Finaly got a 3sgte engine
Finally got my engine in the garage, took almost a whole day to tidy a space and get it in.
It is for my celica GT4 (ST185), as the last one overheated due to fan switch failure and siezed.
To prevent a repeat i will make an electronic fan controller as a backup. I will add a large oil cooler (with a stat). Is it possible for an oil
cooler if large enough prevent overheating of an engine?
I know my parents astra sri survived with no water in the system (split hose) for some time on the motorway, at lets say and very reasonable speed!!
Lasted for years after said incident fine until some chump wrote it off.
Its a revision 2 engine, so i`m looking to improve the reliability of the engine, first plan is to fit a head gasket from the revision 3 engine, as it
is metal as opposed to paper. Change the bearings (main and rod), and thrust washers. Any other recomendations?
Thanks

LOL you murderer, My coolant never goes hot. Oil gets a bit warm but thats in the back of my rev 3 MR2. How on earth did you overheat it? Even the
fans on mine only really come on when I'm stationary. Oh well. Sure the thermostat and radiator were ok?

I think it had happened before i bought it. As when i bought it the water level was a bit low (0.2- 0.5 l).
As the car ran fine, i decided that the most likely cause was the pressure cap as there was some crud on the seal.
This car has air con so the airflow is limited, as well as the turbo intercooler scoop increasing air pressure in the engine bay.
I was on a track at the time (snetterton) so full power most of the time. When I was recovered the fan did not kick in with the temp scale in the
red.
Thermostat seem to work fine, up to heat quickly, stayed solid as a rock mid scale.

I would tend to agree, pretty unusual for fan failure to cause a seized engine, unless it popped a hose and dumped it's coolant due to the heat?

It is the old fashioned pressure cap type, no expansion bottle.
Might add that to the list.

Even expansion bottles have "old fashioned" pressure caps.
What do you propose expansion bottle does when "expansion space" has gone
I'd have another look iiwy.

Yeah you are right, although, there is a bit more safety margin + air locks are less likely.

Use a cheap gasket set throw away the head gasket but expect to pay about £100 for the steel one also don't forget to have the head checked and
skimmed if neccessary also new cambelt, the son put too much oil in his ST202 Celica and spun a bearing on the crank.
theres a celica engine manual on my webpage in the workshop manuals section if it's any use.

Thanks that is useful. Looking on ebay the st205 gasket set has a multilayer steel, whilst the st185 doesn`t. Un surprisingly st185 is half the cost
as a result.
Thanks
