Hi All,
Apologies if this post is ordinary.
This is Technically my first post since my introduction post a few months ago.
I've tried to read a couple of posts in regards to over heating issues.
However, i feel like i can't relate fully to whats being said.
I've owned my hilux for around about 2 Years now (2007 model)
and its only fairly recently i've been finding that i have over heating issues.
Its not Technically over heating on a day to day basis, However, after reading through a few posts on here i'm abit more concerned then i was before.
I'm finding during normal highway driving ( between 100-110km) my A/C does cut out. And it stays off untill i reduce speed to about 80kms which then it obviously gets the chance to cool down.
Other times I've been travelling up hill without load and I've had to slow right back because my Temp starts to creep up.
I don't go full throttle up hill either before you question that. I'll happily sit on about 60-70kms going up hill in 3rd or 4th gear depending on the incline and whether i can hear the Luxy struggling or not.
This long weekend just gone did it for me and now i'm more concerned then ever.
I've recently bought a new camper trailer and took it out for the long weekend. I headed to a local place in Lithgow for a camping trip. The roads to and from Lithgow aren't considered to bad hill wise, I've done the trip Previously and i thought just in case i'll purchase two 10" Thermo fans and install them on the radiator to help.
The Whole way up to the camp site even the slightest inclines i had to slow back to 40kms and below because the Lux was getting to hot. On the way back there's a Large Incline Sydney siders will know what i'm talking about(Mt Victoria) I chose to stay in 2nd gear and putt along in the slow lane, However this wasn't enough i actually had to stop half way up and wait for the temp to go down before continuing to the top. Once at the top i had to stop again because the temps sky rocketed again. Its almost like the Thermo fans didn't even help the slightest. On the plus side my EXT temps stayed below 400 the whole trip.
I've done basic changes and want a bit more advise before i start spending large amounts of money. I'm hoping that someone else has been in the same situation.
So far i've replaced the Radiator Cap and drained the coolant and ran the cleaner though the cooling system, installed 3 Thermo fans (one on the intercooler and 2 on the radiator)
I'm concerned that i haven't bled the cooling system properly and from what I've read this can cause a large issue.
I drained the coolant from the bottom of the radiator and re-filled the coolant from the bottle on the side of the radiator. i ran the car and when the coolant dropped i'd top up the coolant until it didn't need topping up anymore.
I'm hoping with the information I've provided that this does assist slightly in troubleshooting with me.
I just want some information to work off before i head to the mechanics because i don't want to be taken for a ride once i get there.
My Partner seems to think that my Viscus hub may be faulty and i should replace that or i should organise to get a compression test done. I don't believe the head gasket is gone in the vehicle because the oils not milky, there's no oil in the coolant, i cant see bubbles in the coolant bottle either.
Hopefully someone can give me some insight.
Thank you in advance
