from my motor repair in 2015 when it was fully rebuilt, it had a brand new water pump and thermostat installed then? is there any electricals that relate the the motor cooling that i should be checking? or should i be looking to replace the radiator?
any help would be greatly appreciated
cheers
Rusty

I have a radiator pressure test kit if you want to pressure test the system - is it actually leaking or consuming water? Could be the thermostat - thats another starting point.

G’day Nicko mate, check the engine fan is fully or near locked up when it’s hot and turned off. Viscous coupling could be failing possibly?

Too many Wheat beers for YOU possibly, all the above may or may not be his answer needed? Worth a quick check though, hopefully a simple fix, Happy Days ;-)

not consuming water, and no bubbles coming outta the radiator, i dont think its motor related, the motor is only 3 years old and has done less than 20 thou. i hope its not thermostat thats only 3 years old and its in a prick of a spot to get to lol

Hey Nic. Since you installed a " new" temp sender, could that actually be faulty or not wired right maybe ???
Just brainstorming.

Do you mean it’s turning when car is hot and turned off and or turning when running mate?
Only reason I genuinely ask is that Growler & Rainsey here & many others all experienced not fully locking up when hot needed they found.

could be a possibility, i bought it from atoc(on here) its a genuine temp sender, and all i did was unbolt the old one and plug in the new one.
