Overheating

[crosswire]

Well the standard toyota temp gauge is bloody useless!
My 80 series got rather damned hot on the weekend and the gauge was sitting at about half way.

When I got out of the truck I heard a strange noise, I investigated further to find the coolant bubbling in the overflow!

I'm pretty sure it's the water pump. There are certainly no signs that its a head gasket, oil doesn't look to bad and no signs of any leaking.

So while I'm at it I plan to;
Flush the radiator good and proper!
Replace water pump, thermostat and all appropriate hoses / radiator cap.

Is there anything else I should do at the same time?
Looks like next weekend (or maybe the one after) will be very busy!
I will be installing an aftermarket temp guage after this little incident. Damn you toyota!

The only thing left to cover is the viscous fluid in the fan clutch. Probably nopt your problem but if you want to cover everything.......

ps: you planning on flushing the rad yourself with a hose or get it done properly at a rad shop (plastic tank off and rod the core)?

Was thinking about doing it myself. But I guess I should rip it all out and give it to someone to do professionally. Better than having to do it all again I guess.
Could it be the head gasket leaking into the exhaust? I don't think it is as there isn't any smoke coming from the exhaust when running, only a small amount when cold.

Ray, Got any recommendations on who to take the raditator to?
I'm in Tingalpa so preferably somewhere around the Bayside.
How much $ will I be looking at to get it done?

Hi Mate
i had mine done in Sydney cost $275 finally fixed it. before i had replaced viscous fan, thermostat and had rad flushed at ultra tune still overheating so the professional flush did the trick
good luck

I would check that you haven't lost any compression in your cylinders to rule out the head gasket completely.

I plan now to get a compression test to make sure it is not the head gasket.
Hopefully that will go well, I think I will try and do the job myself and failing that doing the trick I will just buy a new radiator.
Sounds like it won't be much difference in price between getting one cleaned and having the core rodded and buying a brand new radiator.
