1FZ-FE coolant leak.

[5inchgq]

Righto outers the 100 series has developed a coolant leak which seems to be coming from the head gasket area. Long story short it burst a radiator tank a while ago and the Mrs didn't notice the temp gauge was off the charts , so I replaced the rad, all hoses and the thermostat filled it with coolant and it fired right up, no missing, no strange noises etc. So today I go to check oil and all the usual things and notice what appears to be coolant leaking from under the inlet manifold........

The rad is still full, no air bubbles etc, oils not milky so school me on what it could be.

I can only assume the head warped from the heat it sustained when it was over heated.......


Cheers,

Dan.

there is a hose at the back of the block and i think two small ones that come off the inlet check them out

Thanks mate, it doesn't seem to be a hose, looks like its coming from the area between number one and two cylinders.
Anyone know if there is a welch (sp?) in that area ?

[rickstrap]

yes ithink theres five of them in there very small bout the size of a five cent piece

you have most probably answered your own question?
altho that could have been the cause for the burst hose for a start?
and the answer is its most likely going to be costly!

This is probably the hose 5inchgq is talking about
