You need to pop it out to re-seal it.

And they all had stainless coolers from about 95 onwards

But still keep failing

When badly maintained.............

I ad one fail on a Vectra 2.6 with only 38k on the clock and the antifreeze had been replaced.
I asked Vx parts man about it and he said the oil coolers are crap in there construction :-?

Antifreeze changed at the ludicrous 5yr interval no doubt....

Yup must admit Antifreeze changes get neglected but just done mine as owned this car about a year & not sure what prev owner had done, sooo its pretty pink/reddy colour now!!

yeah change my coolant regularly but I need to sort out my coolant leak without the expense of buying a new oil cooler and plate. I'm just wondering if I can reseal the plate without taking the plate off the cooler and draining the oil?

[feeutfo]

Can the oil cooler plate be resealed without removing the oil cooler or pipes?

I have a coolant leak around the edge of my oil cooler, I'm wondering if it can be lifted up enough to reseal it or could I run sealant along the outer edge of the plate to reseal it?

Any insights or knowledge would be appreciated  

leak in oil cooler or oil cooler plate??? i presume from your question that you have not layed eyes on the cooler itself and dont know if cooler itself is ok? although you dont mention oil in the water tank just probs with a leak??
 in wich case ,as myn, just lift clean and reseal. you have to get right out to clean it tho.so no need to buy plate and cooler,not cheep. hope helps

Yeah I don't have oil in the water or any mayo in the oil at all. I seen the oil cooler plate was leaking when I done my thermostat, but I assumed it was just the thermostat housing that was leaking and running down the side of the plate, but when I was underneath the car I seen coolant running over the bell housing and its the only place it could be coming from.

Nope, the plate can not be removed with the cooler still attached if the heads are still fitted.

Thanks Mark, I had a feeling it would have to be taken off, well I better be careful I don't strip any threads and add another couple of hours to the repair time.

Right   after spending the best part of the day trying to unscrew those god dam oil cooler pipes from around the oil filter...... I done a Krakatoa and bent the pipes out of the way when I found out there was not enough clearance to get my crow foot spanner around the oil pipe nuts. I would have to remove the oil filter and filter housing to get the clearance I need. Anyway I want to meet the SOB who thought it was a good idea to put those pipes so f**king close to the oil filter?  

Ok ranting over, my oil cooler looks in good shape not shiny looking all over but I'm sure its not a plain steal one I've got. Question now is how difficult is it to get the oil cooler pipes back into position?

I have pictures of the progress so I will no doubt post them up, taken  before the Krakatoa incident.

Thanks, yip I consulted that before I even started, got the bits I needed minus the oil cooler, plate and bolts. Everything else I got including the gray sealant. Need to put it back together tomorrow.

I know its frowned upon, but ive always bent the cooler pipes instead of undoing them and ive never had any problems. I always fix the rear pipe first as this one is shorter and has less movement, then the front one but I suppose it depends on how much you have bent them.

[Marks DTM Calib]

As I have said before, its easier to remove the pipes and not hard.

Yes, you do have to remove the oil filter and/or housing but, thats dead easy to do.

The trouble I have with bending them is getting them to line up again (the back one is worst) whilst positioning the metal oil seals and inserting the banjo bolt without damaging the oil cooler threads.

I am also concerned about the remaining spring pressure being applied to the joint by the now bent pipes, in theory it should not affect anything but, its another risk.
