Strange overheating problem, HELP!
 

I really need some help of you guys. I got a 13B-RE(cosmo engine) that acts very strange. When I start the engine and the temp is rising the waterhoses starts to expand, they almost look like balloons. It does not overheat at idle but as soon as I start driving the temp rises too high.

I have changed the thermostat, both caps, waterhoses and I have checked the waterpump and its looks OK.
The car starts easily and it doesnt missfire. Have checked the plugs and there is no sign of coolant on them neither in the rotor housing.

I know that it can be a bad water seals but I would like to exlude everything else first.

HELP!

What happend, I wrote the thread but it says that "[SLO NIZ]" dit it?

Anyway Im the one that have the problem! :)

Does the coolant circulate at all?

you might want to check the radiator passages for blockage. Sounds like half the rad is clogged up.

I have a brand new Koyo, so it should be ok. Maybe the block is clogged!?

Just in case...make sure that you installed the thermostat in the correct side up....good luck Wankelman...
