Whats This On My Rad Cap ?

[ktl]

It feels like sand,or mud

I've also get alot of coolant built back up into the expansion tank and sometimes comes out of the overflow pipe after a motorway journey or a good thrashing.

Oil in the coolant?..Need a new Head Gasket?

Could just be a build up of crap from the system aswell..try flushing it all out and adding some new clean coolant in.

could be headgasket or can also happen if you do alot of short journeys.

it's not the oil filler cap it's the rad cap... when was the coolent last checked/changed?

[Russleh]

think he means that if the headgasket was gone then there would be similar at the filler cap.

that looks to me like manky old coolant and nothing more.

give it a flush through and get some new coolant.

Funny how everyone jumps to the headgasket problem, have you checked the state of your oil too? Does it use any oil?

Empty the coolant, flush it through and refill with coolant.

Thanks for all your inputs.

I did a compression test 2 weeks ago and came back around 150 on all 4 cylinders.

I'v just flushed and empited out the radiator and looking down inside the rad, the fins are covered with that gunk. I'v added toyota red mix inside.

Im waiting for a new rad cap to see if it resolves this lift of coolant up the expansion tank, and it dont syphon back into the radiator when cools down ! . (It started overflowing when it was on the rollers)

Thanks dude but i ordered one last wed from tm-developments. Should be with me today or tomorrow!!

i agree with rick might just be a build up of shite in the system

take all pipes off and flush them all out, empty the water bottle and flush all that out, put fresh water in, bleed the system to stop air locks and should be fine
