Blocked pipes going to the rear heater?
Air-lock still circulating around the cooling system?

Hi Have you had it to a garage and asked them to do head gasket test ?(the thing that tests for gases in the water?) when you say that water is coming out of the exspantion bottle pipe it sounds like there is back pressure there this might be a head gasket problem I had the same problem with mine but the garage that fixed it for me the first time used the wrong gasket depending on which Surf you have there is 3 gaskets for them. I replaced the gasket myself got the right 1 from Roughtrax also new head bolts and she has been ok now for over 2 yrs now (touch wood).

Hope this helps

hi the thing we cant uderstand is had new rad running fine temp normal for 6 weeks then over heat had new pump running fine 2 days now this water dumping out of overflow pipe when running, there's now water in the oil cleane as when it went in,also no oil in the water, before the rad was fitted there would be a lot of smoke , but there is no smoke from back now , starts first time runs good no problems there, if there was a cracked head then surly it would show more signes then just dumping out the water
cheers

sorry ment No water in the oil, when oil cap of still nice black couler no milky stuff

[surfenstein]

do you know how the garage tested the head,did they do a sniffer test.?the thing with a sniffeer test is if you get any of the coolant in the glass pipette when you squeeze the the bulb it renders the test useless.

overheat

did the head and block test with the fluid stayed blue

You wont find this Usually as head cracks near valves

I've had two 2.4s the first one I experienced similar problems to you. I replaced over a period of two years all the things that you have. The condition always improved and the temperature seemed to stabilise but it would often blow water out of the expansion after turning off the ignition. It kept going on regular top ups of water for some time until the other common problem occured i.e. the big end went. When I stripped the engine I discovered that there appeared to be a hair line crack between the valves on no.4.
My second surf I had only had for a month it showed no signs of over heating problems but occasionally blew water from the expansion. Then on a short drive into town then temperature went up and suddenly and turned the truck into a mobile sauna. When I removed this head it had an obvious crack between the vales on no.4 and bad pitting between bores 3 and 4.
Sorry to have been so long winded but I think you'll find that the above experience has been shared by many on and off this site (there are many overheating threads).
By all means check for air locks I hope it is that simple. But I would also get the head test done again and may be a compression check it might show a difference on no. 4.

Rad cap housing? Do you mean thermostat or the actual housing ,what could be wrong with that? I had the same problems as you, changed Tstat and rad cap and all was fine for 1 week and now eratic temp ,cold blowers again.
