97 Tarago,radiator Problem?

[chainsaw]

Howdy ,

I bought a 97 Tarago.About 2mnths after, had to replace head gasket.

recently it ,(only at intersections)the revs started to drop.Nearly to the point of stalling.

Took it to my mechanic and we took the idler assembly out and cleaned it.Refilled with water but,Now water is spurting from the overflow tank.Water Level drops, We refill it and it does it again.Water temp is perfect,Oil is perfect,It has got me stumped.

Has anybody please got any suggestions.Muchly appreciated

almost sounded like head gasket again. new radiator and thermostat does not explain the missing and revs dropping though? if eventually car wont start and oil level on dip stick rises past full and resiovoir keeps emptying then its Head crack or corrosion on head or badly torqued head at shop 29pound+90 degrees+90 degrees and new head bolts is a must "$50-"..

oh and please tell me it was a wrong wording when you say filled with "water" did you mean Green Coolant?

its very bad for cars to run just water in radiator with modern cars, with time water may corrode the head water ports..With your Thermostat did you match the nob on housing with the little jiggle hole thing on thermostat..

Yeah mate , sorry wrong wording...meant red coolant ,

Sorry about not finishing .

We got rid of the water problem.We only filled up with water for one day to see if it would leak..Never leaked so i bought original Toyota coolant which is actually a red coolant ..Good for 250,000 klm.Haven't had problem yet going well.

Now the missing,.Took to another mechanic .Done a fuel pressure test.bit high.but OK. He thinks it could be Dash pod.Also we have from now on only use premium unleaded (98%)Bit dearer but better for injectors fuel lines etc.and economy..Will keep posted about outcome..

How can I tell if my head gasket has gone on my Tarago?

I thought usually that the oil is cloudy but that is not the case...

The van just overheats all the time and spits out all the coolant!

I had exactly the same problem with my Tarago with the rev's dropping (especially going around round-abouts) the van sometimes stalled.

Under the front passenger seat, there is a thin black rubber hose (has something to do with the air).

In the middle of the hose is a clear/white coloured 1 way valve.

I used to now and then pull the valve out and flush it with CRC/RP7 ensuring I blow out excess CRC.

That went well for a while but last time I took it to the mechanic, he removed the valve completely so the hose goes straight through now...

FIXED IT COMPLETELY...

Also went from getting 450km's to 600km's from each tank of fuel.

Howdy people,

Alls going well with Tarago.Every now and then we just soak the one way valve doo daa.(sorry thats my technical name for it).

blow in it let it dry.all goes well..It gets a build up like clear oily substance..

With our blown head gasket,Tarago just kept spewing out water .The temp showed normal,no milky oil or anything .Mechanic took head to be tested and we found out..

thanking you.chainsaw
