Hi everybody... New Member here...

I bought a TF Magna a few weeks ago, unregistered. it had an Overheating problem, but i still bought it cos it was Cheap.

anyhow, i replaced the stuck/rusted thermostat.. flushed the cooling system. and replaced with nulon coolant.

drove it a bit to test it... but its still over heating... the Fans do kick in. i can hear them from the cabin.
can also hear a gurgling sound sometime.

The temp Gauge in the cluster goes way above the halfway mark.

any Ideas?

the temp drops down after accelerating from a stop/colour light.

had the car running on the drive way yesterday and observed the temp Gauge and its definitely overheating.

any hep is greatly appreciated.

cheers
Kas

Welcome... Maybe you have a faulty thermostat of the shelf... it does happen.As far as the gurgling goes maybe you have some air trapped somewhere in the system..did you have the heater open when you flushed?.

Run it with no thermostat for a test, if that fixes it then replace it again.

wont make a difference, magnas heaters are allways on.
best thing to do is remove the trapped air, park on a uphill slope. and continue to top up coolent.
there was a neat trick to getting the air out, just cant for the life of me remember

If the old thermostat was rusted, it doesn't sound good. Quite likely the radiator could be partially or completely blocked, which is causing the issue.

When was the water pump last replaced?

Squeezing the top and bottom hoses with the radiator cap off always worked on my old camry.

DONT EVER run a Magna with no thermostat and FFS ppl, stop dishing out advice that can destroy engines, if you dont know the consequence in these engines, just STFU and let someone who knows these engines comment. I know you are trying to assist but your advice could cost someone, not just this member but anyone just browsing, an engine

If oyu remove the Thermostat then you will be in a coolant bypass situation. The thermostat has a plate on the bottom which will when the engine is cold have coolant circulate through the motor to allow the motor to warm up sooner, once the motor warms up it will then close off the the bypass hole and pull the coolant from the Radiator.

To start with, you need to do a temp test, see if it is really overheating, then you need to find why. Could be a water pump issue, could still be fans as you need to visually see them running. In short you need to do some proper testing to start this all off and then you will find the issue quick enough

Many thanks to all who replied. :-)

@MadMagna, i have checked visually to see if the Fans do come on and they DO come on. could the water pump be stuck or something? and as for the temp test, how would i go about doing one?

thank you

i would also check the radiator isn't blocked as already stated this can reduce the amount of water in the cooling system and cause problems.

If it's due a cam belt change, replace the water pump at the same time - it's standard practise on these motors & would eliminate one more thing.

I see that you're in Victoria. If in doubt, I'd take it to Madmagna for a checkover - knows pretty much everything there is to know about them & doesn't charge a fortune...

Hey mate i had a very simular problem recently and MADMAGNA helped me sort it .

Mine was that the main fan has a high and low speed on it and the low speed motor had blown! Once i was in traffic the temp guage would go up and then high speed fan with the thermo fan would cool it back to normal. Driving in the hwy, there were no issues.

Quick test is turn on the air con and make sure both fans are spining.

Remember that the main fan has 2 speeds, it may be that only the high speed kicking and cooling it back to normal.

Oh and talking form experience, a siezed water pump makes the car undrivable, you will see smoke coming out of the cam covers because the timing belt will keep wanting to spin and the water pump won't move anymore. Unless it is partly blocked but not sure how this will work.

thanx for the replies and info guys... was very busy past couple of weeks so couldn't get in to this...

as for the seized water pump making the car undriveable and smoke coming out of cam covers, that's not the case here. car drives Great. no smoke from cam covers.

and i also removed the lower hose from the radiator and poured water into the rad. to check if the rad is blocked.. nope its not. seems to flow very well.

i will be fixing the oil leak from the rocker covers tomorrow and change the plugs at the same time since the manifold is off.

then a timing belt and water pump change is in order.

just an update... took the rocker covers to replace the gaskets.... and voila... its all milky inside.. so the head Gaskets are gone....
