Hi all i have a 92 celica convertible gt model that i know for a fact has at bare minimum a 3sfe waterpump and thermostat housing. i went to buy a thermostat for it and the 5sfe that i thought was in the car was a 54mm where as the one that is in the car is a 48mm(had them look up an 89 3sfe and low and behold there is my t-stat) so i figure at bare minimum i have a waterpump housing from a 3sfe motor

its possible i have a complete 3sfe motor but the intake says 2200 and valve cover looks different, maybe i have a 3sfe block with a 5sfe head?

any ideas would be greatly appreciated.

Might be interchangeable...

Is it REALLY REALLY slow? A 3sfe in a 5th gen vert would be almost painful to drive...

It's more likely someone put the wrong T-stat in your car, and the larger one is the one that should be there.

save for the fact the larger one will not fit, the t-stat housing is physically smaller than the larger t-stat

the car pulls as well as my 4th gen 3sfe and maybe a little better, i dont know how to tell on the engine size

Check the stamping numbers on the block itself, and go from there.

well looking at the bgb the water pump housing is a seperate part than the water pump so its at least the water pump housing thats the different one, unless maybe its only the t-stat housing that goes to the hose, maybe someone had to get that from the wrecking yard hmm

ok so i found the block id tag on both my 5th gen and 4th gen here goes

5th gen
JT5ST87K7
N0112196


4TH GEN
JT5ST62K6
J7259730

can anyone identify these?

its possible someone slapped the 5s head on a 3s block

ok well i found the block stamp on the side of the engine here it is

5TH GEN
5S--0184775

4TH GEN
3S-0728144

now i know this explains the 3s vs 5s and that it means i have a 5s block but it doesnt explain my t-stat housing because the 3s housing has a sensor in it, the 5s one does not but it does use the smaller t-stat

so i stopped by the toyota dealer and asked them to look up a 5sfe waterpump housing(turns out it comes with the waterpump) however its been supperceeded to the same pump and housing as a 3sfe, ok cool how about a thermostat for the 5sfe they bring me a 48mm thermostat(odd i thought it would be the 54mm tstat) "ok so this is the thermostat for a 5sfe then right?" yes they say well thats odd as that means that napa and autozone are wrong for the tstats for the 5sfe 92

I would say I'm shocked. But I'm not.

when dealing with autozone/napa/discount auto you MUST always bring the old part along with you to make sure the part they give you matches the part you need.

2ksnakeater, i sold autoparts for 4 years and only actually have run accross a few things that were seriously input into the computer wrong such as this, if it was an oddball part to begin with i would bring in a t-stat but ive never sold a t-stat to a customer that was as wrong as this was.
