Title: Oil cooler
Post by: razzo on 14 January 2016, 20:34:43

Was planning on fitting a new oil cooler over the weekend but wondered if very low outside temps will have a difference on cure time for grey goo needed to seal cooler plate, any advice peeps?

Should be left for 24 hours anyway .

I expect curing time will be effected with low temperatures though like most sealants ,but you may get away with putting a couple of sacks/blankets over topend then closing bonnet.

Best advise would be to wait until above 5c though or indoor job if possible

"amba", so sorry to disagree with you, but the way I understand it, no matter how many blankets you put over the cooler, sooner or later all parts will reach the same low temperature unless there is a source of heat on the cooler and under the blankets. If all parts start off at the low ambient temperature, there won't be any heat to keep in anyway!

My mistake. :( Bigron...natural process of thermal conduction ...its been a long day so brain is working slow. :D

Most sealants dont cure below 5c too well.

Can you warm the block with a fan heater or similar? Should provide enough heat to help curing I would have thought.

Thinking there should be advice on the product  packaging regarding use in cold temps  . . .

or even very hot for that matter   :-\ :-\

The sealant is not a temperature cure product, it cures when oxygen is removed e.g. when it is clamped under a cooler plate.

Not issues with the ambient temperature, 24 hours will still be fine (in fact 3-4 is under normal ambient conditions)

Just wondering,if goo takes 24hrs to "go off" how do garages do the job after all they can't have a "dead" car taking up ramp space for that length of time surely?A mate who works at a Ford garage says the stuff they use goes off in 20 mins.Don't know how pricey their stuff is though.

Here comes another stupid question, Marks DTM: if it cures by oxygen exclusion, why doesn't it go off in the tube?   ???

Because there's oxygen in the tube, (air space) gap.

They do, after a while, once opened.
