I’m going to be removing my intake manifold to replace 3 knock sensors that have failed . I will actually replace all four of them. The question is should I replace the transmission fluid cooler while I’m there? Its not a problem now but I’d hate to have to do the intake again . Sometimes doing unnecessary maintenance can cause it’s own problems. My risk in the end, but perhaps some of our pros could give some input? Are there other components while I’m in there I should consider as well?
Although much easier with intake off .. not necessary to remove to change exchanger How many years has it been in there - do you know if the coolant was changed at least every 2-3 years since it has been in there ? If maintence is unknown and it has been in there for 17 + years it seems like a good thing to do .. just shop around for a good price
I do my own fluid changes and maintenance so I know all the fluids have been changed within the last two years. I have some prior service history but no mention of a cooler change . I work cheap on my own cars .
You can just inspect it for corrosion on e everything is apart Sent from my moto g power using Tapatalk
I will be taking mine out, inspecting, and cleaning it. I don't know what to expect! My coolant was crystal clear. If it appears to be in good shape I will keep it. They seem to be pretty expensive!
you cannot tell by an external examination if any of the solder joints is bad or if the unit is near disaster! piece of mind is cheaper and better than the cost of dealing with oil in the cooling system and water in the tranny
I meant looking inside .. the little tubes by taking off rubber ends - it should give you directionally how good it looks
That's exactly what I did when replacing my runner gaskets. Since the manifold had to come off anyway, I went ahead and replaced my heat exchanger, coolant gaskets, gave everything a good cleaning. I think I found the exchanger for like $500 so it was a no brainer to do it while I was in there. my silicone boots looked good and I couldn't find an aftermarket replacement in the right size, but definitely inspect them also for leaks. There's no good way to inspect the heat exchanger itself without removing it from the car so might as well play it safe and replace it. I believe there are upgrades out there as well but they run north of a grand.
