Here is that chart. It’s always interesting to note that there is a minimum freezing point which is not at 100% glycol, a concept that is often misunderstood.
I stand corrected.
I know it's TBD for now, but I suspect the HG.Truck: Mitsubishi Shogun Sport 2006
Got a problem which started yesterday. Arrived at my farm gate and I could hear a "bubbling" from the engine compartment, so had a look. The overflow from the expansion tank was overflowing and both the tank and radiator were making "bubbling" noises. Dash temp was normal.
Added coolant in the expansion tank this morning and did a test run. Truck was fine for about 35kms until I got to a long hill, started going up and after a few hundred metres, I could hear the "bubbling" noise. Kept going for about 6kms (it's a long slope with steep and nearly flat sections) before stopping.
Been running the engine whilst stationary for a bit now and no "bubbling". Electric fan works, dash temp normal, oil clean. If I squeeze the top rad hose with the rad cap locked, I can push fluid into the expansion tank and with the rad cap unscrewed, no fluid movement, so the rad cap seems ok. Tried with heater blasting or aircon full on, with no problems.
So all I know is everything works fine until the engine is under load to climb a hill. Truck goes fine otherwise (no smoke of any colour), so I'm baffled. Any ideas anyone?
This truck has a hard life as a farm truck and I try to keep a preventative maintenance plan going for it. It passed its annual inspection a few days ago.
TIA
Sorry to hear that; hope the repair costs aren't too high. Or will you do it yourself?Quick catch up....Did a chemical test yesterday and it's the head gasket.
Did you replace the thermostat? They can stick, and / or outright fail. It's easy to replace, (in most cars), and it's a cheap place to start. You can even drop down in temperature a slight bit and see if that helps.little off topic maybe.
I have done timing belt replacement (along with all pulleys, water pump, tensioners) on my forester 2011 with EJ25 DOHC turbo engine at 107k running.
I did accordingly with manual and Utube guys. And assembled back only to find out that it is now overheating when going for like 5km. When idling, it goes back to normal temp.
(Radiator was replaced a month ago.)
What could be the cause guys?
(I reused the coolant cuz its only a month old. But I spilled some and added 0.5L water instead, would concentrate of coolant degrade and cause this mild overheating?)
or any potential cause i can think off maybe overtightening new water pump? (really cant think of any other reason, help me pls)
Thanks for your reply
hi Bill. Yes, it was replaced with radiator. When idling or just turning on heater, temp goes back to normal area.Did you replace the thermostat? They can stick, and / or outright fail.

My older Ford F-150 came with a 195 degree thermostat from the factory. Several years later it started to stick on the initial warmup. So I replaced it with a 180, and never looked back. That was around 1995.
Bleeding never seemed to matter much in most of the older cars. But it can make a big difference in many of the newer models. I know my 5.7 HEMI V-8 has a bleeder valve or screw somewhere. And there is a type of "method" to use it.hi Bill. Yes, it was replaced with radiator. When idling or just turning on heater, temp goes back to normal area.
Does little more water in solution makes it that bad?
or should i try to bleed air for like an hour?
i did bleed the air for like 10minutes cuz it reached normal temp and air bubbles stopped.
