New Degas Bottle Coolant Cap

My truck had been pushing small amounts of coolant out the degas bottle. I thought it was caused by a bad oil cooler, so next week I am replacing the oil cooler. On a whim yesterday, I went to Bumper to Bumper and bought myself a new Degas Bottle Coolant Cap, it has made a HUGE difference. No more coolant out of the cap, and it seems like my truck has a little bit more pep than it did. For $8.40 I fixed a huge problem....worth it.

Yup. Simple fix for a minor problem. Depending on who you listen to, after some use, 90% of the original caps do not hold past 5 psi. If it still pukes after a new cap, you know you have big problems.

Hehe....i like your optimism, make sure your coolant level is slightly below the min. level. Hope for the best. Btw, if you are not monitoring, you are running a risk of damaging your engine.

Had a similar issue with mine, got a new cap and haven't seen a drop of coolant outside the cap since. Coolant level is holding solid at the new MIN line too. Only negative item I'm having is my deltas are edging towards the high side, did a coolant flush and went from a nice 4-5 degree delta to 8-10. Can't say I didn't know the risk, thanks to this forum, and already gearing up for an oil cooler job.

I'm having the same issue, just did studs one by one, so I oretty much know where this is leading, but ill give the coolant degass cap a shot...perhaps itll solve the problem, could be a weak cap. I only see puking after high speed high boost runs, which in theory shouldn't effect cooling system pressure if head gaskets and all are good.that being said oil temps would get up to 220* and coolant temps right at 210*, just working hard. There is a prayer that perhaps the cap is weak and under higher temps its just not holding pressure. Temps went right back down after i slowed down some. Hard to say, my money would be on head gaskets for mine at this point. I'm gonn Clean everything up and try a cap today, see if it helps.

I'm actually really tempted to hook a pressure gauge up to the cooling system to monitor everything, see I'd I get spikes in pressure at high rpm, high boost. If so it makes diagnosing the head gasket issue much easier.
